Global differences in geography, religion and other societal factors are associated with sex differences in mortality from suicide: An ecological study of 182 countries

© 2019 Background: Over 800,000 individuals die as a consequence of suicide annually, and almost two thirds of these deaths are in males. This analysis aimed to explore sex differences in global suicide rates with regards to geographic location, religion and other societal factors. Methods: Data on sex-specific suicide rates were collated for 182 countries in 2015. The exposures of interest were geographical location, majority religion, life expectancy, total fertility rate (TFR), literacy percentage, gender development index and gross domestic product. Results: Both continent and predominant religion were strongly associated with the male:female ratio for deaths from suicide (p < 0.001 for both variables). The highest male:female suicide ratio was observed in the Americas with a median value of 4.0 (interquartile range IQR: 3.0–5.0) and the lowest gender suicide ratios were observed in Africa (2.7, IQR: 2.4–3.3) and Asia (2.7, IQR: 1.8–3.9). The predominantly Christian countries revealed the highest male:female suicide ratio (3.3, IQR: 2.7–4.4) whereas the predominantly Hindu countries revealed the lowest (1.3, IQR 1.3–3.8). The following variables were all positively associated with male:female ratio of suicide mortality: Life expectancy (Spearman's correlation coefficient r = +0.21, p = 0.004), GDP per capita (r = +0.26, p = 0.003), literacy percentage (r = +0.46, p < 0.0001), and Gender Development Index (r = +0.56, p < 0.0001). TFR was negatively associated with sex suicide ratio (–0.30, p < 0.0001). Conclusion: There are significant differences between male and female suicide rates across continents and cultures. Markers of societal development are associated with a higher proportion of male suicides compared to females

Weight, height, and midupper arm circumference are associated with haemoglobin levels in adolescent girls living in rural India: A cross‐sectional study

We aimed to explore the association of physical parameters with haemoglobin (Hb) levels to test the hypothesis that impaired physical development is associated with anaemia. A cross‐sectional survey study recruited adolescent girls (13 to 17 years) living in rural areas of Maharashtra state of India. Data were collected on physical parameters include height, weight, and midupper arm circumference (MUAC). Hb levels were measured using Sahli's haemometer. Linear regression was conducted to test the hypothesis. Data were collected from 1,010 girls on physical parameter and Hb levels. The majority of the adolescent girls were diagnosed with anaemia (87%). The regression analysis adjusted for age gave a significant association of Hb levels with all three variables (MUAC, weight, and height). Hb increased by 0.11 g/dl with an each centimetre of increase in MUAC (95% confidence interval, CI, [0.08, 0.15], P < .001). Each kilogram of increase in the body weight showed an increase in Hb levels (0.02 g dl, 95% CI [0.01, 0.03], P = .001). With an each centimetre of increase in height, Hb increased by 0.01 g dl (95% CI [0.00, 0.02], P = .022). There was a consistent association between three measures of somatic growth and anaemia in the study population. It is likely that life‐course exposures from conception onwards contribute to this, and the public health implications are that preventing anaemia is a challenge that requires a multifaceted interventional approach. Understanding the importance of the timing of these life exposures will help design interventions that can achieve optimal results

Association of socioeconomic status with sex ratio at live birth in individuals living in the slums of Sholapur city, India

Background: The existence of female feticide in India is well known. However, limited data are available on the association of socioeconomic status (SES) on sex ratio at live birth in disadvantaged populations, despite the fact that 33% of the population of India live on less than $1.25 per day. Objective: To study the association of SES with sex ratio at live birth in individuals living in the slums of Sholapur city, India. Materials and Methods: We used the data collected as a part of a social work intervention in the slums of Sholapur city, Maharashtra, from January 2007 to August 2011. Two measures of SES were used, location of birth (government hospital compared to private hospital) and eligibility for means-tested financial support after delivery. Results: Data were available for 1391 infants. The infants born in government hospitals were more likely to be male compared to those born in private hospitals (sex ratio of 1.45 compared to 1.14, respectively, p = 0.03). Similarly, infants whose parents were eligible for post-delivery financial support had a trend to a higher sex ratio (1.47 compared to 1.18, p = 0.057). Maternal age was independently and inversely associated with sex ratio at live birth with a linear relation (OR per year increase in maternal age 0.96, 95% CI 0.93–1.00, p = 0.03). Conclusion: In this particular population, two measures of less affluent SES were associated with higher sex ratio at live birth. However, care should be taken while generalizing these observations to other disadvantaged groups living in India, but this represents an area of research where more epidemiological work is required, as these differences perpetuated over generations may have substantial demographic consequences

Healthcare benefits linked with Below Poverty Line registration in India: Observations from Maharashtra Anaemia Study (MAS)

A 2015 Lancet paper by Patel et al. on healthcare access in India comprehensively discussed national health programmes where some benefits are linked with the country’s Below Poverty Line (BPL) registration scheme. BPL registration aims to support poor families by providing free/subsidised healthcare. Technical issues in obtaining BPL registration by poor families have been previously reported in the Indian literature; however there are no data on family assets of BPL registrants. Here, we provide evidence of family-level assets among BPL registration holders (and non-BPL households) using original research data from the Maharashtra Anaemia Study (MAS). Social and health data from 287 pregnant women and 891 adolescent girls (representing 1178 family households) across 34 villages in Maharashtra state, India, were analysed. Several assets were shown to be similarly distributed between BPL and non-BPL households; a large proportion of families who would probably be eligible were not registered, whereas BPL-registered families often had significant assets that should not make them eligible. This is likely to be the first published evidence where asset distribution such as agricultural land, housing structures and livestock are compared between BPL and non-BPL households in a rural population. These findings may help planning BPL administration to allocate health benefits equitably, which is an integral part of national health programmes

Concerns about covert HIV testing are associated with delayed presentation of suspected malaria in Ethiopian children: a cross-sectional study

BACKGROUND Early diagnosis is important in preventing mortality from malaria. The hypothesis that guardians' fear of covert human immunodeficiency virus (HIV) testing delays presentation of children with suspected malaria was tested. METHODS The study design is a cross-sectional survey. The study population consisted of guardians of children with suspected malaria who presented to health centres in Oromia Region, Ethiopia. Data were collected on attitudes to HIV testing and the duration of children's symptoms using interview administered questionnaires. RESULTS Some 830 individuals provided data representing a response rate of 99% of eligible participants. Of these, 423 (51%) guardians perceived that HIV testing was routinely done on blood donated for malaria diagnosis, and 353 (43%) were aware of community members who delayed seeking medical advice because of these concerns. Children whose guardians suspected that blood was covertly tested for HIV had longer median delay to presentation for evaluation at health centres compared to those children whose guardians did not hold this belief (three days compared to two days, p < 0.001). Children whose guardians were concerned about covert HIV testing were at a higher odds of a prolonged delay before being seen at a health centre (odds ratio 1.73, 95% confidence intervals: 1.10 to 270 for a delay of ≥ 3 days compared to those seen in ≤ 2 days). CONCLUSION Children whose guardians believed that covert testing for HIV was routine clinical practice presented later for investigation of suspected malaria. This may account for up to 14% of the delay in presentation and represents a reversible risk factor for suboptimal management of malaria

Rate of improvement of CF life expectancy exceeds that of general population: observational death registration study

Background: It is unclear why cystic fibrosis (CF) survival has improved. We wished to quantify increases in CF median age of death in the context of general population survival improvement. Method: Death registration data analysis (US, England & Wales (E&W)—1972–2009). Results: CF median age of death is higher in US than E&W and greater for males, opposite to that of death from all causes. CF median age of death has increased by 0.543 life years per year (E&W, US combined (95% confidence interval 0.506, 0.582)). The difference in median age at death between those dying from all causes and CF decreased in both territories. CF median age of death for males is greater than for females in both territories. This gap has not narrowed. Conclusion: The median age of death of people with CF is improving more rapidly than that of the general population in US and E&W
