In India, progress against undernutrition has been slow. Given its importance for income generation, improving diets, care practices, and maternal health, the agriculture sector is widely regarded as playing an important role in accelerating the reduction in undernutrition. This paper comprehensively maps existing evidence along agriculture-nutrition pathways in India and assesses both the quality and coverage of the existing literature. We present a conceptual framework delineating six key pathways between agriculture and nutrition. Three pathways pertain to the nutritional impacts of farm production, farm incomes, and food prices. The other three pertain to agriculture-gender linkages. After an extensive search, we found 78 research papers that provided evidence to populate these pathways. The literature suggests that Indian agriculture has a range of important influences on nutrition. Agriculture seems to influence diets even when controlling for income, and relative food prices could partly explain observed dietary changes in recent decades. The evidence on agriculture-gender linkages to nutrition is relatively weak. Sizeable knowledge gaps remain. The root causes of these gaps include an interdisciplinary disconnect between nutrition and economics/agriculture, a related problem of inadequate survey data, and limited policy-driven experimentation. Closing these gaps is essential to strengthening the agriculture sector's contribution to reducing undernutrition. [ABSTRACT FROM AUTHOR]

Adolescent motherhood has been linked with poor health outcomes at birth for children, including high neonatal mortality, low birthweight, and small‐for‐gestational‐age rates. However, longer‐term growth outcomes in the children of adolescent mothers in low‐resource settings remain inadequately studied. We used longitudinal data from the India Human Development Surveys, 2004–2005 and 2011–2012 (n = 12,182) and employed regression and propensity score matching analysis to compare the following growth indicators of children born to adolescent mothers (ages 19 years or below) with those born to older mothers. Growth indicators included height and weight during ages 0–5 years and 6–12 years and change in height and weight between the two periods. In regression‐based estimates, children born to adolescent mothers were 0.01 m shorter and weighed 0.2 kg less than children of older mothers at ages 0–5 years. At ages 6–12 years, those born to adolescent mothers were 0.02 m shorter and weighed 0.97 kg less. The height difference between the two groups increased by 0.01 m and the weight difference grew by 0.77 kg over time. Height and weight difference between the two groups worsened among boys over time, while for girls, only the weight gap worsened. The results were similar when using propensity score matching methods. Public policies for reducing child marriage, combined with targeted health, nutrition, and well‐being programs for adolescent mothers, are essential for both preventing adolescent childbearing and reducing its impact on growth failure among children in India.

Increased concern over the adverse health effects of air pollution has highlighted the need for air-pollution measurements, especially in urban areas, where many sources of air pollutants are normally monitored outdoors as part of obligations under the National Air Quality Strategies. Very little is known about air pollution indoors. In fact, the largest exposure to health-damaging indoor pollution probably occurs in the developing world, not in households, schools, and offices of developed countries where most research and control efforts have been focused to date. As a result much of the health impacts from air pollution worldwide seem to occur among the poorest and most vulnerable populations. The authors in their earlier studies have confirmed the importance of ambient air in determining the quality of air indoors. In this study an observation of air quality indoors and outdoors of domestic homes located in an urban environment from October 2004 to December 2005 in Agra, north central India, is performed. The purpose of this study was to characterize the indoor/outdoor (I/O) relationship of airborne pollutants and recognize their probable source in all three seasons, that is, winter, summer, and rainy season. Concentrations of SO2, NO2, CO2, Cl2, H2S, NH3, RSPM, and PAH were monitored simultaneously and I/O ratios were calculated. In order to investigate the effect of seasonality on indoor and ambient air quality, winter to summer and winter to monsoon average ratios were calculated. It is apparent that there is a general pattern of increasing levels from monsoon to summer to winter, and similarly from outdoor to indoor air. Regressions analysis had been done to further investigate the influence of outdoor air-pollutant concentrations on indoor concentrations. The most probable categories of sources for these pollutants have been identified by using principal-component analysis. Indoor air pollution is a complex function of energy housing and behavioral factors. On the basis of this study and observations, some interventions are also suggested. [ABSTRACT FROM AUTHOR]
