Housing, sanitation and living conditions affecting SARS-CoV-2 prevention interventions in 54 African countries.

The feasibility of non-pharmacological public health interventions (NPIs) such as physical distancing or isolation at home to prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in low-resource countries is unknown. Household survey data from 54 African countries were used to investigate the feasibility of SARS-CoV-2 NPIs in low-resource settings. Across the 54 countries, approximately 718 million people lived in households with ⩾6 individuals at home (median percentage of at-risk households 56% (95% confidence interval (CI), 51% to 60%)). Approximately 283 million people lived in households where ⩾3 people slept in a single room (median percentage of at-risk households 15% (95% CI, 13% to 19%)). An estimated 890 million Africans lack on-site water (71% (95% CI, 62% to 80%)), while 700 million people lacked in-home soap/washing facilities (56% (95% CI, 42% to 73%)). The median percentage of people without a refrigerator in the home was 79% (95% CI, 67% to 88%), while 45% (95% CI, 39% to 52%) shared toilet facilities with other households. Individuals in low-resource settings have substantial obstacles to implementing NPIs for mitigating SARS-CoV-2 transmission. These populations urgently need to be prioritised for coronavirus disease 2019 vaccination to prevent disease and to contain the global pandemic.

The Impact of Parental and Medical Leave Policies on Socioeconomic and Health Outcomes in OECD Countries: A Systematic Review of the Empirical Literature.

Policy Points: Historically, reforms that have increased the duration of job-protected paid parental leave have improved women's economic outcomes. By targeting the period around childbirth, access to paid parental leave also appears to reduce rates of infant mortality, with breastfeeding representing one potential mechanism. The provision of more generous paid leave entitlements in countries that offer unpaid or short durations of paid leave could help families strike a balance between the competing demands of earning income and attending to personal and family well-being. CONTEXT: Policies legislating paid leave from work for new parents, and to attend to individual and family illness, are common across Organisation for Economic Co-operation and Development (OECD) countries. However, there exists no comprehensive review of their potential impacts on economic, social, and health outcomes. METHODS: We conducted a systematic review of the peer-reviewed literature on paid leave and socioeconomic and health outcomes. We reviewed 5,538 abstracts and selected 85 published papers on the impact of parental leave policies, 22 papers on the impact of medical leave policies, and 2 papers that evaluated both types of policies. We synthesized the main findings through a narrative description; a meta-analysis was precluded by heterogeneity in policy attributes, policy changes, outcomes, and study designs. FINDINGS: We were able to draw several conclusions about the impact of parental leave policies. First, extensions in the duration of paid parental leave to between 6 and 12 months were accompanied by attendant increases in leave-taking and longer durations of leave. Second, there was little evidence that extending the duration of paid leave had negative employment or economic consequences. Third, unpaid leave does not appear to confer the same benefits as paid leave. Fourth, from a population health perspective, increases in paid parental leave were consistently associated with better infant and child health, particularly in terms of lower mortality rates. Fifth, paid paternal leave policies of adequate length and generosity have induced fathers to take additional time off from work following the birth of a child. How medical leave policies for personal or family illness influence health has not been widely studied. CONCLUSIONS: There is substantial quasi-experimental evidence to support expansions in the duration of job-protected paid parental leave as an instrument for supporting women's labor force participation, safeguarding women's incomes and earnings, and improving child survival. This has implications, in particular, for countries that offer shorter durations of job-protected paid leave or lack a national paid leave entitlement altogether.

What explains gender inequalities in HIV/AIDS prevalence in sub-Saharan Africa? Evidence from the demographic and health surveys.

BACKGROUND: Women are disproportionally affected by human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in sub-Saharan Africa (SSA). The determinants of gender inequality in HIV/AIDS may vary across countries and require country-specific interventions to address them. This study aimed to identify the socio-demographic and behavioral characteristics underlying gender inequalities in HIV/AIDS in 21 SSA countries. METHODS: We applied an extension of the Blinder-Oaxaca decomposition approach to data from Demographic and Health Surveys and AIDS Indicator Surveys to quantify the differences in HIV/AIDS prevalence between women and men attributable to socio-demographic factors, sexual behaviours, and awareness of HIV/AIDS. We decomposed gender inequalities into two components: the percentage attributable to different levels of the risk factors between women and men (the "composition effect") and the percentage attributable to risk factors having differential effects on HIV/AIDS prevalence in women and men (the "response effect"). RESULTS: Descriptive analyses showed that the difference between women and men in HIV/AIDS prevalence varied from a low of 0.68 % (P = 0.008) in Liberia to a high of 11.5 % (P < 0.001) in Swaziland. The decomposition analysis showed that 84 % (P < 0.001) and 92 % (P < 0.001) of the higher prevalence of HIV/AIDS among women in Uganda and Ghana, respectively, was explained by the different distributions of HIV/AIDS risk factors, particularly age at first sex between women and men. In the majority of countries, however, observed gender inequalities in HIV/AIDS were chiefly explained by differences in the responses to risk factors; the differential effects of age, marital status and occupation on prevalence of HIV/AIDS for women and men were among the significant contributors to this component. In Cameroon, Guinea, Malawi and Swaziland, a combination of the composition and response effects explained gender inequalities in HIV/AIDS prevalence. CONCLUSIONS: The factors that explain gender inequality in HIV/AIDS in SSA vary by country, suggesting that country-specific interventions are needed. Unmeasured factors also contributed substantially to the difference in HIV/AIDS prevalence between women and men, highlighting the need for further study.

A call to action: training public health students to be effective agents for social change.

In the 21st century, we face enormous public health challenges that differ fundamentally from those of the last century, because these challenges involve widespread societal change and complexity. To address these challenges, public health professionals need to be able to place their work in a larger social context, understand local and global perspectives on a deeper level, and effectively engage a wide variety of stakeholders. To confer these skills, we need to change the way we train our students. We present two examples of low-cost innovative approaches to teaching public health that promote active engagement with individuals across a wide range of backgrounds and fields and that train students to be effective agents for change.

Socioeconomic inequalities in HIV/AIDS prevalence in sub-Saharan African countries: evidence from the Demographic Health Surveys.

INTRODUCTION: Extant studies universally document a positive gradient between socioeconomic status (SES) and health. A notable exception is the apparent concentration of HIV/AIDS among wealthier individuals. This paper uses data from the Demographic Health Surveys and AIDS Indicator Surveys to examine socioeconomic inequalities in HIV/AIDS prevalence in 24 sub-Saharan African (SSA) countries, the region that accounts for two-thirds of the global HIV/AIDS burden. METHODS: The relative and generalized concentration indices (RC and GC) were used to quantify wealth-based socioeconomic inequalities in HIV/AIDS prevalence for the total adult population (aged 15-49), for men and women, and in urban and rural areas in each country. Further, we decomposed the RC and GC indices to identify the determinants of socioeconomic inequalities in HIV/AIDS prevalence in each country. RESULTS: Our findings demonstrated that HIV/AIDS was concentrated among higher SES individuals in the majority of SSA countries. Swaziland and Senegal were the only countries in the region where HIV/AIDS was concentrated among individuals living in poorer households. Stratified analyses by gender showed HIV/AIDS was generally concentrated among wealthier men and women. In some countries, including Kenya, Lesotho Uganda, and Zambia, HIV/AIDS was concentrated among the poor in urban areas but among wealthier adults in rural areas. Decomposition analyses indicated that, besides wealth itself (median = 49%, interquartile range [IQR] = 90%), urban residence (median = 54%, IQR = 81%) was the most important factor contributing to the concentration of HIV/AIDS among wealthier participants in SSA countries. CONCLUSIONS: Further work is needed to understand the mechanisms explaining the concentration of HIV/AIDS among wealthier individuals and urban residents in SSA. Higher prevalence of HIV/AIDS could be indicative of better care and survival among wealthier individuals and urban adults, or reflect greater risk behaviour and incidence. Moreover, differential findings across countries suggest that effective intervention efforts for reducing the burden of HIV/AIDS in the SSA should be country specific.

Paid health and family leave: the Canadian experience in the global context.

OBJECTIVES: Two thirds of Canadian adults participate in the workforce. Their health and that of their families can be markedly affected by the availability of paid sick leave, paid leave to care for family members' health and paid parental leave. METHODS: We gathered data from all Canadian provinces and territories on these essential leave policies and compared Canadian policies with data collected on 186 United Nations (UN) countries. RESULTS: While Canada pays sickness benefits for 15 weeks for serious illnesses, globally at least 90 countries provide benefits for at least 26 weeks or until recovery. Moreover, within Canada only Saskatchewan and Quebec guarantee job protection if sick leave lasts over 12 days. The federal government guarantees Canadian workers six weeks of paid leave to provide care or support to gravely ill family members. Only 39 countries guarantee such leave with pay. Most, but not all, provinces guarantee workers' job protection during compassionate care leave. Eligibility for job protection during parental leave varies across the country from having no restrictions to requiring at least one year of service. CONCLUSION: Compared with Canada, many countries offer a longer duration of paid sick leave for employees and replace a higher percentage of wages lost. Internationally, Canada performs well in having policies that guarantee paid leave to care for dependants with serious illnesses, but it lags behind in the provision of paid leave to address the health needs of children or family members' with non-life-threatening conditions. Finally, while paid parental leave is of adequate duration, the wage replacement rate lowers its accessibility to families with limited means.

The extent of community and public support available to families caring for orphans in Malawi.

There are an estimated 15 million AIDS orphans worldwide. Families play an important role in safeguarding orphans, but they may be increasingly compromised by the HIV/AIDS epidemic. The international aid community has recognized the need to help families continue caring for orphaned children by strengthening their safety nets. Before we build new structures, however, we need to know the extent to which community and public safety nets already provide support to families with orphans. To address this gap, we analyzed nationally representative data from 27,495 children in the 2004-2005 Malawi Integrated Household Survey. We found that communities commonly assisted orphan households through private transfers; organized responses to the orphan crisis were far less frequent. Friends and relatives provided assistance to over 75% of orphan households through private gifts, but the value of such support was relatively low. Over 40% of orphans lived in a community with support groups for the chronically ill and approximately a third of these communities provided services specifically for orphans and other vulnerable children. Public programs, which form a final safety net for vulnerable households, were more widespread. Free/subsidized agricultural inputs and food were the most commonly used public safety nets by children's households in the past year (44 and 13%, respectively), and households with orphans were more likely to be beneficiaries. Malawi is poised to drastically expand safety nets to orphans and their families, and these findings provide an important foundation for this process.

Moving from preventing HIV/AIDS in its infancy to preventing family illness and death (PFID).

In April 2007, UNAIDS released Securing the future--advocating for children, a call for the global community to recognize that "children still remain largely absent from national and international political responses to the AIDS pandemic". Most efforts to date to protect children from HIV have focused on prevention of mother-to-child transmission (PMTCT) programs. Though expanding PMTCT programs, particularly in sub-Saharan Africa, are crucial, even widespread PMTCT programs would still be grossly inadequate for achieving the goal of protecting children from HIV/AIDS. The global community needs to fundamentally reframe its approach to HIV prevention to fully address the health of families, otherwise the future for at-risk children is likely to remain bleak. After identifying challenges with current approaches, we review recent research that provides insights into ways prevention programs may be adapted to better protect families and children from the devastating consequences of HIV/AIDS. Only by protecting families from HIV/AIDS will we be able to achieve the goal of an AIDS-free generation.

Maternal single-dose nevirapine versus placebo as part of an antiretroviral strategy to prevent mother-to-child HIV transmission in Botswana.

BACKGROUND: Single-dose nevirapine given to women and infants reduces mother-to-child HIV transmission, but nevirapine resistance develops in a large percentage of women. OBJECTIVE: To determine whether the maternal nevirapine dose could be eliminated in the setting of zidovudine prophylaxis. DESIGN, SETTING, AND PARTICIPANTS: A 2 x 2 factorial, randomized, clinical trial, with a double-blinded peripartum factor designed to assess the equivalence of maternal single-dose nevirapine versus placebo with respect to HIV transmission. A total of 709 HIV-infected pregnant women were randomized from four district hospitals in Botswana, resulting in 694 live first-born infants. HAART was available for women with AIDS. INTERVENTION: All women received a background of zidovudine from 34 weeks' gestation through delivery, and all infants received single-dose nevirapine at birth and zidovudine from birth through 1 month. Women were randomized to receive either single-dose nevirapine or placebo during labor. MAIN OUTCOME MEASURES: The primary endpoint was infant HIV infection by the 1-month visit. RESULTS: Of the 694 infants in this equivalence study, 15 (4.3%) of 345 in the maternal nevirapine arm were HIV infected by 1 month, versus 13 (3.7%) of 349 in the maternal placebo arm (95% confidence interval for difference, -2.4% to 3.8%), meeting pre-determined equivalence criteria. Nevirapine resistance at 1 month postpartum was detected in 45% of a random sample of women who received nevirapine. CONCLUSIONS: In the setting of maternal zidovudine and infant zidovudine plus single-dose nevirapine, infant HIV infection rates were similar whether women received single-dose nevirapine or placebo. This strategy avoids the potential for maternal nevirapine resistance.

Orphan care in Botswana's working households: growing responsibilities in the absence of adequate support.

OBJECTIVES: Botswana has one of the world's highest HIV-prevalence rates and the world's highest percentages of orphaned children among its population. We assessed the ability of income-earning households in Botswana to adequately care for orphans. METHODS: We used data from the Botswana Family Health Needs Study (2002), a sample of 1033 working adults with caregiving responsibilities who used public services, to assess whether households with orphan-care responsibilities encountered financial and other difficulties. Thirty-seven percent of respondents provided orphan care, usually to extended family members. We applied logistic regression models to determine the factors associated with experiencing problems related to orphan caregiving. RESULTS: Nearly half of working households with orphan-care responsibilities reported experiencing financial and other difficulties because of orphan care. Issues of concern included caring for multiple orphans, caring for sick adults and orphans simultaneously, receiving no assistance, and low income. CONCLUSIONS: The orphan crisis is impoverishing even working households, where caregivers lack sufficient resources to provide basic needs. Neither the public sector nor communities provide adequate safety nets. International assistance is critical to build capacity within the social welfare infrastructure and to fund community-level activities that support households. Lessons from Botswana's orphan crisis can provide valuable insights to policymakers throughout sub-Saharan Africa.

Breastfeeding plus infant zidovudine prophylaxis for 6 months vs formula feeding plus infant zidovudine for 1 month to reduce mother-to-child HIV transmission in Botswana: a randomized trial: the Mashi Study.

CONTEXT: Postnatal transmission of human immunodeficiency virus-1 (HIV) via breastfeeding reverses gains achieved by perinatal antiretroviral interventions. OBJECTIVE: To compare the efficacy and safety of 2 infant feeding strategies for the prevention of postnatal mother-to-child HIV transmission. DESIGN, SETTING, AND PATIENTS: A 2 x 2 factorial randomized clinical trial with peripartum (single-dose nevirapine vs placebo) and postpartum infant feeding (formula vs breastfeeding with infant zidovudine prophylaxis) interventions. In Botswana between March 27, 2001, and October 29, 2003, 1200 HIV-positive pregnant women were randomized from 4 district hospitals. Infants were evaluated at birth, monthly until age 7 months, at age 9 months, then every third month through age 18 months. INTERVENTION: All of the mothers received zidovudine 300 mg orally twice daily from 34 weeks' gestation and during labor. Mothers and infants were randomized to receive single-dose nevirapine or placebo. Infants were randomized to 6 months of breastfeeding plus prophylactic infant zidovudine (breastfed plus zidovudine), or formula feeding plus 1 month of infant zidovudine (formula fed). MAIN OUTCOME MEASURES: Primary efficacy (HIV infection by age 7 months and HIV-free survival by age 18 months) and safety (occurrence of infant adverse events by 7 months of age) end points were evaluated in 1179 infants. RESULTS: The 7-month HIV infection rates were 5.6% (32 infants in the formula-fed group) vs 9.0% (51 infants in the breastfed plus zidovudine group) (P = .04; 95% confidence interval for difference, -6.4% to -0.4%). Cumulative mortality or HIV infection rates at 18 months were 80 infants (13.9%, formula fed) vs 86 infants (15.1% breastfed plus zidovudine) (P = .60; 95% confidence interval for difference, -5.3% to 2.9%). Cumulative infant mortality at 7 months was significantly higher for the formula-fed group than for the breastfed plus zidovudine group (9.3% vs 4.9%; P = .003), but this difference diminished beyond month 7 such that the time-to-mortality distributions through age 18 months were not significantly different (P = .21). CONCLUSIONS: Breastfeeding with zidovudine prophylaxis was not as effective as formula feeding in preventing postnatal HIV transmission, but was associated with a lower mortality rate at 7 months. Both strategies had comparable HIV-free survival at 18 months. These results demonstrate the risk of formula feeding to infants in sub-Saharan Africa, and the need for studies of alternative strategies.

Exploring the drivers of health and healthcare access in Zambian prisons: a health systems approach.

BACKGROUND: Prison populations in sub-Saharan Africa (SSA) experience a high burden of disease and poor access to health care. Although it is generally understood that environmental conditions are dire and contribute to disease spread, evidence of how environmental conditions interact with facility-level social and institutional factors is lacking. This study aimed to unpack the nature of interactions and their influence on health and healthcare access in the Zambian prison setting. METHODS: We conducted in-depth interviews of a clustered random sample of 79 male prisoners across four prisons, as well as 32 prison officers, policy makers and health care workers. Largely inductive thematic analysis was guided by the concepts of dynamic interaction and emergent behaviour, drawn from the theory of complex adaptive systems. RESULTS: A majority of inmates, as well as facility-based officers reported anxiety linked to overcrowding, sanitation, infectious disease transmission, nutrition and coercion. Due in part to differential wealth of inmates and their support networks on entering prison, and in part to the accumulation of authority and material wealth within prison, we found enormous inequity in the standard of living among prisoners at each site. In the context of such inequities, failure of the Zambian prison system to provide basic necessities (including adequate and appropriate forms of nutrition, or access to quality health care) contributed to high rates of inmate-led and officer-led coercion with direct implications for health and access to healthcare. CONCLUSIONS: This systems-oriented analysis provides a more comprehensive picture of the way resource shortages and human interactions within Zambian prisons interact and affect inmate and officer health. While not a panacea, our findings highlight some strategic entry-points for important upstream and downstream reforms including urgent improvement in the availability of human resources for health; strengthening of facility-based health services systems and more comprehensive pre-service health education for prison officers.

Long time due: reducing tuberculosis mortality in the 21st century.

The beginning and the end of the 20th century were marked by great pandemics: influenza and AIDS. Medical journals do not describe any major tuberculosis (TB) pandemics in the 20th century. Yet TB likely was responsible for more deaths in the last 100 years than influenza and HIV combined. Steadily, insidiously, millions of people die from TB every year. Even under optimal TB control conditions, it is estimated that more than 50 million people will die from TB between 1998 and 2020. Under current TB control conditions, the number is closer to 70 million. It is long past time that the global community committed to a serious program to eliminate tuberculosis mortality. Such a program would require making treatment universally available, making prevention accessible to those in poor countries as well as affluent, addressing the interaction between HIV and TB, and setting serious verifiable goals. A global 5 x 7 initiative that calls for treating an additional 5 million active TB cases per year, and for screening up to five contacts of every TB case, by 2007 would offer an important beginning. With the sustained effort that comes from public commitment, TB can be changed from one of the most important causes of preventable death worldwide to a historical cause of death. Without this effort, TB will remain the silent, steady killer it has been for centuries. The rationale for action, potential and need for success are detailed in this article.

Facilitating working mothers' ability to breastfeed: global trends in guaranteeing breastfeeding breaks at work, 1995-2014.

BACKGROUND: Mothers who work away from home tend to stop breastfeeding earlier than their nonworking counterparts due to workplace barriers. Barriers to breastfeeding discriminate against women and may lead to inequities in children's health outcomes. Guaranteeing paid breastfeeding breaks at work is 1 mechanism that can improve mothers' opportunity to breastfeed in the workplace. OBJECTIVE: This study aimed to assess the trends in the share of countries guaranteeing breastfeeding breaks in the workplace and paid maternal leave that lasts until the infant is 6 months old (the World Health Organization recommended duration for exclusive breastfeeding), between 1995 and 2014. METHODS: Legislation and secondary source data were collected and reviewed for 193 United Nations member states. Legislation was analyzed for content on breastfeeding breaks and maternal leave guarantees. RESULTS: Fifty-one countries (26.7%) in 2014 did not guarantee breastfeeding breaks in any form and 4 countries provided only unpaid breaks or breaks that did not cover the first 6 months of life; since 1995, around 15 countries (10.2%) legislated for such a policy. In 2014, out of 55 countries that did not guarantee paid breastfeeding breaks for the first 6 months after birth, 7 countries guaranteed paid maternal leave for the same duration; 48 countries (25.1%) provided neither paid maternal leave nor paid breastfeeding breaks. CONCLUSION: Progress in the number of countries guaranteeing breastfeeding breaks at work is modest. Adopting measures to facilitate breastfeeding at work can be a critical opportunity for countries to increase breastfeeding rates among the growing number of women in the labor force.

To control and beyond: moving towards eliminating the global tuberculosis threat.

For 10 years the World Health Organisation has had a single answer to the deadly threat of tuberculosis (TB)-provide treatment to smear positive patients and watch them take it. In contrast with confident statements about how global TB would be brought under control when directly observed therapy, short course (DOTS) was introduced, TB continues to rise worldwide. The introduction of selected multiple drug resistant TB treatment programmes, "DOTS-Plus", although important, also focuses on therapy for active TB. HIV endemic countries in particular have experienced tremendous increases in TB despite having DOTS programmes. A critical review of recent epidemiological data and computer models shows that the present international strategy of concentrating on providing treatment for smear positive TB, DOTS and DOTS-Plus, is likely to have only a modest impact on population based TB control. Effective global TB control will require strategies that go beyond relying on treatment of people with active disease.

Low adherence to recommended infant feeding strategies among HIV-infected women: results from the pilot phase of a randomized trial to prevent mother-to-child transmission in Botswana.

Little is known about the ability of women to adhere to recommended feeding strategies to prevent mother-to-child HIV transmission (MTCT) from breast milk. We conducted a pilot study in rural Botswana to prevent MTCT from breast milk. Women were randomized to formula feed their infants or to exclusively breastfeed while providing prophylactic zidovudine. Women who chose to formula feed independently were also followed. Among those with > or = 3 postpartum visits, none of 31 women assigned to breastfeed did so exclusively for 5 months. Seven (22%) of 32 women in the formula arm definitely or probably breastfed by self-report or as witnessed in maternity, and evidence of breast milk on physical examination was present in 50% of women in > or = 2 visits beyond 1 month. Three (18%) of 17 women choosing formula definitely or probably breastfed, and breast milk was present on exam in 53%. We conclude that adherence to 5 months of exclusive breastfeeding did not occur, and that adherence to exclusive formula feeding was sub-optimal and potentially over reported. Breast examination may be a useful adjunct to self-report, but needs to be validated and standardized. Low adherence to infant feeding strategies that differ from local norms will reduce their effectiveness in preventing MTCT.

Self-reported risks for multiple-drug resistance among new tuberculosis cases: implications for drug susceptibility screening and treatment.

BACKGROUND: Multiple drug-resistance in new tuberculosis (TB) cases accounts for the majority of all multiple drug-resistant TB (MDR-TB) worldwide. Effective control requires determining which new TB patients should be tested for MDR disease, yet the effectiveness of global screening recommendations of high-risk groups is unknown. METHODS: Sixty MDR-TB cases with no history of previous TB treatment, 80 drug-sensitive TB and 80 community-based controls were recruited in Lima, Peru between August and December, 2008 to investigate whether recommended screening practices identify individuals presenting with MDR-TB. Odd ratios (OR) and 95% confidence intervals (CI) were calculated using logistic regression to study the association of potential risk factors with case/control variables. RESULTS: MDR-TB cases did not differ from drug-sensitive TB and community controls in rates of human immunodeficiency virus infection, reported hospital or prison visits in the 3 years prior to diagnosis. MDR-TB cases were more likely than drug-sensitive TB controls to have had a recent MDR-TB household contact (OR 4.66, (95% CI 1.56-13.87)); however, only 15 cases (28.3%) reported this exposure. In multivariate modeling, recent TB household contact, but not contact with an MDR-TB case, remained predictive of MDR-TB, OR 7.47, (95% CI 1.91-29.3). Living with a partner rather than parents was associated with a lower risk of MDR-TB, OR 0.15, (95% CI 0.04-0.51). CONCLUSION: Targeted drug susceptibility testing (DST) linked to reported MDR-TB contact or other high-risk exposures does not identify the majority of new TB cases with MDR disease in Lima where it is endemic. All new TB cases should be screened with DST to identify MDR patients. These findings are likely applicable to other regions with endemic MDR-TB.

What causes job loss among former welfare recipients: the role of family health problems.

OBJECTIVE: to test whether women's or children's health status influences the likelihood that low-income single mothers experience job loss. METHODS: Using a nationally representative probability sample from the National Longitudinal Survey of Youth, we estimated whether having a health limitation or having a child with a health limitation was associated with job loss for a sample of 783 women who had previously been on welfare. RESULTS: Both having a health limitation (odds ratio [OR]=1.53; 95% confidence interval [CI], 1.19-1.97) and having a child with a health limitation (OR=1.36; 95% CI, 1.18-1.56) were associated with significantly increased risk of job loss among women previously on welfare. The effects remained significant after adjustment for age, education, marital status, race, age and number of children, and economic conditions. CONCLUSIONS: Dramatic changes in welfare policy in the United States have made many single mothers living in poverty dependent on work as their sole source of income. Although studies have shown that families on welfare are more likely to have health limitations, little is known about how family health affects the ability of poor single mothers to remain employed. These results demonstrate that women with health limitations and mothers of children with health limitations are at particularly high risk of losing their jobs. Public and private policies that can help reduce job loss as a consequence of family health problems are discussed.
