Economic vulnerabilities, mental health, and coping strategies among Tanzanian youth during COVID-19.

BACKGROUND: The COVID-19 pandemic has exacerbated struggles for youth living in poor households. Youth in rural Tanzania are particularly vulnerable given widespread poverty, lack of formal sector employment opportunities, and health risks. We examine influences of the pandemic on economic insecurity and mental health and explore the coping strategies employed by youth and their households. METHODS: We conducted mixed-method data collection with youth (N = 760 quantitative and N = 44 qualitative interviews) and households (n = 542) via mobile phone among a sub-set of a cohort from an on-going longitudinal sample in two rural regions in Tanzania. In addition to phone interviews, we collected data bi-weekly via SMS messaging. We present mixed-methods, descriptive analysis of the outcomes and longitudinally compare quantitative outcomes pre- and post-COVID-19, within the same individuals. RESULTS: Adverse economic impacts were most salient, and to cope, youth engaged in more labor and domestic chores. Compared to prior the COVID-19 pandemic, youth reported spending more time caring for elderly or sick household members and gathering firewood or nuts. CONCLUSIONS: These findings underscore the potential opportunity to promote policies and programs which address risks youth face. Recommended measures include expansion and adaptation of social protection policies, strengthened food and nutrition surveillance and referral systems, and scaling up community-based mental health programming.

Climate distress, climate-sensitive risk factors, and mental health among Tanzanian youth: a cross-sectional study.

BACKGROUND: Climate change threatens youth mental health through multiple mechanisms, yet empirical studies typically focus on single pathways. We explored feelings of distress over climate change among Tanzanian youth, considering associations with climate change awareness and climate-sensitive risk factors, and assessed how these factors relate to mental health. METHODS: Tanzanian youth (aged 18-23 years) from a cluster randomised controlled trial in Mbeya and Iringa regions of Tanzania were interviewed between Jan 25, and March 3, 2021, and included in this cross-sectional study. A threshold of at least 10 on the ten-item Centre for Epidemiological Studies Depression Scale was used to classify symptom severity indicative of depression. Regardless of climate change awareness, respondents were asked about their feelings of distress on climate change using inclusive language (changing weather patterns or changing seasons). We estimated rate differences in climate change distress (slight or moderate or extreme vs none) by youth characteristics, extent of climate awareness, and climate-sensitive livelihoods (eg, agriculture, tending livestock) and climate-sensitive living conditions (eg, food or water insecurity), using generalised linear models. We compared depression prevalence by extent of climate change distress and climate-sensitive living conditions. FINDINGS: Among 2053 youth (1123 [55%] were male and 930 [45%] were female) included in this analysis, 946 (46%) had reported any distress about climate change. Distress was higher among female, more educated, more religious, older youth, and those working in extreme temperatures. Adjusting for climate awareness-a factor strongly associated with climate distress-helped to explain some of these associations. Depression was 23 percentage points (95% CI 17-28) higher among youth who had severe water insecurity than those who did not. Similarly, youth who had severe food insecurity had 23 percentage points higher depression (95% CI 17-28) compared with those who did not. Those reporting climate change distress also had worse mental health-extremely distressed youth had 18 percentage points (95% CI 6-30) higher depression than those reporting none. INTERPRETATION: Living in conditions worsened by climate change and feeling distressed over climate change have mental health implications among young people from low-resource settings, indicating that climate change can impact youth mental health through multiple pathways.

The influence of gender-equitable attitudes on sexual behaviour among unmarried adolescents in rural Tanzania: a longitudinal study.

PLAIN LANGUAGE STATEMENT: Gender norms that centre men and disadvantage women create gender inequality, which can lead to risky sexual behaviour. This study examined how both community and individual attitudes toward gender norms influenced risky sexual behaviour in adolescents, and whether that influence was different between males and females. We found that higher gender-equitable attitudes were linked to increased odds of HIV testing in the last 12 months, and decreased odds of engaging in a sexual relationship with a much older partner. Individual high gender-equitable attitudes among girls were also linked to higher odds of them using condoms and contraceptives. Gender-equitable attitudes did not seem to influence early sexual debut, engagement in transactional sex, having multiple sexual partners at the same time, or the number of sexual partners a participant had in the last 12 months. Based on these findings, programming designed to increase gender-equitable attitudes might be helpful in increasing HIV testing and condom and contraceptive use, but it needs to involve the entire community, not just individual boys and girls.

Impact of community-based health insurance on health services utilisation among vulnerable households in Amhara region, Ethiopia.

BACKGROUND: Ethiopia piloted community-based health insurance in 2011, and as of 2019, the programme was operating in 770 districts nationwide, covering approximately 7 million households. Enrolment in participating districts reached 50%, holding promise to achieve the goal of Universal Health Coverage in the country. Despite the government's efforts to expand community-based health insurance to all districts, evidence is lacking on how enrolment in the programme nudges health seeking behaviour among the most vulnerable rural households. This study aims to examine the effect of community-based health insurance enrolment among the most vulnerable and extremely poor households participating in Ethiopia's Productive Safety Net Programme on the utilisation of healthcare services in the Amhara region. METHODS: Data for this study came from Amhara pilot integrated safety net programme baseline survey in Ethiopia and were collected between December 2018 and February 2019 from 5,398 households. We used propensity score matching method to estimate the impacts of enrolment in community-based health insurance on outpatient, maternal, and child preventive and curative healthcare services utilisation. RESULTS: Results show that membership in community-based health insurance increases the probabilities of visiting health facilities for curative care in the past month by 8.2 percentage points (95% CI 5.3 to 11.1), seeking care from a health professional by 8.4 percentage points (95% CI 5.5 to 11.3), and visiting a health facility to seek any medical assistance for illness and check-ups in the past 12 months by 13.9 percentage points (95% CI 10.5 to 17.4). Insurance also increases the annual household per capita health facility visits by 0.84 (95% CI 0.64 to 1.04). However, we find no significant effects of community-based health insurance membership on utilisation of maternal and child healthcare services. CONCLUSIONS: Findings that community-based health insurance increased outpatient services utilisation implies that it could also contribute towards universal health coverage and health equity in rural and informal sectors. The absence of significant effects on maternal and child healthcare services may be due to the free availability of such services for everyone at the public health facilities, regardless of insurance membership. Outpatient services use among insured households is still not universal, and understanding of the barriers to use, including supply-side constraints, will help improve universal health coverage.

Health services availability and readiness moderate cash transfer impacts on health insurance enrolment: evidence from the LEAP 1000 cash transfer program in Ghana.

BACKGROUND: Expanding health insurance coverage is a priority under Sustainable Development Goal 3. To address the intersection between poverty and health and remove cost barriers, the government of Ghana established the National Health Insurance Scheme (NHIS). Government further linked NHIS with the Livelihood Empowerment Against Poverty (LEAP) 1000 cash transfer program by waiving premium fees for LEAP 1000 households. This linkage led to increased NHIS enrolment, however, large enrolment gaps remained. One potential reason for failure to enroll may relate to the poor quality of health services. METHODS: We examine whether LEAP 1000 impacts on NHIS enrolment were moderated by health facilities' service availability and readiness. RESULTS: We find that adults in areas with the highest service availability and readiness are 18 percentage points more likely to enroll in NHIS because of LEAP 1000, compared to program effects of only 9 percentage points in low service availability and readiness areas. Similar differences were seen for enrolment among children (20 v. 0 percentage points) and women of reproductive age (25 v. 10 percentage points). CONCLUSIONS: We find compelling evidence that supply-side factors relating to service readiness and availability boost positive impacts of a cash transfer program on NHIS enrolment. Our work suggests that demand-side interventions coupled with supply-side strengthening may facilitate greater population-level benefits down the line. In the quest for expanding financial protection towards accelerating the achievement of universal health coverage, policymakers in Ghana should prioritize the integration of efforts to simultaneously address demand- and supply-side factors.

Effects of Government-Implemented Cash Plus Model on Violence Experiences and Perpetration Among Adolescents in Tanzania, 2018‒2019.

Objectives. To examine the impacts of a government-implemented cash plus program on violence experiences and perpetration among Tanzanian adolescents. Methods. We used data from a cluster randomized controlled trial (n = 130 communities) conducted in the Mbeya and Iringa regions of Tanzania to isolate impacts of the "plus" components of the cash plus intervention. The panel sample comprised 904 adolescents aged 14 to 19 years living in households receiving a government cash transfer. We estimated intent-to-treat impacts on violence experiences, violence perpetration, and pathways of impact. Results. The plus intervention reduced female participants' experiences of sexual violence by 5 percentage points and male participants' perpetration of physical violence by 6 percentage points. There were no intervention impacts on emotional violence, physical violence, or help seeking. Examining pathways, we found positive impacts on self-esteem and participation in livestock tending and, among female participants, a positive impact on sexual debut delays and a negative effect on school attendance. Conclusions. By addressing poverty and multidimensional vulnerability, integrated social protection can reduce violence. Public Health Implications. There is high potential for scale-up and sustainability, and this program reaches some of the most vulnerable and marginalized adolescents.

Geostatistical linkage of national demographic and health survey data: a case study of Tanzania.

BACKGROUND: When Service Provision Assessment (SPA) surveys on primary health service delivery are combined with the nationally representative household survey-Demographic and Health Survey (DHS), they can provide key information on the access, utilization, and equity of health service availability in low- and middle-income countries. However, existing linkage methods have been established only at aggregate levels due to known limitations of the survey datasets. METHODS: For the linkage of two data sets at a disaggregated level, we developed a geostatistical approach where SPA limitations are explicitly accounted for by identifying the sites where health facilities might be present but not included in SPA surveys. Using the knowledge gained from SPA surveys related to the contextual information around facilities and their spatial structure, we made an inference on the service environment of unsampled health facilities. The geostatistical linkage results on the availability of health service were validated using two criteria-prediction accuracy and classification error. We also assessed the effect of displacement of DHS clusters on the linkage results using simulation. RESULTS: The performance evaluation of the geostatistical linkage method, demonstrated using information on the general service readiness of sampled health facilities in Tanzania, showed that the proposed methods exceeded the performance of the existing methods in terms of both prediction accuracy and classification error. We also found that the geostatistical linkage methods are more robust than existing methods with respect to the displacement of DHS clusters. CONCLUSIONS: The proposed geospatial approach minimizes the methodological issues and has potential to be used in various public health research applications where facility and population-based data need to be combined at fine spatial scale.

Linking poverty-targeted social protection and Community Based Health Insurance in Ethiopia: Enrolment, linkages, and gaps.

BACKGROUND: Community-Based Health Insurance (CBHI) has received increasing attention in low and middle-income countries as a pathway toward universal health coverage. In 2011, the government of Ethiopia piloted CBHI and subsequently integrated CBHI with its flagship social protection programme, the Productive Safety Net Program (PSNP) which was established in 2005. We examined enrolment decisions by PSNP households, including, understanding of the programme, reasons for non-coverage, and factors associated with enrolment decisions. METHODS: Cross-sectional data for this study come from an Integrated Safety Net Program (ISNP) baseline survey implemented in four rural woredas in Amhara region, Ethiopia between December 2018 and February 2019. We collected data from 5398 PSNP beneficiary households, categorized as either Public Work (PW) or Permanent Direct Support (PDS) types. We used descriptive methods to characterize sample households and fitted binary logistic regression to identify factors associated with households' CBHI enrolment decisions. RESULTS: Current CBHI enrolment is higher among PW households (70.1 %) than PDS clients (50.3 %). The most common reason for not enrolling in both PW and PDS households is cost. Results further show that the following characteristics are positively associated with CBHI enrolment: the number of children and working-age adults in the household, older household head, female household head, married household head, having been food insecure in the previous 12 months, heads having experienced illness in the past month, and increasing household wealth status. CONCLUSION: While demographic factors are important in households' decisions to enrol in CBHI, various mechanisms could be used to increase enrolment among vulnerable households such as PDS clients. In this regard, while better communication about CBHI could increase enrolment for some households, other poor and vulnerable households will need fee waivers to induce enrolment.

Exploring multilevel social determinants of depressive symptoms for Tanzanian adolescents: evidence from a cross-sectional study.

BACKGROUND: Depression has substantial and enduring impacts for adolescents, particularly those living in poverty. Yet, evidence on its determinants in low-income countries remains scarce. We examined the social determinants of depressive symptoms for Tanzanian adolescents. METHODS: We used cross-sectional data for 2458 adolescents (aged 14-19), to describe associations with depressive symptoms within and across five domains-demographic, economic, neighbourhood, environmental and social-cultural-using linear mixed models. We estimated depressive symptoms using the 10-item Centre for Epidemiological Studies Depression Scale, which ranges from 0 to 30 and increases with additional symptoms. RESULTS: Factors associated with depressive symptoms in the fully adjusted models included experiencing five or more household economic shocks (ß=2.40; 95% CI 1.48 to 3.32), experiencing droughts/floods (ß=0.76; 95% CI 0.36 to 1.17), being in a relationship (ß=1.82; 95% CI 1.30 to 2.33), and having moderate (ß=1.26; 95% CI 0.80 to 1.71) or low (ß=2.27; 95% CI 1.81 to 2.74) social support. Exclusive schooling was protective compared with being engaged in both school and paid work (ß=1.07; 95% CI 0.05 to 2.61) and not engaged in either (ß=0.73; 95% CI 0.24 to 1.22). Household size and relationship status were more important factors for girls, while employment status, and extreme precipitation were more important for boys. CONCLUSION: Mental health is associated with determinants from multiple domains. Results suggest that environmental shocks related to climate change contribute to poor mental health in adolescents, highlighting an important area for intervention and research.

Impacts of a Cash Plus Intervention on Gender Attitudes Among Tanzanian Adolescents.

PURPOSE: Inequitable attitudes toward men's and women's roles, rights, and responsibilities are associated with poor health-related outcomes, particularly for girls and women. Yet, we know relatively little about what interventions work to improve gender-equitable attitudes among adolescents in low-income countries. This study examines the impact of a government-implemented "cash plus" intervention on gender-equitable attitudes among adolescents in Tanzania. The intervention includes discussions and activities related to gender norms, embedded in broader life skills, livelihoods, and health training. METHODS: The study utilizes a cluster randomized design, using data from 1,933 males and females aged 14-19 years at baseline who took part in the baseline (2017), midline (2018), and endline (2019) surveys. Gender attitudes were measured using 24 items from the Gender-Equitable Men (GEM) Scale. We estimate intent-to-treat impacts on the GEM scale and four subscales (violence, sexual relationships, reproductive health, and domestic chores). RESULTS: The "cash plus" intervention had a significant impact on the overall GEM scale at midline. The intervention increased gender-equitable attitudes on the domestic chores subscale at both midline and endline. The intervention improved gender-equitable attitudes among males on the overall GEM scale and three subscales at midline and on two subscales at endline, but it had no impacts among females. CONCLUSIONS: Gender transformative social protection is currently being advocated as a way to address the gendered nature of poverty and its consequences. Initiatives such as the one studied here, which address the multifaceted drivers of gender inequities, could be a promising way forward.

Uptake of HIV testing among adolescents and associated adolescent-friendly services.

BACKGROUND: HIV testing remains low among adolescents. Making public health services more adolescent-friendly is one strategy used to encourage testing. However, it remains unclear whether government-led initiatives have a meaningfully impact. METHODS: The current study is observational and utilizes two sources of data (health-facility and adolescent-level) from one round of data collection of an on-going, longitudinal impact evaluation of a pilot cash plus program targeting adolescents. This study linked data from adolescent surveys (n = 2191) to data collected from nearby government-run health facilities (n = 91) in two rural regions of Tanzania. We used log binomial regression models to estimate the association between specific adolescent-friendly health service (AFHS) characteristics and adolescents' uptake of 1) HIV testing and 2) visiting a health care facility in the past year for sexual and reproductive health (SRH) services. RESULTS: Most adolescents (67%) lived in a village with a health facility, and all offered HIV services. We find, however, that AFHS have not been fully implemented. For example, less than 40% of facilities reported that they had guidelines for adolescent care. Only 12% of facilities had a system in place for referral and follow-up with adolescent clients, yet this was an important predictor of both past-year HIV testing (RR = 1.28, p < 0.1) and SRH visits (RR = 1.44, p < 0.05). Less than half (44%) offered services for survivors of gender-based violence (GBV), a significant predictor of past-year HIV testing (RR = 1.20, p < 0.05) and SRH visits (RR = 1.41, p < 0.01) among sexually-active adolescents. CONCLUSIONS: We find that national guidelines on AFHS have not been fully translated into practice at the local level. We highlight particular gaps in adolescent referral systems and GBV services. Scaling up these two essential services could encourage greater HIV testing among a high-risk population, in addition to providing much needed support for survivors of violence.

Impact evaluation of a social protection programme paired with fee waivers on enrolment in Ghana's National Health Insurance Scheme.

OBJECTIVES: The study aimed to understand the impact of integrating a fee waiver for the National Health Insurance Scheme (NHIS) with Ghana's Livelihood Empowerment Against Poverty (LEAP) 1000 cash transfer programme on health insurance enrolment. SETTING: The study was conducted in five districts implementing Ghana's LEAP 1000 programme in Northern and Upper East Regions. PARTICIPANTS: Women, from LEAP households, who were pregnant or had a child under 1 year and who participated in baseline and 24-month surveys (2497) participated in the study. INTERVENTION: LEAP provides bimonthly cash payments combined with a premium waiver for enrolment in NHIS to extremely poor households with orphans and vulnerable children, elderly with no productive capacity and persons with severe disability. LEAP 1000, the focus of the current evaluation, expanded eligibility in 2015 to those households with a pregnant woman or child under the age of 12 months. Over the course of the study, households received 13 payments. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcomes included current and ever enrolment in NHIS. Secondary outcomes include reasons for not enrolling in NHIS. We conducted a mixed-methods impact evaluation using a quasi-experimental design and estimated intent-to-treat impacts on health insurance enrolment among children and adults. Longitudinal qualitative interviews were conducted with an embedded cohort of 20 women and analysed using systematic thematic coding. RESULTS: Current enrolment increased among the treatment group from 37.4% to 46.6% (n=5523) and decreased among the comparison group from 37.3% to 33.3% (n=4804), resulting in programme impacts of 14 (95% CI 7.8 to 20.5) to 15 (95% CI 10.6 to 18.5) percentage points for current NHIS enrolment. Common reasons for not enrolling were fees and travel. CONCLUSION: While impacts on NHIS enrolment were significant, gaps remain to maximise the potential of integrated programming. NHIS and LEAP could be better streamlined to ensure poor households fully benefit from both services, in a further step towards integrated social protection.

List randomization for soliciting experience of intimate partner violence: Application to the evaluation of Zambia's unconditional child grant program.

Social scientists have increasingly invested in understanding how to improve data quality and measurement of sensitive topics in household surveys. We utilize the technique of list randomization to collect measures of physical intimate partner violence in an experimental impact evaluation of the Government of Zambia's Child Grant Program. The Child Grant Program is an unconditional cash transfer, which targeted female caregivers of children under the age of 5 in rural areas to receive the equivalent of US $24 as a bimonthly stipend. The implementation results show that the list randomization methodology functioned as planned, with approximately 15% of the sample identifying 12-month prevalence of physical intimate partner violence. According to this measure, after 4 years, the program had no measurable effect on partner violence. List randomization is a promising approach to incorporate sensitive measures into multitopic evaluations; however, more research is needed to improve upon methodology for application to measurement of violence.

Women's Individual Asset Ownership and Experience of Intimate Partner Violence: Evidence From 28 International Surveys.

OBJECTIVES: To assess the oft-perceived protective relationship between women's asset ownership and experience of intimate partner violence (IPV) in the previous 12 months. METHODS: We used international survey data from women aged 15 to 49 years from 28 Demographic and Health Surveys (2010-2014) to examine the association between owning assets and experience of recent IPV, matching on household wealth by using multivariate probit models. Matching methods helped to account for the higher probability that women in wealthier households also have a higher likelihood of owning assets. RESULTS: Asset ownership of any type was negatively associated with IPV in 3 countries, positively associated in 5 countries, and had no significant relationship in 20 countries (P < .10). Disaggregation by asset type, sole or joint ownership, women's age, and community level of women's asset ownership similarly showed no conclusive patterns. CONCLUSIONS: Results suggest that the relationship between women's asset ownership and IPV is highly context specific. Additional methodologies and data are needed to identify causality, and to understand how asset ownership differs from other types of women's economic empowerment.

Understanding the linkages between social safety nets and childhood violence: a review of the evidence from low- and middle-income countries.

As many as one billion children experience violence every year, and household- and community-level poverty are among the risk factors for child protection violations. Social safety nets (SSNs) are a main policy tool to address poverty and vulnerability, and there is substantial evidence demonstrating positive effects on children's health and human capital. This paper reviews evidence and develops a framework to understand linkages between non-contributory SSNs and the experience of childhood emotional, physical and sexual violence in low- and middle-income countries. We catalogue 14 rigorous impact evaluations, 11 of which are completed, analysing 57 unique impacts on diverse violence indicators. Among these impacts, approximately one in five represent statistically significant protective effects on childhood violence. Promising evidence relates to sexual violence among female adolescents in Africa, while there is less clear evidence of significant impacts in other parts of the developing world, and on young child measures, including violent discipline. Further, few studies are set up to meaningfully unpack mechanisms between SSNs and childhood violence; however, those most commonly hypothesized operate at the household level (through increases in economic security and reductions in poverty-related stress), the interpersonal level (improved parental behaviours, caregiving practices, improved psychosocial well-being) and at the child-level (protective education and decreases in problem or risky behaviours). It is important to emphasize that traditional SSNs are never designed with violence prevention as primary objectives, and thus should not be considered as standalone interventions to reduce risks for childhood violence. However, SSNs, particularly within integrated protection systems, appear to have potential to reduce violence risk. Linkages between SSNs and childhood violence are understudied, and investments should be made to close this evidence gap.

Poverty and perceived stress: Evidence from two unconditional cash transfer programs in Zambia.

INTRODUCTION: Poverty is a chronic stressor that can lead to poor physical and mental health. This study examines whether two similar government poverty alleviation programs reduced the levels of perceived stress and poverty among poor households in Zambia. METHOD: Secondary data from two cluster randomized controlled trials were used to evaluate the impacts of two unconditional cash transfer programs in Zambia. Participants were interviewed at baseline and followed over 36 months. Perceived stress among female caregivers was assessed using the Cohen Perceived Stress Scale (PSS). Poverty indicators assessed included per capita expenditure, household food security, and (nonproductive) asset ownership. Fixed effects and ordinary least squares regressions were run, controlling for age, education, marital status, household demographics, location, and poverty status at baseline. RESULTS: Cash transfers did not reduce perceived stress but improved economic security (per capita consumption expenditure, food insecurity, and asset ownership). Among these poverty indicators, only food insecurity was associated with perceived stress. Age and education showed no consistent association with stress, whereas death of a household member was associated with higher stress levels. CONCLUSION: In this setting, perceived stress was not reduced by a positive income shock but was correlated with food insecurity and household deaths, suggesting that food security is an important stressor in this context. Although the program did reduce food insecurity, the size of the reduction was not enough to generate a statistically significant change in stress levels. The measure used in this study appears not to be correlated with characteristics to which it has been linked in other settings, and thus, further research is needed to examine whether this widely used perceived stress measure appropriately captures the concept of perceived stress in this population.

How does a national poverty programme influence sexual debut among Kenyan adolescents?

Cash transfer programmes have recently emerged as promising interventions for HIV prevention among adolescents in Africa. However, the pathways through which risk reduction occurs are not well understood. We examine data on 1429 adolescents and youth from the Kenya Cash Transfer for Orphans and Vulnerable Children, which has been shown to result in delayed sexual debut among adolescents. We explored three potential mediating pathways: schooling, socio-economic status and psycho-social status. None of these hypothesised mediators greatly altered the main effect. However, school attendance had a larger protective effect on sexual debut among females but was only increased by the programme among males. This gendered pattern of effects may explain why we did not see a mediating effect of the cash transfer through schooling, despite schooling's protective effects against early sexual debut. Results also suggest that cash transfer programmes in Africa can contribute to the reduction of HIV related risk behaviours.

Equity and achievement in access to contraceptives in East Africa between 2000 and 2010.

OBJECTIVE: To examine trends in equity in contraceptive use, and in contraceptive-prevalence rates in six East African countries. METHODS: In this repeated cross-sectional study, Demographic and Health Surveys Program data from women aged 15-49 years in Ethiopia, Kenya, Malawi, Rwanda, Tanzania, and Uganda between 2000 and 2010 were analyzed. Individuals were ranked according to wealth quintile, stratified urban/rural populations, and calculated concentration index-a statistic integrating information from all wealth quintiles to analyze disparities. RESULTS: Equity and contraceptive-prevalence rates increased in most country regions over the study period. Notably, in rural Rwanda, contraceptive-prevalence rates increased from 3.9 to 44.0, and urban Kenya became the most equitable country region, with a concentration index of 0.02. The Pearson correlation coefficient between improvements in concentration index and contraceptive-prevalence rates was 0.52 (P=0.011). CONCLUSION: The results indicate that countries seeking to increase contraceptive use should prioritize equity in access to services and contraceptives.

Health Assimilation among Hispanic Immigrants in the United States: The Impact of Ignoring Arrival-cohort Effects.

A large literature has documented that Hispanic immigrants have a health advantage over their U.S.-born counterparts upon arrival in the United States. Few studies, however, have disentangled the effects of immigrants' arrival cohort from their tenure of U.S. residence, an omission that could produce imprecise estimates of the degree of health decline experienced by Hispanic immigrants as their U.S. tenure increases. Using data from the 1996-to-2014 waves of the March Current Population Survey, we show that the health (i.e., self-rated health) of Hispanic immigrants varies by both arrival cohort and U.S. tenure for immigrants hailing from most of the primary sending countries/regions of Hispanic immigrants. We also find evidence that acculturation plays an important role in determining the health trajectories of Hispanic immigrants. With respect to self-rated health, however, our findings demonstrate that omitting arrival-cohort measures from health assimilation models may result in overestimates of the degree of downward health assimilation experienced by Hispanic immigrants.

Improving Health-Related Quality of Life among People Living with HIV: Results from an Impact Evaluation of a Food Assistance Program in Uganda.

INTRODUCTION: Widespread food insecurity in Africa continues to compromise an effective response to the AIDS epidemic. Health-related quality of life (HRQoL) is a comprehensive indicator of physical, mental, and social well-being that is associated with food insecurity and increasingly used to assess the well-being of people living with HIV/AIDS (PLHIV). We examined the impact of a food assistance intervention, previously shown to have reduced household food insecurity and improved nutritional status, on HRQoL of PLHIV. METHODS: We capitalized on an existing intervention targeting antiretroviral therapy (ART)- naïve PLHIV in Uganda, and conducted a prospective impact evaluation including a treatment and a comparison group. Data analyzed included 640 participants from two districts (318 in the intervention district) interviewed in both clinic and household settings at baseline and again approximately one year later. The main outcomes considered were physical and mental health dimensions of HRQoL, and other outcomes included self- and healthcare provider-reported symptoms. We utilized difference-in-difference propensity score matching methodologies to infer causality and examine program impacts. RESULTS: Over 12 months, food assistance significantly increased physical health scores (PHS) by 2.85 (P < .01) or approximately 0.35 SD, and reduced substantially the number of self- and healthcare provider-reported HIV-related symptoms by 3.83 and 2.68, respectively (P < .01). There was no significant impact, however, on mental health scores (MHS). CONCLUSIONS: This study demonstrates the potential importance for HRQoL of including food assistance programming as part of the standard of care for PLHIV in areas of widespread food insecurity.
