Resilience and associated factors in orphaned and separated adolescents in Kenya: Understanding the relationship with care environment and HIV risks.

Orphans are at higher risk of HIV infection and several important HIV risk factors than non-orphans; however, this may be due to a combination of related social, psychological, and economic factors, as well as care environment, rather than orphan status alone. Understanding these complex relationships may aid policy makers in supporting evidence-based, cost-effective programming for this vulnerable population. This longitudinal study uses a causal effect model to examine, through decomposition, the relationship between care environment and HIV risk factors in orphaned and separated adolescents and youths (OSAY) in Uasin Gishu County, Kenya; considering resilience, social, peer, or family support, volunteering, or having one's material needs met as potential mediators. We analysed survey responses from 1105 OSAY age 10-26 living in Charitable Children's Institutions (CCI) (orphanages) and family-based care settings (FBS). Follow-up time was 7-36 months. Care in CCIs (vs. FBS) was associated with a decreased likelihood of engaging in forced, exchange, and consensual sex. Excess relative risks (ERR) attributable to the indirect pathway, mediation, or interaction were not significant in any model. Care environment was not statistically associated with differences in substance use. Our findings support the direct, unmediated, association between institutional care and HIV risk factors.

Evaluation of the association between long-lasting insecticidal nets mass distribution campaigns and child malaria in Nigeria.

BACKGROUND: Nigeria carries the greatest malaria burden among countries in the world. As part of the National Malaria Control Strategic Plan, free long-lasting insecticidal nets (LLINs) were distributed in 14 states of Nigeria through mass campaigns led by different organizations (the World Bank, UNICEF, or the Global Fund) between May 2009 and August 2010. The objective of this study was to evaluate the association between LLIN distribution campaigns and child malaria in Nigeria. METHODS: Data were from the Nigeria Malaria Indicator Survey which was carried out from October to December 2010 on a nationally representative sample of households. Participants were women aged 15-49 years and their children aged less than five years (N = 4082). The main outcome measure was the presence or absence of malaria parasites in blood samples of children (6-59 months). RESULTS: Compared with children living in communities with no campaigns, those in the campaign areas were less likely to test positive for malaria after adjusting for geographic locations, community- and individual-level characteristics including child-level use of insecticide-treated nets (ITNs). The protective effects were statistically significant for the World Bank Booster Project areas (OR = 0.18, 95% CI = 0.04-0.73) but did not reach statistical significance for other campaign areas. Results also showed that community-level wealth (OR = 0.51, 95% CI = 0.34-0.76), community-level maternal knowledge regarding malaria prevention (OR = 0.70, 95% CI = 0.50-0.97), and child-level use of ITNs (OR = 0.79, 95% CI = 0.63-0.99) were negatively associated with child malaria. CONCLUSIONS: The observed protective effects on child malaria of these campaigns (statistically significant in the World Bank Booster Project areas and non-significant in the other areas) need to be corroborated by future effectiveness studies. Results also show that improving community-level maternal knowledge through appropriate channels might be helpful in preventing child malaria in Nigeria.

Individual participant data meta-analysis of mechanical workplace risk factors and low back pain.

OBJECTIVES: We used individual participant data from multiple studies to conduct a comprehensive meta-analysis of mechanical exposures in the workplace and low back pain. METHODS: We conducted a systematic literature search and contacted an author of each study to request their individual participant data. Because outcome definitions and exposure measures were not uniform across studies, we conducted 2 substudies: (1) to identify sets of outcome definitions that could be combined in a meta-analysis and (2) to develop methods to translate mechanical exposure onto a common metric. We used generalized estimating equation regression to analyze the data. RESULTS: The odds ratios (ORs) for posture exposures ranged from 1.1 to 2.0. Force exposure ORs ranged from 1.4 to 2.1. The magnitudes of the ORs differed according to the definition of low back pain, and heterogeneity was associated with both study-level and individual-level characteristics. CONCLUSIONS: We found small to moderate ORs for the association of mechanical exposures and low back pain, although the relationships were complex. The presence of individual-level OR modifiers in such an area can be best understood by conducting a meta-analysis of individual participant data.

Choosing a survey sample when data on the population are limited: a method using Global Positioning Systems and aerial and satellite photographs.

BACKGROUND: Various methods have been proposed for sampling when data on the population are limited. However, these methods are often biased. We propose a new method to draw a population sample using Global Positioning Systems and aerial or satellite photographs. RESULTS: We randomly sampled Global Positioning System locations in designated areas. A circle was drawn around each location with radius representing 20 m. Buildings in the circle were identified from satellite photographs; one was randomly chosen. Interviewers selected one household from the building, and interviews were conducted with eligible household members. CONCLUSIONS: Participants had known selection probabilities, allowing proper estimation of parameters of interest and their variances. The approach was made possible by recent technological developments and access to satellite photographs.

Health-related quality of life of Gaza Palestinians in the aftermath of the winter 2008-09 Israeli attack on the Strip.

BACKGROUND: We document the health-related quality of life (HRQoL) of people living in the Gaza Strip 6 months after 27 December 2008 to 18 January 2009, Israeli attack. METHODS: Cross-sectional survey 6 months after the Israeli attack. Households were selected by cluster sampling in two stages: a random sample of enumeration areas (EAs) and a random sample of households within each chosen EA. One randomly chosen adult from each of 3017 households included in the survey completed the World Health Organization Quality of Life instrument, in addition to reported information on distress, insecurities and threats. RESULTS: Mean HRQoL score (range 0-100) for the physical domain was 69.7, followed by the psychological (59.8) and the environmental domain score (48.4). Predictors of lower (worse) scores for all three domains were: lower educational levels, residence in rural areas, destruction to one's private property or high levels of distress and suffering. Worse physical and psychological domain scores were reported by people who were older and those living in North Gaza governorate. Worse physical and environmental domain scores were reported by people with no one working at home, and those with worse standard of living levels. Respondents who reported suffering stated that the main causes were the ongoing siege, the latest war on the Strip and internal Palestinian factional violence. CONCLUSION: Results reveal poor HRQoL of adult Gazans compared with the results of WHO multi-country field trials and significant associations between low HRQoL and war-related factors, especially reports of distress, insecurity and suffering.

The relationships between resilience, care environment, and social-psychological factors in orphaned and separated adolescents in western Kenya.

The relationships between care environment, resilience, and social factors in orphaned and separated adolescents and youths (OSAY) in western Kenya are complex and under-studied. This study examines these relationships through the analysis of survey responses from OSAY living in Charitable Children's Institutes (CCI) and family-based care settings (FBS) in Uasin Gishu County, Kenya. The associations between 1) care environment and resilience (measured using the 14-item Resilience Scale); 2) care environment and factors thought to promote resilience (e.g. social, family, and peer support); and 3) resilience and these same resilience-promoting factors, were examined using multivariable linear and logistic regressions. This cross-sectional study included 1202 OSAY (50.4% female) aged 10-26 (mean=16; SD=3.5). The mean resilience score in CCIs was 71 (95%CI=69-73) vs. 64 (95%CI=62-66) in FBS. OSAY in CCIs had higher resilience (ß=7.67; 95%CI=5.26-10.09), social support (ß=0.26; 95%CI=0.14-0.37), and peer support (ß=0.90; 95%CI=0.64-1.17) than those in FBS. OSAY in CCIs were more likely to volunteer than those in FBS (OR=3.72; 95%CI=1.80-7.68), except in the male subgroup. Family (ß=0.42; 95%CI=0.24-0.60), social (ß=4.19; 95%CI=2.53-5.85), and peer (ß=2.13; 95%CI=1.44-2.83) relationships were positively associated with resilience in all analyses. Volunteering was positively associated with resilience (ß=5.85; 95%CI=1.51-10.19). The factor most strongly related to resilience in both fully adjusted models was peer support. This study found a strong relationship between care environment and resilience. Care environment and resilience each independently demonstrated strong relationships with peer support, social support, and participating in volunteer activities. Resilience also had a strong relationship with familial support. These data suggest that resilience can be developed through strategic supports to this vulnerable population.

Translation of mechanical exposure in the workplace into common metrics for meta-analysis: a reliability and validity study.

OBJECTIVES: We previously assessed inter-rater reliability of expert raters using six scales to estimate the intensity of literature-based mechanical exposures. The objectives of this study were to estimate the impact on the inter-rater reliability of using non-expert (NE) raters and to assess the validity of our scales. METHODS: We used 7-point scales to represent three dimensions of mechanical exposures at work: 1) trunk posture, 2) weight lifted or force exerted and 3) spinal loading. We estimated both peak and cumulative loads and called this an "interpretive translation" of exposure. A second method, "algorithmic translation", used the original units in which the exposure data was collected. These data were used to assess the inter-rater reliability and validity of the NE interpretive translation of exposure. RESULTS: The NE inter-rater reliability for the scales ranged from 0.24 to 0.46. The correlation between the means of the NE and expert ratings were >0.7. Although there was a strong relationship between the NE interpretive and the algorithmic translation, there was some evidence that the interpretive translation plateaus at higher level of exposure. CONCLUSIONS: This study supports using NE raters to estimate the intensity of literature-based mechanical exposure metrics using a common set of scales which can be applied across epidemiologic studies. We would need to average the ratings of at least five NE raters to have an acceptable level of reliability (>0.7). These metrics may be useful to quantify the relationship between workplace mechanical exposure and low back pain in a systematic review and meta-analysis.

Psychometric properties of an Arabic-language health literacy assessment scale for adolescents (HAS-A-AR) in Palestine.

OBJECTIVES: Health literacy research in Palestine is limited, and a locally validated tool for use among adolescents has been unavailable until now. Therefore, this study aimed to adapt health literacy assessment scale for adolescents (HAS-A) into Arabic language (HAS-A-AR) and Palestinian context and to investigate its psychometric properties. DESIGN: We conducted a cross-sectional household survey using a stratified random sample and household face-to-face interviews. SETTING AND PARTICIPANTS: We conducted 1200 interviews with sixth to ninth graders in the Ramallah and al-Bireh district of the West Bank, Palestine in 2017. METHODS: We translated and adapted HAS-A to be sensitive to the Palestinian context and tested its psychometric properties. We evaluated face and content validity during the back-translation process and checked for construct validity through exploratory factor analysis (EFA). We tested for internal consistency using Cronbach's alpha, MacDonald's omega test and the greatest lower bound (GLB). Furthermore, we calculated the scale's average inter-item correlation. RESULTS: EFA revealed that HAS-A-AR has a similar structure to the original HAS-A. It extracted three factors (communication, confusion and functional health literacy) whose eigenvalues were >1. Together they explained 57% of the total variance. The proportions of adolescents with high levels of communication, confusion and functional health literacy were 45%, 68% and 80%, respectively. Cronbach's alpha, MacDonald's omega and the GLB values for communication subscale were 0.87, 0.88 and 0.90, and they were 0.78, 0.77 and 0.79 for confusion subscale, while they were 0.77, 0.77 and 0.80, respectively, for functional healthy literacy subscale. The average inter-item correlation for the subscales ranged between 0.36 and 0.59. CONCLUSION: HAS-A-AR is a valid and reliable health literacy measuring instrument with appropriate psychometric properties. HAS-A-AR is currently available for use among adolescents in Palestine and the surrounding Arab countries with similar characteristics as Palestine, including language, culture and political instability.

Reliability and validity of the RS14 in orphaned and separated adolescents and youths in western Kenya.

PURPOSE: The 14-item Resilience Scale (RS14) is a tool designed to measure psychological resilience. It has been used effectively in diverse populations. However, its applicability is largely unknown for Sub-Saharan adolescent populations and completely unknown for orphaned and separated adolescents and youths (OSAY), a highly vulnerable population for whom resilience may be critical. This study assesses the RS14's psychometric properties for OSAY in Uasin Gishu County, Kenya. METHODS: Survey responses from a representative sample of 1016 OSAY (51.3% female) aged 10-25 (mean = 16; SD = 3.5) living in institutional and home-based environments in Uasin Gishu County were analyzed. The RS14's psychometric properties were assessed by examining internal consistency reliability, confirmatory factor analyses, and convergent validity using correlations between resilience and each of social support and depression. Sub-analyses were conducted by age and sex. RESULTS: Resilience scores ranged from 14-98 (mean = 66; SD = 19) with no sex-based significant difference. Resilience was higher for those aged ≥18 (mean = 69; range = 14-98) versus age <18 (mean = 65; range = 14-98). Internal consistency was good (Cronbach's α = .90). Confirmatory factor analysis indicated a 1-factor solution, though the model fit was only moderate. Resilience was positively correlated with social support in all ages (.22; p < .001) and negatively correlated with depression in individuals age <18 (-.22; p < .001). The relationship between resilience and depression in individuals age ≥18 was statistically significant only in females (-.17; p = .026). CONCLUSION: This study demonstrates reasonable evidence that the RS14 is both valid and reliable for measuring psychological resilience in the population of OSAY in western Kenya.

Screening for intimate partner violence in health care settings: a randomized trial.

CONTEXT: Whether intimate partner violence (IPV) screening reduces violence or improves health outcomes for women is unknown. OBJECTIVE: To determine the effectiveness of IPV screening and communication of positive results to clinicians. DESIGN, SETTING, AND PARTICIPANTS: Randomized controlled trial conducted in 11 emergency departments, 12 family practices, and 3 obstetrics/gynecology clinics in Ontario, Canada, among 6743 English-speaking female patients aged 18 to 64 years who presented between July 2005 and December 2006, could be seen individually, and were well enough to participate. INTERVENTION: Women in the screened group (n=3271) self-completed the Woman Abuse Screening Tool (WAST); if a woman screened positive, this information was given to her clinician before the health care visit. Subsequent discussions and/or referrals were at the discretion of the treating clinician. The nonscreened group (n=3472) self-completed the WAST and other measures after their visit. MAIN OUTCOME MEASURES: Women disclosing past-year IPV were interviewed at baseline and every 6 months until 18 months regarding IPV reexposure and quality of life (primary outcomes), as well as several health outcomes and potential harms of screening. RESULTS: Participant loss to follow-up was high: 43% (148/347) of screened women and 41% (148/360) of nonscreened women. At 18 months (n = 411), observed recurrence of IPV among screened vs nonscreened women was 46% vs 53% (modeled odds ratio, 0.82; 95% confidence interval, 0.32-2.12). Screened vs nonscreened women exhibited about a 0.2-SD greater improvement in quality-of-life scores (modeled score difference at 18 months, 3.74; 95% confidence interval, 0.47-7.00). When multiple imputation was used to account for sample loss, differences between groups were reduced and quality-of-life differences were no longer significant. Screened women reported no harms of screening. CONCLUSIONS: Although sample attrition urges cautious interpretation, the results of this trial do not provide sufficient evidence to support IPV screening in health care settings. Evaluation of services for women after identification of IPV remains a priority. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00182468.

Low-back pain definitions in occupational studies were categorized for a meta-analysis using Delphi consensus methods.

OBJECTIVE: To determine which literature-based definitions of low back pain (LBP) could be combined to produce sufficiently similar sets for use in a meta-analysis. STUDY DESIGN AND SETTING: A group of six international experts participated in an e-mail-administered Delphi process. Literature-based LBP definitions were preliminarily classified into 14 sets within four outcome types: pathology, symptoms and care-seeking, functional limitations, and participation. Experts independently rated their level of agreement that each outcome definition belonged in its assigned set using a seven-point Likert scale. After each round, results were synthesized and revised classifications were fed back to the experts who were asked to consider them before rerating the outcome definitions. RESULTS: The experts completed three Delphi rounds and reached consensus on the categorization of 115/119 (97%) of the outcome definitions. There were 20 final sets of outcomes identified: three sets of pathology outcomes, two sets each of functional limitation and participation outcomes, and 13 sets of symptom and care-seeking outcomes. CONCLUSIONS: In a research area that currently lacks uniformly accepted definitions of outcomes, we successfully used a Delphi consensus process to reach substantial agreement on combinable LBP outcomes that would be combinable for a meta-analysis.

Work organization and its effects on the health of Chinese workers with English as a second language: a qualitative approach.

Work organization consists of three contexts: (a) the external context/factors, (b) the organizational context/practices, and, (c) the work context/process. The investigation of work organization may lead to more effective prevention and intervention for work-related injury and illness. Studies have suggested that workers with limited English proficiency may be more prone to work-related injury and illness. The purposes of this qualitative phenomenological study were to gain a better understanding of the meaning of work organization to Chinese workers with English as a second language (ESL) and to explore their lived experiences on how work organization affects their health. Ten in-depth face to face interviews were conducted with Chinese ESL workers (5 males and 5 females; ages ranged from 22 to 41 years) who were employed in English-speaking workplaces in the Greater Toronto Area, Ontario, Canada. Interviews were translated and transcribed before importing them into NUD*IST, a qualitative data management software program. The transcripts were then coded, and categories were developed based on the codes. Subsequently, eight themes were identified from the categories. Work organization was perceived by Chinese ESL workers to be at an impersonal and distant level. Workers also identified work organization related issues (i.e., employers' priority, communication, work culture, job autonomy, recognition, and individual characteristics) as factors affecting their health at workplaces. However, these workers commonly expressed resignation towards their own health. Workplaces, especially those with Chinese ESL workers, need to place greater emphasis on implementing effective health and safety approaches to maximize the health of these workers.

Effectiveness of home visitation by public-health nurses in prevention of the recurrence of child physical abuse and neglect: a randomised controlled trial.

BACKGROUND: Recurrence of child maltreatment is a major problem, yet little is known about approaches to reduce this risk in families referred to child protection agencies. Since home visitation by nurses for disadvantaged first-time mothers has proven effective in prevention of child abuse and neglect, we aimed to investigate whether this approach might reduce recidivism. METHODS: We enrolled in a randomised controlled trial 163 families with a history of one index child being exposed to physical abuse or neglect to compare standard treatment with a programme of home visitation by nurses in addition to standard treatment. The main outcome was recurrence of child physical abuse and neglect based on a standardised review of child protection records. Analysis was by intention to treat. FINDINGS: At 3-years' follow-up, records were available for 160 of 163 (98%) families randomised. 139 (85%) completed follow-up. Recurrence of child physical abuse (31 [43%] in the control group vs 29 [33%] in the intervention group) and neglect (37 [51%] vs 41 [47%]) did not differ between groups. However, hospital records showed significantly higher recurrence of either physical abuse or neglect in the intervention group than in the control group (21 [24%] vs 8 [11%]). There were no differences between groups for the other secondary outcome measures. INTERPRETATION: Despite the positive results of home visitation by nurses as an early prevention strategy, this visit-based strategy does not seem to be effective in prevention of recidivism of physical abuse and neglect in families associated with the child protection system. Much more effort needs to be directed towards prevention before a pattern of abuse or neglect is established in a family.

Changes in job stressors in the Canadian working population.

OBJECTIVES: To determine the changes in levels of work stressors in a nationally representative sample of Canadian workers from 1994/95 to 2000/01. METHODS: We compared responses for an abbreviated version of the Job Content Questionnaire in two waves of the National Population Health Survey (NPHS). Other items and scales related to work and health were also analyzed. Data were transformed to range from 0 to 10. Comparisons of the 2000/01 data were also made with the Canadian Community Health Survey (CCHS) conducted in 2000. RESULTS: There were only very small absolute differences between NPHS 2000/01 data and CCHS 2000 data. The NPHS comparison from 1994/95 to 2000/01 showed an increase in job security (change in means = 0.49, 95% CI 0.39 to 0.58) and a decrease in job physical demands (change in means = 0.45, 95% CI 0.35 to 0.54). Other changes in work characteristics were small in absolute value. The combined "overall work stressors" index dropped by 0.12 (95% CI 0.08 to 0.15). CONCLUSIONS: Levels of work stressors did not increase over the period. Some subscales showed an improvement.

Interpreting angina: symptoms along a gender continuum.

BACKGROUND: 'Typical' angina is often used to describe symptoms common among men, while 'atypical' angina is used to describe symptoms common among women, despite a higher prevalence of angina among women. This discrepancy is a source of controversy in cardiac care among women. OBJECTIVES: To redefine angina by (1) qualitatively comparing angina symptoms and experiences in women and men and (2) to propose a more meaningful construct of angina that integrates a more gender-centred approach. METHODS: Patients were recruited between July and December 2010 from a tertiary cardiac care centre and interviewed immediately prior to their first angiogram. Symptoms were explored through in-depth semi-structured interviews, transcribed verbatim and analysed concurrently using a modified grounded theory approach. Angiographically significant disease was assessed at ≥70% stenosis of a major epicardial vessel. RESULTS: Among 31 total patients, 13 men and 14 women had angiograpically significant CAD. Patients describe angina symptoms according to 6 symptomatic subthemes that array along a 'gender continuum'. Gender-specific symptoms are anchored at each end of the continuum. At the centre of the continuum, are a remarkably large number of symptoms commonly expressed by both men and women. CONCLUSIONS: The 'gender continuum' offers new insights into angina experiences of angiography candidates. Notably, there is more overlap of shared experiences between men and women than conventionally thought. The gender continuum can help researchers and clinicians contextualise patient symptom reports, avoiding the conventional 'typical' versus 'atypical' distinction that can misrepresent gendered angina experiences.

Correlates of employees' perceptions of a healthy work environment.

PURPOSE: This study analyzed correlates of workers' perceptions of the extent to which their work environment is healthy and how these perceptions influence job satisfaction, employee commitment, workplace morale, absenteeism, and intent to quit. DESIGN: One-time cross-sectional telephone survey. SETTING: Canadian employees in 2000. SUBJECTS: A randomly chosen, nationally representative sample of 2500 employed respondents, using a household sampling frame. The response rate was 39.2%. Self-employed individuals were excluded, leaving a subsample of 2112 respondents. MEASURES: The dependent variable was the response to the item, "The work environment is healthy" (5-point strongly agree-strongly disagree Likert scale). Independent variables used in bivariate and ordinary least-squares regression analyses included sociodemographic characteristics, employment status, organizational characteristics, and scales that measured job demands, intrinsic rewards, extrinsic rewards, communication/social support, employee influence, and job resources. Perceptions of a healthy work environment were related to job satisfaction, commitment, morale (measured on a 5-point scale), number of self-reported absenteeism days in the past 12 months, and whether or not the respondent had looked for a job with another employer in the past 12 months. RESULTS: The strongest correlate of a healthy work environment was a scale of good communication and social support (beta = .27). The next strongest was a job demands scale (beta = -.15.) Employees in self-rated healthier work environments had significantly (p < 0.01) higher job satisfaction, commitment and morale, and lower absenteeism and intent to quit. CONCLUSIONS: The study supports a comprehensive model of workplace health that targets working conditions, work relationships, and workplace organization for health promotion interventions.
