Hindus and Muslims together account for 94% of the population of India. The fertility differential between these two religious groups is a sensitive and hotly debated issue in political and academic circles. However, the debate is mostly based on a period approach to fertility change, and there have been some problems with the reliability of period fertility data. This study investigated cohort fertility patterns among Hindus and Muslims and the causes of the relatively higher level of fertility among Muslims. Data from the three National Family Health Surveys conducted in India since the early 1990s were analysed using a six-parameter special form of the Gompertz model and multiple linear regression models. The results show a gap of more than 1.3 children per woman between those Muslim and Hindu women who ended/will end their reproductive period in the calendar years 1993 to 2025. The socioeconomic and demographic characteristics of Muslims explain 31.2% of the gap in fertility between Muslims and Hindus, while the desire for more children among Muslims explains an additional 18.2% of the gap in fertility.

Intra-population socioeconomic changes and migration are powerful factors in changing eating habits. Changes in eating habits could affect the nutritional status, growth, development and health of adolescents. The aim of this study was to compare the diet of adolescents of Moroccan origin living in Spain with that of adolescents living in Morocco. The sample comprised 428 Moroccan adolescents aged from 12 to 19 recruited in high schools: 327 living in Ouarzazate (Morocco) and 101 living in Madrid (Spain). The variables studied were energy intake (kcal/day), diet quality indicators (adherence to the Mediterranean Adequacy Index (MAI); cholesterol intake (mg/day); fibre intake (g/day) and energy profile)); and indicators of keeping traditional customs (halal meat consumption, bread made at home). Teenagers from Morocco living in Madrid consumed more calories, proteins, saturated fats and simple sugars (p<0.001) than those living in Morocco. Their diet was of lower quality than that of their peers in Morocco. This difference was more marked in boys than in girls. Changes in eating habits associated with migration from the south to the north Mediterranean basin can benefit young migrants in an immediate way (through greater availability of energy and nutrients), but later in life it could have negative consequences for their health, increasing the risk of overweight, obesity and cardiovascular and metabolic problems.

This study used data from the 2008 Ghana Demographic and Health Survey to investigate the association between selected socio-demographic factors and dietary behaviour as measured by fruit and vegetable consumption among a sample of 6139 young people aged 15–34 years in Ghana. Overall, fruit and vegetable consumption was low in young people, but females were likely to consume more fruit and vegetables than their male counterparts. Respondents from the Mande ethnic group, those who resided in rural areas and those living in the Brong/Ahafo, Ashanti and the Eastern regions consumed more fruit and vegetables than those from other regions. Females who were Catholic/Anglican, Methodist/Presbyterian and Pentecostal/Charismatic were more likely than those of other religions to consume fruit and vegetables, while Muslim males generally consumed more fruit and vegetables. The findings point to the need for interventions to educate young people in Ghana about the health benefits of eating fruit and vegetables.

This study examined the relationship between Intimate Partner Violence (IPV) and unintended pregnancy among young women in South Asia using Demographic and Health Survey data from India (2005–2006), Bangladesh (2007) and Nepal (2011). The respondents were adolescent and young adult married women aged 15–24 years who had at least one childbirth in the five years preceding the survey. Bivariate and stepwise multivariate logistic regression analyses were performed to assess the relationship between IPV and unintended pregnancy. Thirty-eight per cent of the respondents in India, 52% in Bangladesh and 28% in Nepal reported having experienced physical or sexual IPV. Those who reported physical or sexual IPV had higher odds of unintended pregnancy (1.36 in India and 1.99 in Bangladesh). The findings indicate that IPV is a risk factor for unintended pregnancy among adolescent and young adult married women. Along with violence prevention programmes, a more responsive and youth-friendly health system needs to be in place to provide health care services to young women in these countries.

The nutritional status of under-five-year-old children is a sensitive indicator of a country’s health status as well as economic condition. The objectives of this study were to analyse trends in the nutritional status in Bangladeshi children over the period 1996–2007 and to examine the associations between nutritional and socioeconomic status variables. Bangladesh Demographic Health Surveys (BDHS) were the source of data, and a total of 16,278 children were examined. The Z-scores of the children were analysed as continuous as well as categorical variables (stunted, underweight and wasted). The socioeconomic status variables used were region, urban–rural residence, education and occupation of the parents, house type and household possession score. A series of General Linear Model and Sequential Linear and Binary Logistic Regression analyses were done to assess the relationship between demographic and socioeconomic variables and nutritional status. The trends of Z-scores were analysed by survey, as well as by child birth cohort. Region, house type, educational level of parents and household possession score showed significant associations with all three Z-scores of children after removing the effects of age, period of DHS and other explanatory variables in the model. No significant sex difference was observed between any of the Z-scores. There were improvements in mean WAZ and HAZ between 1996 and 2007 but deterioration in mean WHZ over this period. The obesity rate was below 2% in 2007, although the absolute numbers of obese children had nearly doubled in this 12-year period. Children from poorer households showed greater improvement than their better-off counterparts. The study reveals that over the years there has been substantial improvement in nutritional status of under-five children in Bangladesh and the main gains have been amongst the lower socioeconomic groups; it is also evident that malnutrition in Bangladesh is a multidimensional problem, like poverty itself, and warrants a proper policy mix and programme intervention.

This study confirms an association between survival probability of becoming a centenarian (SPBC) for those aged 65 to 69 and country-level socioeconomic indicators in Europe: the gender inequality index (GII), male labour force participation (MLP) rates and proportions of seats held by women in national parliaments (PWP). The analysis was based on SPBC data from 34 countries obtained from the United Nations (UN). Country-level socioeconomic indicator data were obtained from the UN and World Bank databases. The associations between socioeconomic indicators and SPBC were assessed using correlation coefficients and multivariate regression models. The findings show significant correlations between the SPBC for women and men aged 65 to 69 and country-level socioeconomic indicators: GII (r=−0.674, p=0.001), MLP (r=0.514, p=0.002) and PWP (r=0.498, p=0.003). The SPBC predictors for women and men were lower GIIs and higher MLP and PWP (R 2=0.508, p=0.001). Country-level socioeconomic indicators appear to have an important effect on the probability of becoming a centenarian in European adults aged 65 to 69. Country-level gender equality policies in European counties may decrease the risk of unhealthy old age and increase longevity in elders through greater national gender equality; disparities in GII and other country-level socioeconomic indicators impact longevity probability. National longevity strategies should target country-level gender inequality.

This cross-sectional study was carried out to capture possible maternal factors affecting newborns’ anthropometric measurements. Data were collected from eight public health centres and referral university hospital records in Tabriz and Heriss districts, north-west Iran, for 807 mother–neonate pairs delivering live singleton births and their offspring during the two years up to August 2014. The incidence of low birth weight (LBW) was 5.1%. A close correlation was found between maternal anthropometry and birth order with neonatal anthropometric data. Birth order and maternal height and body mass index (BMI) positively affected neonates’ birth size (weight, length and head circumference). The rate of LBW was significantly higher for older (≥35 years), taller (≥170 cm), underweight (BMI<18.5) and non-iron-taking women and in the first-born babies. The odds of having LBW newborns in older, taller, underweight, obese and irregular iron-taking women were 3.82, 4.00, 9.07, 3.50 and 2.50 times those of mid-age group, middle-height, overweight and regular iron-taking women, respectively. First-born newborns were 5.97 times more likely to be LBW compared with second-birth neonates. The results indicate that maternal anthropometric indices, age, iron intake and birth order influence the risk of LBW in newborns.

A majority of Zambian children live in impoverished communities that lack safe water and proper sanitation, exposing them to urogenital and intestinal helminths. Efforts to mitigate this plight have been implemented through mass drug administration aimed at deworming school-age and under-five children against schistosomiasis and soil-transmitted helminths. However, the disease status of adults living in the same communities as the treated children remains unknown. The aim of this study was to describe the potential contribution of infected adult populations to the transmission of these infections in southern Zambia. A cross-sectional study was conducted in April and May 2013 as part of baseline survey for a larger study in Mazabuka and Siavonga Districts. Stool and urine samples of 2829 adults from five catchment areas were collected and processed using Kato-Katz and urine filtration methods, respectively. Adults from Siavonga had a 13.9% combined prevalence of Schistosoma haematobium and S. mansoni, and 12.1% combined prevalence of Ascaris lumbricoides and hookworm. There was no S. mansoni in Mazabuka, and only a 5.3% prevalence of S. haematobium and 7.4% combined prevalence of A. lumbricoides and hookworm. Additionally, no Trichuris trichiura infections were observed in the two districts. Despite most of these infections being categorized as light intensity, heavy infection intensities were also found for all four parasite species. If this infected adult population is left untreated, the possibility of it acting as a reservoir of infections and ultimately transmitting the infections to treated children remains. Therefore, there is need to consider alternative treatment strategies that incorporate adults, thereby reducing the risk of contaminating the environment and perpetuating transmission to children.

This study was based on two independent studies which in total consisted of 1812 school pupils aged 6–12 years in Saudi Arabia. Study I consisted of 1591 school pupils (609 boys and 982 girls) attending state schools, and Study II consisted of 211 boys with learning disabilities. Intelligence (measured using the Standard Progressive Matrices Plus for Study I and the Standard Progressive Matrices for Study II), head size and height were measured for the two samples. The results showed that intelligence was statistically significantly correlated with head circumference (r=0.350, p<0.001 for Study I and r=0.168, p<0.05 for Study II) and height (r=0.271, p<0.001 for Study I and r=0.178, p<0.05 for Study II).
