Who buys nets? Factors associated with ownership and use of purchased mosquito nets in sub-Saharan Africa.

BACKGROUND: Public sector strategies to promote insecticide-treated net (ITN) access have resulted in increased ITN ownership across sub-Saharan Africa. However, the current status of the private sector distribution channel for nets has not been fully explored. This multi-country study explored the prevalence of net purchases and the characteristics of households that had purchased nets and used such nets in sub-Saharan Africa. METHODS: Data from recent Malaria Indicator Survey (MIS) or Demographic and Health Survey (DHS) in 16 countries were analysed to explore the prevalence of purchased nets. Purchased nets were defined as nets obtained from shops/markets or pharmacies. Additional sub-analysis of factors associated with ownership and use of purchased nets was conducted in seven countries with over 10% of nets reported as purchased. Key outcomes included: prevalence of purchased nets out of all nets, household ownership of a purchased net, and whether a purchased net was used the previous night. Analytical methods included country level tests of association and multivariable logistic regressions. RESULTS: Among all nets, the proportion of purchased nets in the study countries ranged from 0.8 to 32.7% and most (median = 77%) of these purchased nets were ITNs. Although the private nets are presumed to be from the retail, non-public sector, the prevalence of treated purchased nets suggests that some purchased nets may be "leaked" ITNs from public sector distributions, and thus, may be an informal sector rather than part of the formal "private sector". Urban, wealthier households as well as those with educated heads were more likely to own purchased nets. Use of such nets was, however, lower in wealthier households. In addition, net use was higher in households owning insufficient nets for their family size, and when the nets were newer than 24 months. CONCLUSION: The formal and informal private sector have played a role in bolstering net access rates in some settings. Study findings can help relevant malaria control stakeholders gain insight on the contribution of purchased nets on their overall ITN strategy, identify potential target populations for private sector nets as well as inform the design and distribution of private sector insecticide-treated nets that appeal to their target groups.

Age and gender trends in insecticide-treated net use in sub-Saharan Africa: a multi-country analysis.

BACKGROUND: The degree to which insecticide-treated net (ITN) supply accounts for age and gender disparities in ITN use among household members is unknown. This study explores the role of household ITN supply in the variation in ITN use among household members in sub-Saharan Africa. METHODS: Data was from Malaria Indicator Surveys or Demographic and Health Surveys collected between 2011 and 2016 from 29 countries in sub-Saharan Africa. The main outcome was ITN use the previous night. Other key variables included ITN supply (nets/household members), age and gender of household members. Analytical methods included logistic regressions and meta-regression. RESULTS: Across countries, the median (range) of the percentage of households with enough ITNs was 30.7% (8.5-62.0%). Crude analysis showed a sinusoidal pattern in ITN use across age groups of household members, peaking at 0-4 years and again around 30-40 years and dipping among people between 5-14 and 50+ years. This sinusoidal pattern was more pronounced in households with not enough ITNs compared to those with enough ITNs. ITN use tended to be higher in females than males in households with not enough ITNs while use was comparable among females and males in households with enough ITNs. After adjusting for wealth quintile, residence and region, among households with not enough ITNs in all countries, the odds of ITN use were consistently higher among children under 5 years and non-pregnant women 15-49 years. Meta-regressions showed that across all countries, the mean adjusted odds ratio (aOR) of ITN use among children under 5 years, pregnant and non-pregnant women aged 15-49 years and people 50 years and above was significantly higher than among men aged 15-49 years. Among these household members, the relationship was attenuated when there were enough ITNs in the household (dropping 0.26-0.59 points) after adjusting for geographical zone, household ITN supply, population ITN access, and ITN use:access ratio. There was no significant difference in mean aOR of ITN use among school-aged children compared to men aged 15-49 years, regardless of household ITN supply. CONCLUSIONS: This study demonstrated that having enough ITNs in the household increases level of use and decreases existing disparities between age and gender groups. ITN distribution via mass campaigns and continuous distribution channels should be enhanced as needed to ensure that households have enough ITNs for all members, including men and school-aged children.

Measuring Women's Covert Use of Modern Contraception in Cross-Sectional Surveys.

A proportion of women in couples use contraception without their partners' knowledge. There are two principal ways to measure this covert use in cross-sectional surveys like the Demographic and Health Surveys (DHS). First is a direct question, "Does your husband/partner know that you are using a method of family planning?" Second is an indirect method: the reports of both partners to the question on contraceptive use are matched, and if the woman reports a modern contraceptive method and the male partner reports nonuse, her use is considered covert. For 21 DHS surveys for which both estimates could be made, there are large discrepancies between the two. We found that a proxy variable-responses to the question, "Would you say that using contraception is mainly your decision, mainly your husband's/partner's decision, or did you both decide together?"-has high sensitivity and specificity for classifying those in the open category for both methods and those in the covert category for both methods. Recommendations are that the direct question be reinstated in the DHS and that the indirect method not be used by itself but in conjunction with the decision-making variable.

Designing and collecting data for a longitudinal study: the Sleman Health and Demographic Surveillance System (HDSS).

BACKGROUND: This paper describes the methodological considerations of developing an urban Health and Demographic Surveillance System (HDSS), in the Sleman District of Yogyakarta, Indonesia. METHODS: 1) The Sleman District was selected because it is mostly an urban area. 2) The minimum sample size was calculated to measure infant mortality as the key variable and resulted in a sample of 4942 households. A two-stage cluster sampling procedure with probability proportionate to size was applied; first, 216 Censuses Blocks (CBs) were selected, and second, 25 households in each CB were selected. 3) A baseline survey was started in 2015, and collected data on demographic and economic characteristics and verbal autopsy (VA); the 2nd cycle collected updated demographic data, VA, type of morbidity (communicable and non-communicable diseases, disability and injury) and health access. 4) The data were collected at a home visit through a Computer-Assisted Personal Interview (CAPI) on a tablet device, and the data were transferred to the server through the Internet. 5) The quality control consisted of spot-checks of 5% of interviews to control for adherence to the protocol, re-checks to ensure the validity of the interview, and computer-based data cleaning. 6) A utilization system was designed for policy-makers (government) and researchers. RESULTS: In total, 5147 households participated in the baseline assessment in 2015, and 4996 households participated in the second cycle in 2016 (97.0% response rate). CONCLUSIONS: Development of an urban HDSS is possible and is beneficial in providing data complementary to the existing demographic and health information system at local, national and global levels.

National Needs of Family Planning Among US Men Aged 15 to 44 Years.

OBJECTIVES: To estimate national need for family planning services among men in the United States according to background characteristics, access to care, receipt of services, and contraception use. METHODS: We used weighted data from the 2006-2010 National Survey of Family Growth to estimate the percentage of men aged 15 to 44 years (n = 10 395) in need of family planning, based on sexual behavior, fecundity, and not trying to get pregnant with his partner. RESULTS: Overall, 60% of men were in need of family planning, defined as those who ever had vaginal sex, were fecund, and had fecund partner(s) who were not trying to get pregnant with partner or partner(s) were not currently pregnant. The greatest need was among young and unmarried men. Most men in need of family planning had access to care, but few reported receiving family planning services (< 19%), consistently using condoms (26%), or having partners consistently using contraception (41%). CONCLUSIONS: The need for engaging men aged 15 to 44 years in family planning education and care is substantial and largely unmet despite national public health priorities to include men in reducing unintended pregnancies.

Men Aged 15-44 in Need of Preconception Care.

OBJECTIVES: Preconception care for men focuses on prevention strategies implemented prior to conception of a first or subsequent pregnancy to improve pregnancy and infant outcomes. Little is known about U.S. men in need of preconception care. This analysis describes the proportion of men in need of preconception care and associations of these needs by background characteristics, related health conditions, access to care and receipt of services. METHODS: Data from men aged 15-44 in the National Survey of Family Growth 2006-2010 were analyzed to describe men in need of preconception care, based on future childbearing intentions and self and partner fecundity status (among sexually experienced only), and associated factors with these needs using weighted bivariate analyses. RESULTS: About 60 % of men are in need of preconception care. Higher prevalence of being in need was observed among men aged 15-29 than older; living in urban than non-urban settings; in school than not in school regardless of working status; not in a coresidential union than married or cohabiting; who were recent immigrants than U.S. born; and reporting never having had a child than ≥1 child(ren). Men in need were overweight/obese (56 %), ever binge drank in the last year (58 %), and have high STI risk (21 %). The majority of men in need reported access to care in the last year (>70 %), but few reported receipt of services including STD/HIV testing (<20 %) or counseling (<11 %). CONCLUSIONS FOR PRACTICE: Findings from this analysis have implications for promoting preconception care among U.S. men.

Body Satisfaction in Early Adolescence: A Multisite Comparison.

PURPOSE: This study assesses the relationship between unequal gender perceptions, socioecological factors, and body satisfaction among early adolescents in six urban poor settings in four countries. METHODS: A cross-sectional study, part of the Global Early Adolescent Study, was conducted in Shanghai, China; Cuenca, Ecuador; Kinshasa, DRC; and three cities in Indonesia: Denpasar, Semarang, and Bandar Lampung. Bivariate and multiple linear regressions were conducted to assess the relationships between body satisfaction, perceptions of gender norms, and socioecological factors. A final sample of 7840 respondents aged between 10 and 14 years were included in the analysis. RESULTS: Adolescents who endorsed more traditional sex roles and traits were more likely to be satisfied with their bodies in Kinshasa and Indonesia, while only endorsement of GST was associated with body satisfaction in Shanghai. Individual factors related to body satisfaction varied by site and included perceived health status, perception of body weight, height, and growth rate. Family and neighborhood factors related to increased body satisfaction varied by site and sex and included closeness to parents, parental communication, discussing bodily changes with anyone, parental awareness, and perception of neighborhood. CONCLUSION: The results highlight the association between gender norms and social factors at individual, family, and neighborhood levels with body satisfaction. While associations differ significantly by site and sex, namely in perception of body weight and height, there exists commonalities that suggest body satisfaction, gender norms, and social context are intertwined.

Understanding the Relationship Between Adverse Childhood Experiences, Peer-Violence Perpetration, and Gender Norms Among Very Young Adolescents in Indonesia: A Cross-Sectional Study.

PURPOSE: This study assesses the role of gender norms on the relationship between adverse childhood experiences (ACEs) and peer-violence perpetration among very young adolescents in three urban poor cities of Indonesia. METHODS: A cross-sectional study was conducted in Bandar Lampung, Denpasar, and Semarang in Indonesia. A total of 2,974 participants (boys: 44.79%, girls: 55.21%) between 10 and 14 years were included in the analysis. Logistic regression, mediation, and moderation analyses were conducted stratified by sex. RESULTS: Risk factors of peer-violence perpetration among boys and girls included three (boys: adjusted odds ratio [aOR] 2.51, 95% confidence interval [CI] 1.32-4.75; girls: aOR 1.82, 95% CI .95-3.52) and four or more (boys: aOR 6.75, 95% CI 3.86-11.80; girls: aOR 5.37, 95% CI 3.07-9.37) history of ACE. Risk factors of peer-violence perpetration among boys included having inequitable sexual double standard (SDS) indices (aOR 1.46, 95% CI 1.09-1.95). SDS measures the perception boys are rewarded for romantic relationship engagement, whereas girls are stigmatized or disadvantaged for the experience. Other risk factors included lifetime tobacco use among boys and girls and lifetime alcohol use among boys. Protective factors included parental closeness among girls. CONCLUSIONS: Based on the research in three Indonesian communities, this study demonstrates that boys are disproportionately exposed to adversities including history of ACE, inequitable SDS, lifetime alcohol use and tobacco use in comparison to girls. Programs targeting ACE and gender norms which engage boys, girls, and families are more likely to be successful in reducing peer-violence perpetration and promoting gender equitable norms.

Determining the Cause of Death: Mortality Surveillance Using Verbal Autopsy in Indonesia.

In the absence of a vital registration and health information systems, Indonesia does not have complete, accurate, and continuous data to summarize the mortality statistics of the population, nor determine the exact cause of death. Verbal autopsies performed in a community-based mortality surveillance have been used to provide information on the cause of deaths in such context. However, physician review of verbal autopsy can be expensive, time-consuming, and give inconsistent results, raising concern about its reliability. We used the Purworejo Health and Demographic Surveillance System's (HDSS) mortality data collected between 2000 and 2002 and assigned causes of death for all age groups using Interpreting Verbal Autopsy-4, analytic software that applies a probabilistic model. A total of 1,999 deaths were identified among 55,581 individuals surveyed in 14,409 households; 830 deaths were able to be recorded using the standardized World Health Organization (WHO) verbal autopsy questionnaire. We calculated the proportion of different causes of death and its incidence rate (IR) ratios with 95% confidence interval (CI) to compare the IR per person-years-observation (PYO). The IR of stroke was 126.7 per 100,000 PYO (95% CI: 109.7, 143.7); acute respiratory infection including pneumonia was 70.8 per 100,000 PYO (95% CI: 58.1, 83.5); and the IR of other and unspecified cardiac diseases was 57.7 per 100,000 PYO (95% CI: 46.2, 69.2). Stroke was indicated as the leading cause of death among elderly people aged 50 years and above. Meanwhile, pneumonia as a communicable disease was found to be the most common cause of death among both 0-14-year-old children and elderly people.
