Estimating the costs for implementing a maternity leave cash transfer program for women employed in the informal sector in Brazil and Ghana.

BACKGROUND: Maternity leave policies are designed to protect gender equality and the health of mothers in the workforce and their children. However, maternity leave schemes are often linked to jobs in the formal sector economy. In low- and middle-income countries a large share of women work in the informal sector, and are not eligible to such benefit. This is worrisome from a social justice and a policy perspective and suggests the need for intervening. Costing the implementation of potential interventions is needed for facilitating informed decisions by policy makers. METHODS: We developed and applied a costing methodology to assess the cost of a maternity leave cash transfer to be operated in the informal sector of the economy in Brazil and Ghana, two countries with very different employment structures and socioeconomic contexts. We conducted sensitivity analysis by modeling different numbers of weeks covered. RESULTS: In Brazil, the cost of the maternity cash transfer would be between 0.004% and 0.02% of the GDP, while in Ghana it would range between 0.076% and 0.28% of the GDP. The relative cost of rolling out a maternity intervention in Brazil is between 2.2 to 3.2 times the cost in Ghana depending on the benchmark used to assess the welfare measure. The differences in costs between countries was related to differences in labor market structure as well as demographic characteristics. CONCLUSIONS: Findings show how a standard methodology that relies on routinely available information is feasible and could assist policymakers in estimating the costs of supporting a maternity cash transfer for women employed in the informal sector, such intervention is expected to contribute to social justice, gender equity, and health trajectories.

Time and gender measurement invariance in the modified Calderon depression scale.

BACKGROUND: Assessing change and comparing groups requires high quality and invariant scales. However, there is limited evidence of simultaneous longitudinal and gender measurement invariance for depression scales. This evidence is even more scant with long-established panel studies from low and middle-income countries. METHODS: In this paper, we used three waves (years 2002, 2005, and 2009) of a nationally representative panel study to examine the psychometric properties of the modified Calderon Depression Scale (CAL-DM)-a one-item exclusion of a depression scale designed for a population residing in a middle-income country (i.e., Mexico). Our analytical sample included 16,868 participants: 7,696 men and 9,172 women. Using Confirmatory Factor Analysis (CFA), we first examined overall fit in each wave, and then we tested time, gender, and time-gender measurement invariance across three waves. We also estimated and compared depression score means by gender and time. Finally, we examined the association between depression scores and self-rated health. RESULTS: Our analyses indicated the CAL-DM is a robust scale, suitable for time, gender, and time by gender comparisons. Mean comparisons exemplified how the scale can be used as a latent variable or a summative score. Women have higher depression scores than men and the gap is narrowing from 3.4 in 2002 to 2.5 in 2009. CONCLUSIONS: The CAL-DM is a reliable instrument to measure depression in the Mexican general population that can be used for epidemiological research. Our results will contribute to a burgeoning line of research that examines the social determinants of depression, and the risk factors associated with different individuals' depression trajectories over the life course.

Urban poverty and nutrition challenges associated with accessibility to a healthy diet: a global systematic literature review.

BACKGROUND: There is an increasing global trend towards urbanization. In general, there are less food access issues in urban than rural areas, but this "urban advantage" does not benefit the poorest who face disproportionate barriers to accessing healthy food and have an increased risk of malnutrition. OBJECTIVES: This systematic literature review aimed to assess urban poverty as a determinant of access to a healthy diet, and to examine the contribution of urban poverty to the nutritional status of individuals. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) methodology, our review included quantitative and qualitative studies published in English or in Spanish between 2000 and 2019. The articles were eligible if they focused on nutrition access (i.e. access to a healthy diet) or nutrition outcomes (i.e., anemia, overweight and obesity, micronutrient deficiency, micronutrient malnutrition) among urban poor populations. Articles were excluded if they did not meet pre-established criteria. The quality of the quantitative studies was assessed by applying Khan et al.'s methodology. Similarly, we assessed the quality of qualitative articles through an adapted version of the National Institute for Health and Care Excellence (NICE) methodology checklist. Finally, we systematically analyzed all papers that met the inclusion criteria based on a qualitative content and thematic analysis. RESULTS: Of the 68 papers included in the systematic review, 55 used quantitative and 13 used qualitative methods. Through the analysis of the literature we found four key themes: (i) elements that affect access to healthy eating in individuals in urban poverty, (ii) food insecurity and urban poverty, (iii) risk factors for the nutritional status of urban poor and (iv) coping strategies to limited access to food. Based on the systematization of the literature on these themes, we then proposed a conceptual framework of urban poverty and nutrition. CONCLUSIONS: This systematic review identified distinct barriers posed by urban poverty in accessing healthy diets and its association with poorer nutrition outcomes, hence, questioning the "urban advantage". A conceptual framework emerging from the existing literature is proposed to guide future studies and policies. SYSTEMATIC REVIEW REGISTRATION: PROSPERO Registration number: CRD42018089788 .

Food insecurity measurement and prevalence estimates during the COVID-19 pandemic in a repeated cross-sectional survey in Mexico.

OBJECTIVE: To validate the telephone modality of the Latin American and Caribbean Food Security Scale (ELCSA) included in three waves of a phone survey to estimate the monthly household food insecurity prevalence during the COVID-19 pandemic in Mexico. DESIGN: We examined the reliability and internal validity of the ELCSA scale in three repeated waves of cross-sectional surveys with Rasch models. We estimated the monthly prevalence of food insecurity in the general population and in households with and without children and compared them with a national 2018 survey. We tested concurrent validity by testing associations of food insecurity with socio-economic status and anxiety. SETTING: ENCOVID-19 is a monthly telephone cross-sectional survey collecting information on the well-being of Mexican households during the pandemic lockdown. Surveys used probabilistic samples, and we used data from April (n 833), May (n 850) and June 2020 (n 1674). PARTICIPANTS: Mexicans 18 years or older who had a mobile telephone. RESULTS: ELCSA had an adequate model fit and food insecurity was associated, within each wave, with more poverty and anxiety. The COVID-19 lockdown was associated with an important reduction in food security, decreasing stepwise from 38·9 % in 2018 to 24·9 % in June 2020 in households with children. CONCLUSIONS: Telephone surveys were a feasible strategy to monitor reductions in food security during the COVID-19 lockdown.

Costs of maternity leave to support breastfeeding; Brazil, Ghana and Mexico.

OBJECTIVE: To develop a method to assess the cost of extending the duration of maternity leave for formally-employed women at the national level and apply it in Brazil, Ghana and Mexico. METHODS: We adapted a World Bank costing method into a five-step method to estimate the costs of extending the length of maternity leave mandates. Our method used the unit cost of maternity leave based on working women's weekly wages; the number of additional weeks of maternity leave to be analysed for a given year; and the weighted population of women of reproductive and legal working age in a given country in that year. We weighted the population by the probability of having a baby that year among women in formal employment, according to individual characteristics. We applied nationally representative cross-sectional data from fertility, employment and population surveys to estimate the costs of maternity leave for mothers employed in the formal sector in Brazil, Ghana and Mexico for periods from 12 weeks up to 26 weeks, the WHO target for exclusive breastfeeding. FINDINGS: We estimated that 640 742 women in Brazil, 33 869 in Ghana and 288 655 in Mexico would require formal maternity leave annually. The median weekly cost of extending maternity leave for formally working women was purchasing power parity international dollars (PPP$) 195.07 per woman in Brazil, PPP$ 109.68 in Ghana and PPP$ 168.83 in Mexico. CONCLUSION: Our costing method could facilitate evidence-based policy decisions across countries to improve maternity protection benefits and support breastfeeding.

Costing of actions to safeguard vulnerable Mexican households with young children from the consequences of COVID-19 social distancing measures.

COVID-19 has imposed unprecedented challenges to society. As the pandemic evolves, the social distancing measures that have been globally enforced, while essential, are having undesirable socioeconomic side effects particularly among vulnerable populations. In Mexico, families who depend upon informal employment face increased threats to their wellbeing, and households who in addition have young children may face long-term consequences. The Mexican government has not yet taken actions, but a coalition of non-governmental organizations is advocating in partnership with academic institutions for social protection actions such as a cash transfer and basic services subsidies for families with young children, subsisting from the informal sector economy. To facilitate governmental action, we estimated the costs for implementation of these recommendations. The methodology used could be replicated in other countries facing similar challenges.

How do context variables affect food insecurity in Mexico? Implications for policy and governance.

OBJECTIVE: To assess, from a systems perspective, how climate vulnerability and socio-economic and political differences at the municipal and state levels explain food insecurity in Mexico. DESIGN: Using a cross-sectional design with official secondary data, we estimated three-level multinomial hierarchical linear models. SETTING: The study setting is Mexico's states and municipalities in 2014. PARTICIPANTS: Heads of households in a representative sample of the general population. RESULTS: At the municipal level, vulnerability to climate disasters and a poverty index were significant predictors of food insecurity after adjusting for household-level variables. At the state level, gross domestic product and the number of nutrition programmes helped explain different levels of food insecurity but change in political party did not. Predictors varied in strength and significance according to the level of food insecurity. CONCLUSIONS: Findings evidence that, beyond food assistance programmes and household characteristics, multiple variables operating at different levels - like climate vulnerability and poverty - contribute to explain the degree of food insecurity. Food security governance is a well-suited multisectoral approach to address the complex challenge of hunger and access to a nutritious diet.

Return Migration to Mexico: Does Health Matter?

We use data from three rounds of the Mexican Family Life Survey to examine whether migrants in the United States returning to Mexico in the period 2005-2012 have worse health than those remaining in the United States. Despite extensive interest by demographers in health-related selection, this has been a neglected area of study in the literature on U.S.-Mexico migration, and the few results to date have been contradictory and inconclusive. Using five self-reported health variables collected while migrants resided in the United States and subsequent migration history, we find direct evidence of higher probabilities of return migration for Mexican migrants in poor health as well as lower probabilities of return for migrants with improving health. These findings are robust to the inclusion of potential confounders reflecting the migrants' demographic characteristics, economic situation, family ties, and origin and destination characteristics. We anticipate that in the coming decade, health may become an even more salient issue in migrants' decisions about returning to Mexico, given the recent expansion in access to health insurance in Mexico.

Links between socio-economic circumstances and changes in smoking behavior in the Mexican population: 2002-2010.

While deleterious consequences of smoking on health have been widely publicized, in many developing countries, smoking prevalence is high and increasing. Little is known about the dynamics underlying changes in smoking behavior. This paper examines socio-economic and demographic characteristics associated with smoking initiation and quitting in Mexico between 2002 and 2010. In addition to the influences of age, gender, education, household economic resources and location of residence, changes in marital status, living arrangements and health status are examined. Drawing data from the Mexican Family Life Survey, a rich population-based longitudinal study of individuals, smoking behavior of individuals in 2002 is compared with their behavior in 2010. Logistic models are used to examine socio-demographic and health factors that are associated with initiating and quitting smoking. There are three main findings. First, part of the relationship between education and smoking reflects the role of economic resources. Second, associations of smoking with education and economic resources differ for females and males. Third, there is considerable heterogeneity in the factors linked to smoking behavior in Mexico indicating that the smoking epidemic may be at different stages in different population subgroups. Mexico has recently implemented fiscal policies and public health campaigns aimed at reducing smoking prevalence and discouraging smoking initiation. These programs are likely to be more effective if they target particular socio-economic and demographic sub-groups.

Using Household Expenditure Surveys for Comparable and Replicable Nutritional Analysis: Evidence from México.

In this study, we explore how to use household expenditures and income surveys (HEIS) to provide replicable and comparable measures of nutrients availability at the population level. Our method formalizes the common practice in the literature and consists of three steps: identification of relevant food categories, pairing of food contents food groups in HEIS data, and calculation of the typical amount of nutrients by food group. We illustrate the usage of the method with Mexican data and provide a publicly available data set to readily convert food purchases into six nutrients: calories, proteins, vitamins A and C, iron, and zinc. We perform a descriptive analysis of the evolution of nutrients intake among Mexican households between 2008 and 2020, considering differences by income level. Our results reflect the effect of the COVID-19 pandemic on nutrient availability in Mexican households, mainly driven by a substantial reduction in the expenditure in food consumed away from home, although for most nutrients the trend was stable over most of the period.

How much does it cost to implement the Baby-Friendly Hospital Initiative training step in the United States and Mexico?

The Baby-Friendly Hospital Initiative (BFHI) has been shown to increase breastfeeding rates, improving maternal and child health and driving down healthcare costs via the benefits of breastfeeding. Despite its clear public health and economic benefits, one key challenge of implementing the BFHI is procuring funding to sustain the program. To address this need and help healthcare stakeholders advocate for funds, we developed a structured method to estimate the first-year cost of implementing BFHI staff training, using the United States (US) and Mexico as case studies. The method used a hospital system-wide costing approach, rather than costing an individual hospital, to estimate the average per birth BFHI staff training costs in US and Mexican hospitals with greater than 500 annual births. It was designed to utilize publicly available data. Therefore, we used the 2014 American Hospital Association dataset (n = 1401 hospitals) and the 2018 Mexican Social Security Institute dataset (n = 154 hospitals). Based on our review of the literature, we identified three key training costs and modelled scenarios via an econometric approach to assess the sensitivity of the estimates based on hospital size, level of obstetric care, and training duration and intensity. Our results indicated that BFHI staff training costs ranged from USD 7.27-125.39 per birth in the US and from PPP 2.68-6.14 per birth in Mexico, depending on hospital size and technological capacity. Estimates differed between countries because the US had more hospital staff per birth and higher staff salaries than Mexico. Future studies should examine whether similar, publicly available data exists in other countries to test if our method can be replicated or adapted for use in additional settings. Healthcare stakeholders can better advocate for the funding to implement the entire BFHI program if they are able to generate informed cost estimates for training as we did here.

Migration as a determinant of childhood obesity in the United States and Latin America.

International migration has economic and health implications. The acculturation process to the host country may be linked to childhood obesity. We use the Community Energy Balance (CEB) framework to analyze the relationship between migration and childhood obesity in Mexican households with international migrants. Using longitudinal data from the Mexican Family Life Survey (MxFLS), we examine how migrant networks affect childhood obesity in origin communities. We also review binational health programs that could be effective at tackling childhood obesity in migrant households from Mexico. Children embedded in migrant networks are at greater risk of developing overweight or obesity, suggesting a significant relationship between childhood obesity and international migration in Mexican households. Based on our search criteria, our analysis of health outreach programs shows that Ventanillas de Salud (VDS)/Health Windows has great promise to prevent childhood obesity in a culturally sensitive and trustful environment. The CEB framework is useful to understand how migration contributes to the risk of childhood overweight and obesity in migrant households. VDS is a feasible and replicable strategy with great potential to address childhood obesity among migrant families accounting for the dynamic and binational determinants of childhood obesity.

A longitudinal study of height gaps among Mexican children: Disparities and social inequity.

RATIONALE: Health outcomes such as height are important determinants of social inequities. OBJECTIVE: We assess height gaps in Mexico among boys and girls from distinct subpopulation groups over time. METHOD: We use longitudinal data from the first three waves of the Mexican Family Life Survey (MxFLS) to analyze children's height differentials by gender and by indigenous and poverty status over 7-10 years. We control for children's characteristics, household factors, and mother's height and use the Blinder-Oaxaca Decomposition method to explain disparities in children's height across the three waves of the MxFLS. RESULTS: The main findings suggest that height inequalities among indigenous and extremely poor boys and girls, compared with their non-indigenous and less socioeconomically disadvantaged counterparts, are persistent. The results also reveal that height disparities among girls are consistently greater than those among boys in similar population groups and that height gaps increase over time for girls. CONCLUSIONS: These findings indicate the relevance of social and economic determinants on children's growth potential and the need to examine the association of social determinants on health outcomes. They also underscore the necessity to design and implement public policies that consider a gender perspective.

A systematic review of costing studies for implementing and scaling-up breastfeeding interventions: what do we know and what are the gaps?

Despite the well-established evidence that breastfeeding improves maternal and child health outcomes, global rates of exclusive breastfeeding remain low. Cost estimates can inform stakeholders about the financial resources needed to scale up interventions to ultimately improve breastfeeding outcomes in low-, middle- and high-income countries. To inform the development of comprehensive costing frameworks, this systematic review aimed to (1) identify costing studies for implementing or scaling-up breastfeeding interventions, (2) assess the quality of identified costing studies and (3) examine the availability of cost data to identify gaps that need to be addressed through future research. Peer-reviewed and grey literature were systematically searched using a combination of index terms and relevant text words related to cost and the following breastfeeding interventions: breastfeeding counselling, maternity leave, the World Health Organization International Code of Marketing of Breastmilk Substitutes, the Baby-Friendly Hospital Initiative, media promotion, workplace support and pro-breastfeeding social policies. Data were extracted after having established inter-rater reliability among the first two authors. The quality of studies was assessed using an eight-item checklist for key costing study attributes. Forty-five studies met the inclusion criteria, with the majority including costs for breastfeeding counselling and paid maternity leave. Most cost analyses included key costing study attributes; however, major weaknesses among the studies were the lack of clarity on costing perspectives and not accounting for the uncertainty of reported cost estimates. Costing methodologies varied substantially, standardized costing frameworks are needed for reliably estimating the costs of implementing and scaling-up breastfeeding interventions at local-, national- or global-levels.

Costing a Maternity Leave Cash Transfer to Support Breastfeeding Among Informally Employed Mexican Women.

BACKGROUND: Investing in maternity protection for working women is an important social equity mechanism. Addressing the maternity leave needs of women employed in the informal sector economy should be a priority as more than half of women in Latin America, South Asia, and sub-Saharan Africa are employed in this sector. OBJECTIVE: To develop a costing methodology framework to assess the financial feasibility, at the national level, of implementing a maternity cash transfer for informally employed women. METHODS: A World Bank costing methodology was adapted for estimating the financial need to establish a maternity cash transfer benefit. The methodology estimates the cash transfer's unitary cost, the incremental coverage of the policy in terms of time, the weighted population to be covered, and the administrative costs. The 6-step methodology uses employment and sociodemographic data that are available in many countries through employment and demographic surveys and the population census. The methodology was tested with data for Mexico assuming different cash transfer unitary costs and the benefit's time coverage. RESULTS: The methodological framework estimated that the annual financial needs of setting up a maternity cash transfer for informally working women in Mexico ranges between US$87 million and US$280 million. CONCLUSIONS: A pragmatic methodology for assessing the costs of maternity cash transfer for informally employed women was developed. In the case of Mexico, the maternity cash transfer for women in the informal sector is financially feasible.

The healthy migrant effect: new findings from the Mexican Family Life Survey.

OBJECTIVES: We used nationally representative longitudinal data from the Mexican Family Life Survey to determine whether recent migrants from Mexico to the United States are healthier than other Mexicans. Previous research has provided little scientific evidence that tests the "healthy migrant" hypothesis. METHODS: Estimates were derived from logistic regressions of whether respondents moved to the United States between surveys in 2002 and 2005, by gender and urban versus rural residence. Covariates included physical health measurements, self-reported health, and education measured in 2002. Our primary sample comprised 6446 respondents aged 15 to 29 years. RESULTS: Health significantly predicted subsequent migration among females and rural males. However, the associations were weak, few health indicators were statistically significant, and there was substantial variation in the estimates between males and females and between urban and rural dwellers. CONCLUSIONS: On the basis of recent data for Mexico, the largest source of migrants to the United States, we found generally weak support for the healthy migrant hypothesis.

La migración como determinante de la obesidad infantil en Estados Unidos y Latinoamérica.

La migración internacional tiene consecuencias económicas y en la salud. El proceso de aculturación en el país de acogida puede estar relacionado con la obesidad infantil. Utilizamos el marco conceptual del balance energético comunitario (CEB, por sus siglas en inglés) para analizar la relación entre migración y obesidad infantil en los hogares mexicanos con migrantes internacionales. Utilizando datos longitudinales de la Encuesta Nacional de Niveles de Vida de los Hogares de México (ENNViH), examinamos cómo influyen las redes de migrantes sobre la obesidad infantil en las comunidades de origen. También revisamos programas de salud binacionales que podrían ser eficaces para abordar la obesidad infantil en los hogares de migrantes procedentes de México. Los niños que forman parte de las redes de migrantes presentan un mayor riesgo de -desarrollar sobrepeso y obesidad, lo cual sugiere una relación significativa entre la obesidad infantil y la migración internacional en los hogares mexicanos. Basándonos en los criterios de búsqueda que habíamos definido, realizamos un análisis de programas de extensión comunitaria en salud cuyos resultados indican que las Ventanillas de Salud (VDS) son una opción prometedora para prevenir la obesidad infantil en un entorno de confianza y culturalmente sensible. El marco conceptual CEB es útil para comprender cómo contribuye la migración al riesgo de sobrepeso y obesidad infantil en los hogares de los migrantes. Las VDS son una estrategia viable y replicable con un gran potencial para abordar la obesidad infantil entre las familias migrantes y que toma en cuenta los determinantes dinámicos y binacionales de la obesidad infantil.

After spouses depart: emotional wellbeing among nonmigrant Mexican mothers.

Nonmigrant family members play a central role in facilitating Mexico-U.S. migration by maintaining families, sustaining social relationships, and overseeing household economic organization in sending communities. This study investigates changes to the emotional wellbeing of nonmigrant mothers when their partners reside in the United States. We hypothesize that partner migration affects mothers' wellbeing through three pathways: directly via the toll of spousal separation, and indirectly via changes to the economic profile of the sending household and through changes to mothers' household responsibilities. We test these relationships using data on 2813 mothers aged 18-44 in 2002 and measured in three waves (2002, 2005, 2009) of the Mexican Family Life Survey. We employ a fixed-effect estimation strategy that improves causal attribution of women's wellbeing to spousal residential location. We find evidence of increases in some forms of distress-sadness, crying, difficulty sleeping-when spouses are in the United States but no meaningful increase in depressive symptomology. Though partner emigration shifts several aspects of women's lives in sending households, changes to household resources or time allocation do not account for the moderate shifts in emotional duress associated with spousal absence. Importantly, additional tests reveal that we would observe large and significant associations between spousal migration and mothers' emotional wellbeing using a less rigorous estimation strategy, raising caution about the interpretation of cross-sectional studies evaluating wellbeing in sending homes.

The role of maternal cognitive ability on child health.

Little is known about the mechanisms through which mother's cognitive ability operates in enhancing her children's health. This paper analyzes how maternal returns to cognitive ability on children's height reflect contemporaneous endowments and childhood background of the mother. Results suggest that maternal returns to cognitive ability on child height are less likely to reflect observed mother's childhood endowments as measured by parental transmission of knowledge or school quality, but are more likely to be associated with learning to be a mother, and with a better capacity to take advantage of household and community available resources.

The consequences of migration to the United States for short-term changes in the health of Mexican immigrants.

Although many studies have attempted to examine the consequences of Mexico-U.S. migration for Mexican immigrants' health, few have had adequate data to generate the appropriate comparisons. In this article, we use data from two waves of the Mexican Family Life Survey (MxFLS) to compare the health of current migrants from Mexico with those of earlier migrants and nonmigrants. Because the longitudinal data permit us to examine short-term changes in health status subsequent to the baseline survey for current migrants and for Mexican residents, as well as to control for the potential health selectivity of migrants, the results provide a clearer picture of the consequences of immigration for Mexican migrant health than have previous studies. Our findings demonstrate that current migrants are more likely to experience recent changes in health status-both improvements and declines-than either earlier migrants or nonmigrants. The net effect, however, is a decline in health for current migrants: compared with never migrants, the health of current migrants is much more likely to have declined in the year or two since migration and not significantly more likely to have improved. Thus, it appears that the migration process itself and/or the experiences of the immediate post-migration period detrimentally affect Mexican immigrants' health.
