Impact of oral intervention on the oral and overall health of children living with HIV in Cambodia: a randomized controlled trial.

BACKGROUND: Maintaining oral health is essential for improving overall health of children living with HIV. Therefore, we evaluated the effectiveness of an oral health intervention for improving their oral and overall health. In addition, we examined their longitudinal association between changes in oral and overall health. METHODS: We conducted a 2-year randomized controlled trial involving children living with HIV in Cambodia. Children aged 3-15 years and their caregivers were randomly allocated either to the intervention (group A) or control (group B) arm. A second control arm (group C) included children without HIV. The group A children received oral health education sessions and practiced home-based daily care. RESULTS: In the baseline survey, 482 children participated (group A: n = 160, group B: n = 168, group C: n = 154), and 350 completed the endline survey. An interaction effect in teeth brushing duration was observed in children in group A relative to group B (AOR = 2.69, 95% CI: 1.37-5.31) and group C (AOR = 3.78, 95% CI: 1.70-8.40). Longitudinal associations were observed between changes in oral hygiene and overall health, as presented by alterations in dental caries in permanent teeth with viral load detection (adjusted odds ratio = 3.58, 95% CI: 1.10 - 11.73), in salivary flow quantity with the overall quality of life (ß = 0.07, 95% CI: < 0.01 - 0.13), as well as in dental caries, salivary pH, debris index with body mass index for age among group A children. CONCLUSIONS: Oral health intervention may improve oral care behaviors and potentially enhance overall health among children living with HIV in antiretroviral therapy in a resource-constrained setting. TRIAL REGISTRATION: ISRCTN 15177479.

Evaluation of a package of continuum of care interventions for improved maternal, newborn, and child health outcomes and service coverage in Ghana: A cluster-randomized trial.

BACKGROUND: In low- and middle-income countries (LMICs), the continuum of care (CoC) for maternal, newborn, and child health (MNCH) is not always complete. This study aimed to evaluate the effectiveness of an integrated package of CoC interventions on the CoC completion, morbidity, and mortality outcomes of woman-child pairs in Ghana. METHODS AND FINDINGS: This cluster-randomized controlled trial (ISRCTN: 90618993) was conducted at 3 Health and Demographic Surveillance System (HDSS) sites in Ghana. The primary outcome was CoC completion by a woman-child pair, defined as receiving antenatal care (ANC) 4 times or more, delivery assistance from a skilled birth attendant (SBA), and postnatal care (PNC) 3 times or more. Other outcomes were the morbidity and mortality of women and children. Women received a package of interventions and routine services at health facilities (October 2014 to December 2015). The package comprised providing a CoC card for women, CoC orientation for health workers, and offering women with 24-hour stay at a health facility or a home visit within 48 hours after delivery. In the control arm, women received routine services only. Eligibility criteria were as follows: women who gave birth or had a stillbirth from September 1, 2012 to September 30, 2014 (before the trial period), from October 1, 2014 to December 31, 2015 (during the trial period), or from January 1, 2016 to December 31, 2016 (after the trial period). Health service and morbidity outcomes were assessed before and during the trial periods through face-to-face interviews. Mortality was assessed using demographic surveillance data for the 3 periods above. Mixed-effects logistic regression models were used to evaluate the effectiveness as difference in differences (DiD). For health service and morbidity outcomes, 2,970 woman-child pairs were assessed: 1,480 from the baseline survey and 1,490 from the follow-up survey. Additionally, 33,819 cases were assessed for perinatal mortality, 33,322 for neonatal mortality, and 39,205 for maternal mortality. The intervention arm had higher proportions of completed CoC (410/870 [47.1%]) than the control arm (246/620 [39.7%]; adjusted odds ratio [AOR] for DiD = 1.77; 95% confidence interval [CI]: 1.08 to 2.92; p = 0.024). Maternal complications that required hospitalization during pregnancy were lower in the intervention (95/870 [10.9%]) than in the control arm (83/620 [13.4%]) (AOR for DiD = 0.49; 95% CI: 0.29 to 0.83; p = 0.008). Maternal mortality was 8/6,163 live births (intervention arm) and 4/4,068 live births during the trial period (AOR for DiD = 1.60; 95% CI: 0.40 to 6.34; p = 0.507) and 1/4,626 (intervention arm) and 9/3,937 (control arm) after the trial period (AOR for DiD = 0.11; 95% CI: 0.11 to 1.00; p = 0.050). Perinatal and neonatal mortality was not significantly reduced. As this study was conducted in a real-world setting, possible limitations included differences in the type and scale of health facilities and the size of subdistricts, contamination for intervention effectiveness due to the geographic proximity of the arms, and insufficient number of cases for the mortality assessment. CONCLUSIONS: This study found that an integrated package of CoC interventions increased CoC completion and decreased maternal complications requiring hospitalization during pregnancy and maternal mortality after the trial period. It did not find evidence of reduced perinatal and neonatal mortality. TRIAL REGISTRATION: The study protocol was registered in the International Standard Randomised Controlled Trial Number Registry (90618993).

Natto extract, a Japanese fermented soybean food, directly inhibits viral infections including SARS-CoV-2 in vitro.

Natto, a traditional Japanese fermented soybean food, is well known to be nutritious and beneficial for health. In this study, we examined whether natto impairs infection by viruses, such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as well as bovine herpesvirus 1 (BHV-1). Interestingly, our results show that both SARS-CoV-2 and BHV-1 treated with a natto extract were fully inhibited infection to the cells. We also found that the glycoprotein D of BHV-1 was shown to be degraded by Western blot analysis and that a recombinant SARS-CoV-2 receptor-binding domain (RBD) was proteolytically degraded when incubated with the natto extract. In addition, RBD protein carrying a point mutation (UK variant N501Y) was also degraded by the natto extract. When the natto extract was heated at 100 °C for 10 min, the ability of both SARS-CoV-2 and BHV-1 to infect to the cells was restored. Consistent with the results of the heat inactivation, a serine protease inhibitor inhibited anti-BHV-1 activity caused by the natto extract. Thus, our findings provide the first evidence that the natto extract contains a protease(s) that inhibits viral infection through the proteolysis of the viral proteins.

Dental caries in association with viral load in children living with HIV in Phnom Penh, Cambodia: a cross-sectional study.

BACKGROUND: Oral health status is associated with the overall health among people living with human immunodeficiency virus (HIV) infection. However, it is unclear whether dental caries is associated with the viral load in this population. Particularly, dental caries among children living with HIV needs better understanding as this can affect their overall health and future well-being. This study assessed the association between dental caries and viral load among children living with HIV in Phnom Penh, Cambodia. METHODS: This cross-sectional study, conducted at the National Pediatric Hospital as a baseline survey of a randomized controlled trial, included 328, 3-15-year-old children living with HIV and their primary caregivers. Calibrated and trained examiners conducted oral examinations for dental caries (DMFT/dmft index) in the children and retrieved the latest HIV viral load data from the hospital's patient information system. On the dental examination day, the children and their caregivers were invited to answer a questionnaire-based interview. Multiple logistic regression analysis was conducted to assess the association between dental caries and viral load. The cut-off point for undetectable viral load was set at < 40 copies/mL. RESULTS: Data from 328 children were included in the analysis; 68.3% had an undetectable viral load. The mean DMFT/dmft was 7.7 (standard deviation = 5.0). Adjusted regression analysis showed that dental caries in permanent or deciduous teeth was positively associated with detectable viral load (adjusted odds ratio [AOR]: 1.07, 95% confidence interval [CI]: 1.01-1.14). Conversely, antiretroviral therapy of ≥ 1 year and self-reported better adherence to antiretroviral drugs were negatively associated with detectable viral load. Among children with detectable viral load, dental caries in permanent or deciduous teeth was positively associated with non-suppression of viral load (> 1000 copies/mL) (AOR: 1.12, CI: 1.03-1.23). CONCLUSIONS: Dental caries was associated with viral load status detection among children living with HIV. This finding suggests that dental caries may affect their immune status. The oral health of children living with HIV should be strengthened, and further research is needed to clarify the causal relationship between viral load and oral health status.

Nutritional status and dietary diversity of school-age children living with HIV: a cross-sectional study in Phnom Penh, Cambodia.

BACKGROUND: HIV/AIDS continues to be a major public health concern for children. Each day, worldwide, approximately 440 children became newly infected with HIV, and 270 children died from AIDS-related causes in 2018. Poor nutrition has been associated with accelerated disease progression, and sufficient dietary diversity is considered a key to improve children's nutritional status. Therefore, this study aims to 1) examine nutritional status of school-age children living with HIV in Phnom Penh, Cambodia, and 2) identify factors associated with their nutritional status, especially taking their dietary diversity into consideration. METHODS: This cross-sectional study was conducted in May 2018 within the catchment area of the National Pediatric Hospital, Cambodia. Data from 298 children and their caregivers were included in the analyses. Using semi-structured questionnaires, face-to-face interviews were conducted to collect data regarding sociodemographic characteristics, quality of life, and dietary diversity. To assess children's nutritional status, body weight and height were measured. Viral load and duration of antiretroviral therapy (ART) were collected from clinical records. Multiple logistic regression analyses were performed to identify factors associated with stunting and wasting. RESULTS: Of 298 children, nearly half (46.6%) were stunted, and 13.1% were wasted. The mean number of food groups consumed by the children in the past 24 h was 4.6 out of 7 groups. Factors associated with children's stunting were age (adjusted odds ratio [AOR] 2.166, 95% confidence interval [CI]: 1.151, 4.077), household wealth (AOR 0.543, 95%CI: 0.299, 0.986), duration of receiving ART (AOR 0.510, 95%CI: 0.267, 0.974), and having disease symptoms during the past 1 year (AOR 1.871, 95%CI: 1.005, 3.480). The only factor associated with wasting was being male (AOR 5.304, 95%CI: 2.210, 12.728). CONCLUSIONS: Prevalence of stunting was more than double that of non-infected school-age children living in urban areas in Cambodia. This highlights the importance of conducting nutritional intervention programs, especially tailored for children living with HIV in the country. Although dietary diversity was not significantly associated with children's nutritional status in this study, the findings will contribute to implementing future nutritional interventions more efficiently by indicating children who are most in need of such interventions in Cambodia.

Malaria knowledge, preventive actions, and treatment-seeking behavior among ethnic minorities in Ratanakiri Province, Cambodia: a community-based cross-sectional survey.

BACKGROUND: Malaria incidence has been steadily declining in Cambodia, where the government is aiming to eliminate malaria by 2025. Successful malaria elimination requires active engagement and participation of communities to recognize malaria symptoms and the development of prompt treatment-seeking behavior for early diagnosis and appropriate treatment. This study examined malaria knowledge, preventive actions, and treatment-seeking behavior among different groups of ethnic minorities and Khmer in Ratanakiri Province, Cambodia. METHODS: Face-to-face interviews were conducted in December 2015, targeting 388 mothers with children under 2 years old, who belonged to ten ethnic minority groups or the Khmer group living in 62 rural villages in Ratanakiri. In addition to describing mothers' knowledge and actions for malaria prevention, logistic regression analysis was performed to identify determinants of fever during the most recent pregnancy and among children under two. RESULTS: Overall 388 mothers were identified for enrollment into the study of which 377 (97.2%) were included in analyses. The majority of mothers slept under bed nets at home (95.8%) and wore long-sleeved clothes (83.8%) for malaria prevention. However, knowledge of malaria was limited: 44.6% were aware of malaria symptoms, 40.6% knew the malaria transmission route precisely, and 29.2% knew of mosquito breeding places. Staying overnight at a farm hut was significantly associated with having fever during the most recent pregnancy (adjusted odds ratio [AOR] 2.008, 95% confidence interval [CI]: 1.215-3.321) and a child having fever (AOR 3.681, 95% CI 1.943-6.972). Mothers' partaking in a variety of malaria preventive actions was protective against fever in children (AOR 0.292, 95% CI: 0.136-0.650). Among those who had fever during pregnancy, 39.4% did not seek treatment. CONCLUSION: Although the majority of mothers took malaria preventive actions, knowledge of malaria epidemiology and vector ecology and treatment-seeking behavior for fever were limited. Staying overnight at farm huts, regardless of the differences in socio-demographic and socio-cultural characteristics, was strongly associated with fever episodes during pregnancy and childhood. This study indicates the necessity of spreading accurate malaria knowledge, raising awareness of health risks related to agricultural practices, and promoting treatment-seeking behavior among ethnic minorities to strengthen their engagement in malaria elimination.

Education and indoor smoking among parents who smoke: the mediating role of perceived social norms of smoking.

BACKGROUND: Parents with less formal education are more likely to smoke indoors, causing socioeconomic disparity in children's exposure to second-hand smoke. However, little is known about the roles of social factors in the socioeconomic gradients of indoor smoking. We tested the potential mediating role of perceived smoking norms on the associations between education and indoor smoking among parents who smoke. METHODS: In this cross-sectional study, 822 smoking fathers and 823 smoking mothers, who lived with young children and were members of a Japanese online survey panel, participated. Structural equation modelling tested the mediating effects of perceived descriptive and subjective norms on the association between education and indoor smoking. RESULTS: Perceived pro-smoking norms, which were more prevalent among less-educated parents, mediated the association between education and indoor smoking. Household smoking status and worksite smoking ban also mediated this association via perceived norms, but only for fathers. Perceived descriptive norms explained 28.5% of the association for fathers and 37.6% for mothers; the corresponding percentages for perceived subjective norms were 9.8% and 26.6%, respectively. CONCLUSIONS: Perceived smoking norms, household smoking status, and a worksite smoking ban could be vital targets of a strategy aimed at reducing the socioeconomic disparity in parental home smoking behaviours.

Improving feeding and growth of HIV-positive children through nutrition training of frontline health workers in Tanga, Tanzania.

BACKGROUND: Nutrition training can boost competence of health workers to improve children's feeding practices. In this way, child undernutrition can be ameliorated in general populations. However, evidence is lacking on efficacy of such interventions among Human Immunodeficiency Virus (HIV)-positive children. We aimed to examine the efficacy of a nutrition training intervention to improve midlevel providers' (MLPs) nutrition knowledge and feeding practices and the nutrition statuses of HIV-positive children in Tanga, Tanzania. METHODS: This cluster-randomized controlled trial was conducted in 16 out of 32 care and treatment centers (CTCs) in Tanga. Eight CTCs were assigned to the intervention arm and a total of 16 MLPs received nutrition training and provided nutrition counseling and care to caregivers of HIV-positive children. A total of 776 pairs of HIV-positive children and their caregivers were recruited, of whom 397 were in the intervention arm. Data were analyzed using instrumental variable random effects regression with panel data to examine the efficacy of the intervention on nutrition status through feeding practices. RESULTS: Mean nutrition knowledge scores were higher post-training compared to pre-training among MLPs (37.1 vs. 23.5, p < 0.001). A mean increment weight gain of 300 g was also observed at follow-up compared to baseline among children of the intervention arm. Feeding frequency and dietary diversity improved following the intervention and a 6 months follow-up (p < 0.001). An increase in each unit of feeding frequency and dietary diversity were associated with a 0.15-unit and a 0.16-unit respectively decrease in the child underweight (p < 0.001). CONCLUSIONS: Nutrition training improved nutrition knowledge among MLPs caring for HIV-positive children attending CTCs in Tanga, Tanzania. Caregivers' feeding practices also improved, which in turn led to a modest weight gain among HIV-positive children. To sustain weight gain, efforts should be made to also improve households' food security and caregivers' education in addition to inservice nutrition trainings. The protocol was registered on 15/02/2013, before the recruitment at ISRCTN trial registry with the trial registration number: ISRCTN65346364.

An investigation of stigmatizing attitudes towards people living with HIV/AIDS by doctors and nurses in Vientiane, Lao PDR.

BACKGROUND: Despite global efforts, HIV-related stigma continues to negatively impact the health and well-being of people living with HIV/AIDS. Even in healthcare settings, people with HIV/AIDS experience discrimination. Anecdotal evidence suggests that healthcare professionals in the Lao People's Democratic Republic, a lower-middle income country situated in Southeast Asia, stigmatize HIV/AID patients. The purpose of this study was to assess HIV stigmatizing attitudes within Laotian healthcare service providers and examine some of the factors associated with HIV/AIDS-related stigma among doctors and nurses. METHODS: A structured questionnaire, which included a HIV-related stigma scale consisting of 17 items, was self-completed by 558 healthcare workers from 12 of the 17 hospitals in Vientiane. Five hospitals were excluded because they had less than 10 staff and these staff were not always present. The questionnaire was pre-tested with 40 healthcare workers. Descriptive statistical analysis was performed and comparisons between groups undertaken using chi-square test and t-test. Bivariate and multiple linear regression analyses were carried out to examine the associations between stigmatizing attitudes and independent variables. RESULTS: Out of the 558 participating healthcare workers, 277 (49.7%) were doctors and 281 (50.3%) were nurses. Nearly 50% of doctors and nurses included in the study had high levels of stigmatizing attitudes towards people living with HIV/AIDS. Across the different health professionals included in this study, lower levels of HIV/AIDS knowledge were associated with higher levels of stigmatizing attitudes towards people living with HIV/AIDS. Stigmatizing attitudes, including discrimination at work, fear of AIDS, and prejudice, were lower in healthcare workers with more experience in treating HIV/AIDS patients. CONCLUSIONS: This study is the first to report on HIV/AIDS-related stigmatization among healthcare workers in Lao PDR. Stigmatizing attitudes contribute to missed opportunities for prevention, education and treatment, undermining efforts to manage and prevent HIV. Reversing stigmatizing attitudes and practices requires interventions that address affective, cognitive and behavioral aspects of stigma. Alongside this, health professionals need to be enabled to enact universal precautions and prevent occupational transmission of HIV.

Gender difference in early initiation of methamphetamine use among current methamphetamine users in Muse, Northern Shan State, Myanmar.

BACKGROUND: Globally, methamphetamine (MA) use is a significant public health concern due to unprecedented health effects of its use. However, gender similarities and differences in early age of MA initiation and its risk factors among current MA users have been understudied in a developing country setting. METHODS: A community-based, cross-sectional study was conducted using a computer assisted self-interviewing program from January to March 2013 in Muse, Northern Shan State, Myanmar. A total of 1362 (775 male and 587 female) self-reported current MA users aged between 18 and 35 years were recruited using respondent-driven sampling. Two gender-stratified multiple logistic regression models (models I and II) were done for analysis. RESULTS: For similarities, 73.0% of males and 60.5% of females initiated MA before their 18th birthday. The early age of MA initiation was positively associated with the reasons and places of the first time MA use among both genders. For differences, males [hazard ratio 1.35; 95% confidence interval, 1.18-1.54] had a significantly higher risk than females to initiate MA at earlier age. Among male users, participants who had bisexual/homosexual preferences were more likely to initiate MA use earlier. In contrast, female users who exchanged sex for money and/or drugs were more likely to initiate MA in earlier age. CONCLUSIONS: More than 60.0% of male and female participants initiated MA use early; however, males initiated use earlier than females. Although similarities were found among both genders, differences found in key risk factors for early age MA initiation suggest that gender-specific, MA prevention programs are urgently needed in Myanmar.

Ability of HIV Advocacy to Modify Behavioral Norms and Treatment Impact: A Systematic Review.

BACKGROUND: HIV advocacy programs are partly responsible for the global community's success in reducing the burden of HIV. The rising wave of the global burden of noncommunicable diseases (NCDs) has prompted the World Health Organization to espouse NCD advocacy efforts as a possible preventive strategy. HIV and NCDs share some similarities in their chronicity and risky behaviors, which are their associated etiology. Therefore, pooled evidence on the effectiveness of HIV advocacy programs and ideas shared could be replicated and applied during the conceptualization of NCD advocacy programs. Such evidence, however, has not been systematically reviewed to address the effectiveness of HIV advocacy programs, particularly programs that aimed at changing public behaviors deemed as risk factors. OBJECTIVES: To determine the effectiveness of HIV advocacy programs and draw lessons from those that are effective to strengthen future noncommunicable disease advocacy programs. SEARCH METHODS: We searched for evidence regarding the effectiveness of HIV advocacy programs in medical databases: PubMed, The Cumulative Index to Nursing and Allied Health Literature Plus, Educational Resources and Information Center, and Web of Science, with articles dated from 1994 to 2014. Search criteria. The review protocol was registered before this review. The inclusion criteria were studies on advocacy programs or interventions. We selected studies with the following designs: randomized controlled design studies, pre-post intervention studies, cohorts and other longitudinal studies, quasi-experimental design studies, and cross-sectional studies that reported changes in outcome variables of interest following advocacy programs. We constructed Boolean search terms and used them in PubMed as well as other databases, in line with a population, intervention, comparator, and outcome question. The flow of evidence search and reporting followed the standard Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. DATA COLLECTION AND ANALYSIS: We selected 2 outcome variables (i.e., changing social norms and a change in impact) out of 6 key outcomes of advocacy interventions. We assessed the risk of bias for all selected studies by using the Cochrane risk-of-bias tool for randomized studies and using the Risk of Bias for Nonrandomized Observational Studies for observational studies. We did not grade the collective quality of evidence because of differences between the studies, with regard to methods, study designs, and context. Moreover, we could not carry out meta-analyses because of heterogeneity and the diverse study designs; thus, we used a narrative synthesis to report the findings. MAIN RESULTS: A total of 25 studies were eligible, of the 1463 studies retrieved from selected databases. Twenty-two of the studies indicated a shift in social norms as a result of HIV advocacy programs, and 3 indicated a change in impact. We drew 6 lessons from these programs that may be useful for noncommunicable disease advocacy: (1) involving at-risk populations in advocacy programs, (2) working with laypersons and community members, (3) working with peer advocates and activists, (4) targeting specific age groups and asking support from celebrities, (5) targeting several, but specific, risk factors, and (6) using an evidence-based approach through formative research. Author conclusions. HIV advocacy programs have been effective in shifting social norms and facilitating a change in impact. PUBLIC HEALTH IMPLICATIONS: The lessons learned from these effective programs could be used to improve the design and implementation of future noncommunicable disease advocacy programs.

Motivation and incentive preferences of community health officers in Ghana: an economic behavioral experiment approach.

BACKGROUND: Health worker shortage in rural areas is one of the biggest problems of the health sector in Ghana and many developing countries. This may be due to fewer incentives and support systems available to attract and retain health workers at the rural level. This study explored the willingness of community health officers (CHOs) to accept and hold rural and community job postings in Ghana. METHODS: A discrete choice experiment was used to estimate the motivation and incentive preferences of CHOs in Ghana. All CHOs working in three Health and Demographic Surveillance System sites in Ghana, 200 in total, were interviewed between December 2012 and January 2013. Respondents were asked to choose from choice sets of job preferences. Four mixed logit models were used for the estimation. The first model considered (a) only the main effect. The other models included interaction terms for (b) gender, (c) number of children under 5 in the household, and (d) years worked at the same community. Moreover, a choice probability simulation was performed. RESULTS: Mixed logit analyses of the data project a shorter time frame before study leave as the most important motivation for most CHOs (ß 2.03; 95 % CI 1.69 to 2.36). This is also confirmed by the largest simulated choice probability (29.1 %). The interaction effect of the number of children was significant for education allowance for children (ß 0.58; 95 % CI 0.24 to 0.93), salary increase (ß 0.35; 95 % CI 0.03 to 0.67), and housing provision (ß 0.16; 95 % CI -0.02 to 0.60). Male CHOs had a high affinity for early opportunity to go on study leave (ß 0.78; 95 % CI -0.06 to 1.62). CHOs who had worked at the same place for a long time greatly valued salary increase (ß 0.28; 95 % CI 0.09 to 0.47). CONCLUSIONS: To reduce health worker shortage in rural settings, policymakers could provide "needs-specific" motivational packages. They should include career development opportunities such as shorter period of work before study leave and financial policy in the form of salary increase to recruit and retain them.

Caregivers' treatment-seeking behaviour for children under age five in malaria-endemic areas of rural Myanmar: a cross-sectional study.

BACKGROUND: A community-based malaria intervention was introduced through fixed and mobile clinics in rural Myanmar. This study attempted to identify treatment-seeking behaviour of caregivers for children under five and the determinants of appropriate treatment-seeking behaviour in mobile clinic villages (MV) and non-mobile clinic villages (NMV) in malaria-endemic rural areas in Myanmar. METHODS: A cross-sectional study was conducted in 23 MV and 25 NMV in Ingapu Township, Myanmar. Appropriate treatment-seeking behaviour was operationally defined as seeking treatment from trained personnel or at a health facility within 24 hours after the onset of fever. Multiple logistic regression analyses were conducted to identify the determinants of appropriate treatment-seeking behaviour. RESULTS: Among the 597 participants in both types of villages, 166 (35.3%) caregivers sought appropriate treatment. No significant difference in appropriate treatment-seeking behaviour was found between the two types of villages (adjusted odds ratio (AOR), 0.80; 95% confidence interval (CI), 0.51-1.24). Determinants of behaviour include proximity to public health facilities (AOR, 5.86; 95% CI, 3.43-10.02), knowledge of malaria (AOR, 1.90; 95% CI, 1.14-3.17), malaria prevention behaviour (AOR, 1.76; 95% CI, 1.13-2.76), treatment at home (AOR, 0.26; 95% CI, 0.15-0.45), and treatment and transportation costs (AOR, 0.52; 95% CI, 0.33-0.83). CONCLUSIONS: Caregivers' treatment-seeking behaviour was poor for fever cases among children under age five, and did not differ significantly between MV and NMV. It is necessary to educate caregivers, particularly for early treatment seeking and appropriate use of health care options for fever, and catering to their medical needs. These findings can help promote awareness and prevention, and improve the quality of interventions at the community level.

What are the factors associated with depressive symptoms among orphans and vulnerable children in Cambodia?

BACKGROUND: Compared to general children, orphans and vulnerable children (OVC) are more exposed to negative outcomes in life such as abuse and neglect. Consequently, OVC are more susceptible to depression. This paper investigated factors associated with depressive symptoms among OVC in Cambodia. METHODS: In this cross-sectional study, data of 606 OVC from the Sustainable Action against HIV and AIDS in Communities (SAHACOM) project were analyzed. The data were collected from five provinces and analyzed separately for boys and girls. Multiple linear regression analysis was used to identify factors independently associated with levels of depressive symptoms. RESULTS: Both boys and girls who reported having been too sick making them unable to attend school or go to work in the past six months (boys: B = 3.5; 95 % CI = 0.7, 6.2; girls: B = 5.7; 95 % CI = 2.9, 8.5) and who had witnessed violence in the family (boys: B = 5.6; 95 % CI = 1.6, 9.6; girls: B = 5.8; 95 % CI = 1.7, 9.9) had a higher level of depressive symptoms. Girls who were older (B = 8.5; 95 % CI = 3.0, 14.0), who did not have enough food in the past six months (B = -8.7; 95 % CI = -13.7, -3.7) and whose parents were separated, divorced or dead (B = 3.9; 95 % CI = 0.5, 7.2) had a higher level of depressive symptoms. Higher level of school attachment was negatively associated with depressive symptoms in both genders (boys: B = -1.4; 95 % CI = -2.0, -0.9; girls: B = -1.4; 95 % CI = -2.0,-0.9). CONCLUSIONS: Factors such as physical health and exposure to violence may affect mental health of OVC in Cambodia. As health is of utmost importance, better healthcare services should be made easily accessible for OVC. Schools have the potential to act as a buffer against depressive symptoms. Therefore, efforts should be made to keep OVC in school and to improve the roles of school in Cambodia.

Longitudinal adherence to antiretroviral drugs for preventing mother-to-child transmission of HIV in Zambia.

BACKGROUND: Adherence to antiretroviral (ARV) drugs is essential for eliminating new pediatric infections of human immunodeficiency virus (HIV). Since the Zambian government revised the national guidelines based on option A (i.e., maternal zidovudine and infant ARV prophylaxis) of the World Health Organization's 2010 guidelines, no studies have assessed adherence to ARVs during pregnancy up to the postpartum period. This study aimed to examine adherence to ARVs and identify the associated risk factors. METHODS: A prospective cohort study was conducted in the Chongwe district from June 2011 to January 2014. Self-reported adherence to ARVs was examined during pregnancy and at one week, six weeks, and 24 weeks postpartum among 321 HIV-positive women. The probability of remaining adherent to ARVs was estimated using the Kaplan-Meier method, and the risk factors for non-adherence were identified using the Cox proportional hazard regressions--treating loss to follow-up as non-adherence. The statuses of HIV in HIV-exposed infants were assessed in January 2014. RESULTS: During the study period, 326 infants were born to HIV-positive women, 262 (80.4%) underwent HIV testing, and 11 (3.4%) had their HIV infection detected at the time that they had the latest HIV testing as of January 2014. The ARV adherence rate was 82.5% during pregnancy, 84.2% at one week postpartum, 81.5% at six weeks postpartum, and 70.5% at 24 weeks postpartum. The probability of remaining adherent to ARVs was 0.61 at day 50, 0.35 at day 100, 0.18 at day 200, and 0.06 at day 300. Attending a referral health center (HC) was a risk factor for non-adherence compared with attending rural HCs that provided HIV care/treatment (adjusted hazard ratio [aHR] 0.71, 95% confidence interval [CI] 0.57-0.88) and those that did not provide HIV care/treatment (aHR 0.58, 95% CI 0.46-0.74). A new diagnosis of HIV infection compared to a known HIV-positive status before pregnancy was another risk factor for non-adherence (aHR 1.24, 95% CI 1.03-1.50). CONCLUSIONS: Maintaining adherence to ARVs through pregnancy to the postpartum period remains a crucial challenge in Zambia. To maximize the treatment benefits, adherence to ARVs and retention in care should be improved at all health facilities.

Training Sri Lankan public health midwives on intimate partner violence: a pre- and post-intervention study.

BACKGROUND: In many developing countries, intimate partner violence (IPV) training is not available for health providers. As a pioneer among developing countries, in 2009, the Sri Lankan Ministry of Health trained a group of community health providers known as public health midwives (PHMs) on IPV. We evaluated that training program's efficacy in improving PHMs' identification and management of IPV sufferers in Kandy, Sri Lanka. METHODS: We conducted this study from August 2009 to September 2010. We used a self-administered structured questionnaire to examine the following variables among 408 PHMs: self-reported IPV practices, IPV knowledge, perceived barriers, perceived responsibility, and self-confidence in identifying and assisting IPV sufferers. We used McNemar's test to compare PHMs' pre- and post-intervention IPV practices. Using the Wilcoxon signed-rank test, we compared PHMs' pre-and post-intervention IPV knowledge, as well as their perceived barriers, responsibility, and self-confidence scores. RESULTS: The IPV training program improved PHMs' IPV practices significantly. Six months after the intervention, 98.5% (n = 402) of the 408 PHMs identified at least one IPV sufferer in the previous three months, compared to 73.3% (n = 299) in the pre-intervention (p < 0.001). At post-intervention, 96.5% (n = 387) of the PHMs discussed IPV with identified sufferers and suggested solutions; only 67.3% (n = 201) did so at the pre-intervention (p < 0.001). In addition, after the intervention, there were significant increases (p < 0.001) in the median total scores of PHMs' IPV knowledge (0.62 vs. 0.88), perceived responsibility (3.20 vs. 4.60), and self-confidence (1.81 vs. 2.75). PHMs' perceived barriers decreased from 2.43 to 1.14 (p < 0.001). CONCLUSIONS: An IPV training program for PHMs improved identification and assistance of IPV sufferers in Kandy, Sri Lanka. This training program has the potential to improve PHMs' skills in preventing IPV and supporting sufferers in other regions of Sri Lanka. Other developing countries might learn lessons from Sri Lanka's IPV training.

Application of loop analysis for evaluation of malaria control interventions.

BACKGROUND: Despite continuous efforts and recent rapid expansion in the financing and implementation of malaria control interventions, malaria still remains one of the most devastating global health issues. Even in countries that have been successful in reducing the incidence of malaria, malaria control is becoming more challenging because of the changing epidemiology of malaria and waning community participation in control interventions. In order to improve the effectiveness of interventions and to promote community understanding of the necessity of continued control efforts, there is an urgent need to develop new methodologies that examine the mechanisms by which community-based malaria interventions could reduce local malaria incidence. METHODS: This study demonstrated how the impact of community-based malaria control interventions on malaria incidence can be examined in complex systems by qualitative analysis combined with an extensive review of literature. First, sign digraphs were developed through loop analysis to analyse seven interventions: source reduction, insecticide/larvicide use, biological control, treatment with anti-malarials, insecticide-treated mosquito net/long-lasting insecticidal net, non-chemical personal protection measures, and educational intervention. Then, for each intervention, the sign digraphs and literature review were combined to analyse a variety of pathways through which the intervention can influence local malaria incidence as well as interactions between variables involved in the system. Through loop analysis it is possible to see whether increases in one variable qualitatively increases or decreases other variables or leaves them unchanged and the net effect of multiple, interacting variables. RESULTS: Qualitative analysis, specifically loop analysis, can be a useful tool to examine the impact of community-based malaria control interventions. Without relying on numerical data, the analysis was able to describe pathways through which each intervention could influence malaria incidence on the basis of the qualitative patterns of the interactions between variables in complex systems. This methodology is generalizable to various disease control interventions at different levels, and can be utilized by a variety of stakeholders such as researchers, community leaders and policy makers to better plan and evaluate their community-based disease control interventions.

Strong nutrition governance is a key to addressing nutrition transition in low and middle-income countries: review of countries' nutrition policies.

UNLABELLED: Nutrition transition necessitates low and middle-income countries (LAMICs) to scale up their efforts in addressing the burdens of undernutrition and overweight/obesity. Magnitudes of undernutrition and overweight are high in LAMICs, but no study has reviewed the existence of nutrition policies to address it. No evidence is also available on the effect of nutrition policies and governance on the undernutrition and overweight/obesity patterns in such countries. We conducted a policy review to examine the presence and associations of nutrition policies and governance with the children's nutrition statuses in LAMICs. METHODS: We reviewed nutrition policies, nutrition governance, and the trends of nutrition status from LAMICs. We retrieved data on the policies from the global database on the implementation of nutrition actions (GINA). We also retrieved data on the trends of nutrition status and nutrition governance from the nutrition landscape information system (NLiS), and on LAMICs from the World Bank database. We then analyzed the data both descriptively and by using a mixed effects model with random-intercept by country. RESULTS: Of the 139 LAMICs reviewed, only 39.6% had policies to address both undernutrition and overweight/obesity. A higher proportion of low-income countries (LICs) had policies to address undernutrition compared to that of middle-income countries (MICs) (86.1% vs. 63.1%, p = 0.002), and a low proportion of both had policy to address overweight. Having a nutrition policy that addresses undernutrition was not associated with better nutrition status outcomes. Strong nutrition governance in LAMICS was associated with low magnitudes of stunting (beta = -4.958, p = 0.015); wasting (beta = -5.418, p = 0.003); and underweight (beta = -6.452, p = 0.001). CONCLUSION: Despite high magnitudes of undernutrition and overweight/obesity in LAMICs, only about one third of them had nutrition policies to address such nutrition transition. Having strong nutrition governance may help to bring down the magnitudes of undernutrition in LAMICs.

Female community health volunteers service utilization for childhood illness- improving quality of health services only is not enough: a cross-sectional study in mid-western region, Nepal.

BACKGROUND: Female Community Health Volunteers (FCHVs) are considered service providers for major health problems at the community level in Nepal. However, few studies have been conducted about the roles of FCHVs from the users' perspective. This study sought to examine the current status of FCHV service utilization and identify the determinants of caregivers' utilization of FCHVs' health services in the mid-western region of Nepal. METHODS: This cross-sectional study targeted 446 caregivers of children under five years of age and whose children had ever fallen ill in the study village development committees (VDCs) of three districts of Nepal. Caregivers were asked about their usual health practices for childhood illness, health service utilization for childhood illness, children's health condition, satisfaction with health services, and socio-demographic status. Descriptive statistics and multiple logistic regression were used for analysis. RESULTS: Among 446 caregivers, 66.8% had never sought care from FCHVs for their children's illnesses in their lifetime, and more than 50% of them were unaware of FCHVs' services for acute respiratory infection and diarrhea. Among 316 caregivers whose child had an illness during the last seven months, 92.3% of them (n = 293) did not take their child to FCHVs. The main reasons were the lack of medicine available from them and their incompetency in providing care. Among the 446 caregivers, those who participated in a mothers' group (n = 82) were more likely to use FCHVs' services in their lifetime (AOR = 3.23, 95% CI =1.81-5.76). CONCLUSIONS: Caregivers can gain benefit by using FCHV's health services, but a majority of the caregivers did not seek care from FCHVs due to its limited quality. Raising caregivers' awareness on FCHV is equally important at community level.

Integrating child health services into malaria control services of village malaria workers in remote Cambodia: service utilization and knowledge of malaria management of caregivers.

BACKGROUND: Malaria and other communicable diseases remain major threats in developing countries. In Cambodia, village malaria workers (VMWs) have been providing malaria control services in remote villages to cope with the disease threats. In 2009, the VMW project integrated child health services into the original malaria control services. However, little has been studied about the utilization of VMWs' child health services. This study aimed to identify determinants of caregivers' VMW service utilization for childhood illness and caregivers' knowledge of malaria management. METHODS: A cross-sectional study was conducted in 36 VMW villages of Kampot and Kampong Thom provinces in July-September 2012. An equal number of VMW villages with malaria control services only (M) and those with malaria control plus child health services (M+C) were selected from each province. Using structured questionnaires, 800 caregivers of children under five and 36 VMWs, one of the two VMWs who was providing VMW services in each study village were interviewed. RESULTS: Among the caregivers, 23% in M villages and 52% in M+C villages utilized VMW services for childhood illnesses. Determinants of caregivers' utilization of VMWs in M villages included their VMWs' length of experience (AOR = 11.80, 95% confidence interval [CI] = 4.46-31.19) and VMWs' service quality (AOR = 2.04, CI = 1.01-4.11). In M+C villages, VMWs' length of experience (AOR = 2.44, CI = 1.52-3.94) and caregivers' wealth index (AOR = 0.35, CI = 0.18-0.68) were associated with VMW service utilization. Meanwhile, better service quality of VMWs (AOR = 3.21, CI = 1.34-7.66) and caregivers' literacy (AOR = 9.91, CI = 4.66-21.05) were positively associated with caregivers' knowledge of malaria management. CONCLUSIONS: VMWs' service quality and length of experience are important determinants of caregivers' utilization of VMWs' child health services and their knowledge of malaria management. Caregivers are seeking VMWs' support for childhood illnesses even if they are providing only malaria control services. This underlines the importance of scaling-up VMWs' capacity by adding child health services of good quality, which will result in improving child health status in remote Cambodia.
