Nutritional impairment during adolescence may result in adverse physical and reproductive health outcomes. We investigated the prevalence and determined the factors associated with underweight and overweight/obesity among ever-married adolescent girls in Bangladesh. We used Bangladesh Demographic and Health Surveys data conducted in 2004, 2007, 2011, 2014, and 2017. A total of 7040 ever-married adolescent girls aged 15-19 years were included in this analysis. Prevalence of underweight (body mass index [BMI]<18.5 kg/m²) significantly decreased from 39.53% (95% CI = 36.71, 42.43) to 23.62% (95% CI = 21.35, 26.05) during 2004-2017 (p < 0.001). However, prevalence of overweight/obesity (BMI ≥ 23 kg/m²) significantly increased from 5.9% (95% CI = 4.67, 7.43) to 22.71% (95% CI = 20.39, 25.20) during the same period (p < 0.001). The girls with higher age (OR = 0.94, 95% CI = 0.90, 0.99, p = 0.023), higher level of education (OR = 0.60, 95% CI = 0.43, 0.83, p = 0.002), and richest wealth quintile (OR = 0.78, 95% CI = 0.62, 0.98, p = 0.035) had significantly lower risk of being underweight. Adolescent girls having more than one child (OR = 1.41, 95% CI = 1.15, 1.73, p = 0.001) were more likely to be underweight. Elderly adolescents with better economic status were more at risk of being overweight/obese (OR = 2.57, 95% CI = 1.86, 3.55, p < 0.001). Girls married to skilled/unskilled workers (OR = 0.58, 95% CI = 0.44, 0.77, p < 0.001) and persons involved in small businesses (OR = 0.66, 95% CI = 0.49, 0.89, p = 0.007) had lower risk of having a high BMI. Using contraceptive (OR = 0.8, 95% CI = 0.69, 0.94, p = 0.006) was negatively associated with overweight/obese. Although prevalence of undernutrition among ever-married adolescent girls is declining, the proportion of being overweight/obese is increasing in Bangladesh warranting effective strategies to improve adolescent nutrition.

In India, undernutrition among children has been extremely critical for the last few decades. Most analyses of undernutrition among Indian children have used the administrative boundaries of a state or a district level as a unit of analysis. This paper departs from such a practice and focuses instead on the political boundaries of a parliamentary constituency (PC) as the unit of analysis. The PC is a critical geopolitical unit where political parties and party candidates make election promises and implement programmes to improve the socio-economic condition of their electorate. A focus on child undernutrition at this level has the potential for greater policy and political traction and could lead to a paradigm shift in the strategy to tackle the problem by creating a demand for political accountability. Different dimensions and new approaches are also required to evaluate the socio-economic status and generate concrete evidence to find solutions to the problem. Given the significance of advanced analytical methods and models embedded into geographic information system (GIS), the current study, for the first time, uses GIS tools and techniques at the PC level, conducting in-depth analysis of undernutrition and its predictors. Hence, this paper examines the spatial heterogeneity in undernutrition across PCs by using geospatial techniques such as univariate and bivariate local indicator of spatial association and spatial regression models. The analysis highlights the high-low burden areas in terms of local hotspots and identifies the potential spatial risk factors of undernutrition across the constituencies. Striking variations in the prevalence of undernutrition across the constituencies were observed. Most of these constituencies that performed poorly both in terms of child nutrition and socio-economic indicators were located in the northern, western, and eastern parts of India. A statistically significant association of biological, socio-economic, and environmental factors such as women's body mass index, anaemia in children, poverty, household sanitation facilities, and institutional births was established. The results highlight the need to bring in a mechanism of political accountability that directly connects elected representatives to maternal and child health outcomes. The spatial variability and pattern of undernutrition indicators and their correlates indicate that priority setting in research may also be greatly influenced by the neighbourhood association.

The aim of this study was to understand the perspectives of female residents of Spain from West Africa in terms of the factors that condition their lives. Pierre Bourdieu's theory and the model of intersectionality formed the framework we used to qualitatively analyse the life stories of these women, which was complemented with life lines. The results showed us that traditional practices such as female genital mutilation and forced marriage are part of the social habitus of this group and they relate to each other through the several types of violence that occurs throughout their lives. In addition, in reference to the African community, these women were no longer African, while in terms of the Spanish community, they did not seem Spanish. At a health, political, and social level, this knowledge can help us to understand this group and to create personalised targeted interventions for them.

India has not only maintained its top position among countries with the largest number of underweight adults but has also jumped to a higher position among countries with largest increase in the proportion of overweight people in the last three decades. More studies focus on double burden of malnutrition among women than on men. This study uses the quantile regression model to analyse the covariates associated with low and high body mass index (BMI) primarily among men aged 20-54 years during 2015-2016 in India. Occupations that involve more manual work help in maintaining a normal BMI along with better education, dietary diversity, and less sedentary lifestyle. A gendered comparison of men and their spouses highlights the differences in the association of covariates with BMI for men and women. The results from this study will provide insights for behavioural change at an individual level and inputs for public health intervention for addressing ill health concerns arising from underweight, overweight, or obesity.

Numerous studies have confirmed the relationship between individual risk and time preference and obesity. Nevertheless, none has studied the effect of these attitudes on chronic (long-term) obesity. This study used Indonesia Family Life Survey (IFLS) data from 16,366 individuals. It tracked their obesity status in 2007 and 2014 by calculating body mass index, the ratio between body weight and square of height. Besides the conventional risk-averse and risk-tolerant behaviour, the IFLS sample includes people who fear uncertainty related to the status quo bias. The ordered logit regression results show that past impatience, risk tolerance, and status quo bias behaviour (in 2007) are associated with transient or chronic obesity, while only current behaviour of status quo bias (in 2014) is associated with obesity. Furthermore, our study confirms that chronic obesity in Indonesia is prevalent among highly educated, high-income, and urban-centric individuals, exacerbated by impatience, risk tolerance, and uncertainty aversion. Thus, providing information on the risk of obesity and food calories, giving the incentive to avoid obesity, and improving the quality of built environments such as public parks, public transportation, and footpath could help prevent the rising obesity prevalence.

Weight abnormalities (underweight, overweight, and obesity) can cause life-threatening ailments. This study investigates disparities in the prevalence of underweight, overweight, and obesity between northern and southern Nigeria and their associated factors. Using the 2018 Nigeria Demographic and Health Survey (NDHS), the study analysed a sample of 12,333 women with complete records of body mass index. The study found that southern women had lower odds of being underweight than women in the north, but the reverse was the case for overweight and obesity. The prevalence of underweight was 11.6%, and it varies from 6.9% in the southern state of Enugu to 31.6% in the northern state of Jigawa. The national prevalence of overweight was 17.9%, ranging from 6.7% in Jigawa State of the northern region to 39.9% in Lagos State of the south. Similarly, the prevalence of obesity in the north was 6.1% compared to 14.4% in the south, with Anambra State of the southern region recording the highest figure of 35.5% compared to 2.1% in the Yobe State of the northern region. In all, the rate of abnormal weight was significantly higher in the south than in the north. However, the type of weight abnormality varies between the two regions. Religion, education, use of contraceptives, and wealth were associated with the three forms of abnormal weights. However, while religion was significantly associated with obesity in the north, the association was not significant in the south. This study found that wealth and education have dissimilar influences on overnutrition. While the odds of being overweight and obese increase with wealth, being educated up to a secondary level significantly reduces the odds in Nigeria and across the two regions.

A barrier to meeting the goal of universal health coverage in India is the inequality in utilisation of health services between indigenous and non-indigenous people. This study aimed to explore the determinants of utilisation, or non-utilisation, of public healthcare services among the Santals, an indigenous community living in West Bengal, India. The study holistically explored the utilisation of public healthcare facilities using a framework that conceptualised service coverage to be dependent on a set of determinants – viz. the nature and severity of the ailment, availability, accessibility (geographical and financial), and acceptability of the healthcare options and decision-making around these further depends on background characteristics of the individual or their family/household. This cross-sectional study adopts ethnographic approach for detailed insight into the issue and interviewed 422 adult members of Santals living in both rural (Bankura) and urban (Howrah) areas of West Bengal for demographic, socio-economic characteristics and healthcare utilisation behaviour using pre-tested data collection schedule. The findings revealed that utilisation of the public healthcare facilities was low, especially in urban areas. Residence in urban areas, being female, having higher education, engaging in salaried occupation and having availability of private allopathic and homoeopathic doctors in the locality had higher odds of not utilising public healthcare services. Issues like misbehaviour from the health personnel, unavailability of medicine, poor quality of care, and high patient load were reported as the major reasons for non-utilisation of public health services. The finding highlights the importance of improving the availability and quality of care of healthcare services for marginalised populations because these communities live in geographically isolated places and have low affordability of private healthcare. The health programme needs to address these issues to improve the utilisation and reduce the inequality in healthcare utilisation, which would be beneficial for all segments of Indian population.

Context: The effect of health insurance coverage on sexual and reproductive health, especially unintended pregnancy, has scantly been researched. Using the 2014 Ghana Demographic and Health Survey, the study examined the links between women's health insurance enrolment on unintended pregnancy in Ghana.

Method: The sample consisted of 9,396 women aged 15-49 years, but the analysis was limited to the 4,544 women who were pregnant in the two years preceding the survey. The effects of health insurance enrolment on unintended pregnancy was examined with the propensity score matching. The health insurance enrolment was the treatment variable and unintended pregnancy as the outcome variable.

Results: This study showed that 66.0% of all women surveyed had health insurance coverage and 31.8% of all women of childbearing age who were currently or had previously been pregnant reported having at least one unintended pregnancy. Thirty percent of insured women had an unintended pregnancy, compared to 37% of uninsured women. The results showed that education, household wealth index, religion, and type of marital union were significant predictor of health insurance coverage among Ghanaian women. The PSM split the women based on their health insurance status. After matching, the difference between the insured and uninsured women reduces significantly. Results demonstrated that, the probability of unintended pregnancy was 0.312 among insured women and 0.351 among those not insured in Ghana. This implies that having health insurance coverage will help in reducing the likelihood of women experiencing unintended pregnancy.

Conclusions: Results highlight the importance of the target of universal health coverage under the sustainable development goal 3 and demonstrate that expanding existing health insurance schemes within Ghana could contribute to reducing the number unintended pregnancies experienced each year.

This paper presents the first evidence of the causal relationship between adult children's schooling and changes in parental health in the short and long term. By using supply-side variation in schooling as an instrument for adult children's education and a representative dataset for rural China, we find that adult children' education has a positive influence on the long-term changes in parental health, with limited evidence of any short-term effect. Our results remain consistent after a variety of sensitivity tests. The heterogeneous analyses show differences in socio-economic status and gender, with low-educated parents and mothers being the primary beneficiaries of children's schooling. Potential mechanisms for the long-term effects of adult children's education on changes in parental health include better chronic disease management, improved access to health, sanitation, and clean fuel facilities, improved psychological well-being, and reduced smoking behaviours.

Blood pressure (BP) control is a key intervention to decrease cardiovascular diseases (CVD), the main cause of death in low and middle-income countries (MIC). Scarce data on the determinants of BP control in Latin America are available. Our objective is to explore the role of gender, age, education, and income as social determinants of BP control in Argentina, a MIC with a universal health care system. We evaluated 1184 persons in two hospitals. Blood pressure was measured using automatic oscillometric devices. We selected those patients treated for hypertension. The average BP of less than 140/90 mmHg was considered a controlled BP. We found 638 hypertensive individuals, of whom 477 (75%) were receiving antihypertensive drugs, and of those, 248 (52%) had controlled BP. The prevalence of low education was more frequent in uncontrolled patients (25.3% vs. 16.1%; P < .01). We did not find association between household income, gender, and BP control. Older patients had less BP control (44% of those older than 75 years vs. 60.9% of those younger than 40; test for trend P < .05). Multivariate regression indicates low education (OR 1.71 95% CI [1.05, 2.79]; P = .03) and older age (OR 1.01; 95% IC [1.00, 1.03]) as independent predictors of the lack of BP control. We conclude that rates of BP control are low in Argentina. In a MIC with a universal health care system low education and old age but not household income are independent predictors of the lack of BP control.
