ObjectiveTo understand the gender-specific factors that uniquely contribute to successful ageing in a US population of men and women, 57–85 years of age. This was achieved through the examination of the correlates of subjective well-being defined by health-related quality of life (HRQoL), across several biological and psychosocial determinants of health.DesignCross-sectional study.SettingThe National Social Life, Health and Ageing Project (NSHAP), 2010–2011 a representative sample of the US population.Participants3377 adults aged 57–85 (1538 men, 1839 women) from the NSHAP.Main outcome measuresThe biopsychosocial factors of biological/physiological function, symptom status, functional status, general health perceptions and HRQoL happiness.MethodHRQoL was measured using the NSHAP wave 2 multistage, stratified area probability sample of US households (n=3377). Variable selection was guided by the Wilson and Cleary model (WCM) that classifies health outcomes at five main levels and characteristics.ResultsOur findings indicate differences in biopsychosocial factors comprised in the WCM and their relative importance and unique impact on HRQoL by gender. Women reported significantly lower HRQoL than men (t=3.5, df=3366). The most significant contributors to HRQoL in women were mental health (B=0.31; 0.22, 0.39), loneliness (B=−0.26; −0.35, –0.17), urinary incontinence (B=−0.22; −0.40, –0.05) and support from spouse/partner (B=0.27; 0.10, 0.43) and family B=0.12; 0.03, 0.20). Men indicated mental health (B=0.21; 0.14, 0.29), physical health (B=0.17; 0.10, 0.23), functional difficulties (B=0.38; 0.10, 0.65), loneliness (B=−0.20; −0.26, –0.12), depression (B=−0.36; −0.58, –0.15) and support from friends (B=0.06; 0.10, 0.11) as significant contributors. Those with greater social support had better HRQoL (F=4.22, df=4). Lack of companionship and reliance on spouse/partner were significant HRQoL contributors in both groups.ConclusionOur findings offer insight into ageing, gender and subjective well-being. The results provide an opportunity to identify biopsychosocial factors to inform interventions to support successful ageing.

Background Approximately 70% of Kenya’s population is at risk for malaria. The core vector control methods in Kenya are insecticide-treated mosquito nets (ITNs) and indoor residual spraying, with supplementary larval source management. In 2015, 21% of ITNs were accessed through the private retail sector. Despite the private sector role in supplying mosquito control products (MCPs), there is little evidence on the availability, sales trends, and consumer preferences for MCPs other than ITNs. This study, a component of a larger research programme focused on evaluating a spatial repellent intervention class for mosquito-borne disease control, addressed this evidence gap on the role of the private sector in supplying MCPs. Methods A cross-sectional survey was deployed in a range of retail outlets in Busia County to characterize MCP availability, sales trends, and distribution channels. The questionnaire included 32 closed-ended and four open-ended questions with short answer responses. Descriptive analysis of frequency counts and percentages was carried out to glean insights about commercially available MCPs and the weighted average rank was used to determine consumer preferences for MCPs. Open-ended data was analysed thematically. Results Retail outlets that stocked MCPs commonly stocked mosquito coils (73.0%), topical repellents (38.1%), aerosol insecticide sprays (23.8%) and ITNs (14.3%). Overall, retailers reported the profits from selling MCPs were adequate and they overwhelmingly planned to continue stocking the products. Of respondents who stocked MCPs, 96.8% responded that sales increased during long rains and 36.5% that sales also surged during short rains. ITNs and baby-size nets were often delivered by the wholesaler. Retailers of aerosol sprays, mosquito coils, and topical repellents either collected stock from the wholesaler or products were delivered to them. Other commercially available MCPs included insecticide incense sticks, electric mosquito strikers, insecticide soaps, electrically heated insecticide mats, and electric insecticide emanators, indicating a well-established market. Conclusions The wide range of MCPs in local retail outlets within the study area suggests the need and demand for mosquito control tools, in addition to ITNs, that are affordable, easy to use and effective. The presence of a wide range of MCPs, is a promising sign for the introduction of a spatial repellent intervention class of products that meets consumer needs and preferences.

BackgroundThe feminization and ethnic diversification of HIV infection, has resulted in a call for gender- and culture-specific prevention strategies for at-risk groups including Latinos in the United States. The steadily changing demographic profile of the AIDS epidemic challenges prevention strategies to remain relevant and up-to-date, particularly in populations of women midlife and older where an understanding of risk remains under explored. As the CDC requests country-specific HIV risk profiles for Latino communities in the US, understanding the socio-economic, behavioral and personal risk reasons of HIV risk for older Dominican women is critical for prevention.MethodsWe conducted focus group discussions informed by the Theory of Gender and Power (TGP). The three constructs of the TGP: 1) Affective influences/social norms; 2) Gender-specific norms and.3) Power and Authority guided the thematic analysis and identified themes that described the socio-cultural and contextual reasons that that contribute to perceptions of HIV risk.ResultsSixty Dominican American women ages 57–73 participated in our focus group discussions. Sexual Division of Labour: 1) Economic Dependence; 2) Financial Need and 3) Education and Empowerment. Sexual Division of Power: 4) HIV Risk and 5) Relationship Dynamics. Cathexis: Affective Influences/Social Norms: 6) HIV/AIDS Knowledge and 7) Prevention and Testing. Importantly, participants were concerned about partner fidelity when visiting the Dominican Republic, as the country accounts for the second highest HIV rates in the Caribbean.ConclusionsOur results confirm previous findings about perceptions of HIV risk and provide additional insight into aging-related aspects of HIV risk for Latino women midlife and older.

Background An estimated 1.5 billion malaria cases and 7.6 million malaria deaths have been averted globally since 2000; long-lasting insecticidal nets (LLINs) have contributed an estimated 68% of this reduction. Insufficient funding at the international and domestic levels poses a significant threat to future progress and there is growing emphasis on the need for enhanced domestic resource mobilization. The Private Sector Malaria Prevention (PSMP) project was a 3-year intervention to catalyse private sector investment in malaria prevention in Ghana. Methods To assess value for money of the intervention, non-donor expenditure in the 5 years post-project catalysed by the initial donor investment was predicted. Non-donor expenditure catalysed by this investment included: workplace partner costs of malaria prevention activities; household costs in purchasing LLINs from retail outlets; domestic resource mobilization (public sector financing and private investors). Annual ratios of projected non-donor expenditure to annualized donor costs were calculated for the 5 years post-project. Alternative scenarios were constructed to explore uncertainty around future consequences of the intervention. Results The total donor financial cost of the 3-year PSMP project was USD 4,418,996. The average annual economic donor cost per LLIN distributed through retail sector and workplace partners was USD 21.17 and USD 7.55, respectively. Taking a 5-year post-project time horizon, the annualized donor investment costs were USD 735,805. In the best-case scenario, each USD of annualized donor investment led to USD 4.82 in annual projected non-donor expenditure by the fifth-year post-project. With increasingly conservative assumptions around the project consequences, this ratio decreased to 3.58, 2.16, 1.07 and 0.93 in the “very good”, “good”, “poor” and “worst” case scenarios, respectively. This suggests that in all but the worst-case scenario, donor investment would be exceeded by the non-donor expenditure it catalysed. Conclusions The unit cost per net delivered was high, reflecting considerable initial investment costs and relatively low volumes of LLINs sold during the short duration of the project. However, taking a longer time horizon and broader perspective on the consequences of this complex catalytic intervention suggests that considerable domestic resources for malaria control could be mobilized, exceeding the value of the initial donor investment.
