There is a demonstrated link between intimate partner violence (IPV) and pregnancy termination, and this association has received much attention in developed settings. Despite the high prevalence of IPV in Papua New Guinea (PNG), little is known about the association between these experiences and pregnancy termination. This study examined the association between IPV and pregnancy termination in PNG. The present study used population-based data from the PNG's first Demographic and Health Survey (DHS) conducted in 2016-2018. The analysis involved women aged 15-49 years who were in intimate unions (married or co-habiting). We used binary logistic regression modelling to analyse the association between IPV and pregnancy termination. Results were reported as crude odds ratios (cOR) and adjusted odds ratios (aOR) with 95% confidence intervals (CIs). Overall, 6.3% of women involved in this study had ever terminated a pregnancy, and 6 in 10 women (61.5%) reported having experienced IPV in the last 12 months preceding the survey. Of those women who experienced IPV, 7.4% had ever terminated a pregnancy. Women who had experienced IPV had a 1.75 higher odds of reporting pregnancy termination (cOR: 1.75; 95% CI: 1.29-2.37) than women who did not experience IPV. After controlling for theoretically and empirically relevant socio-demographic and economic factors, IPV remained a strong and significant determinant of pregnancy termination (aOR: 1.67, 95% CI: 1.22-2.30). The strong association between IPV and pregnancy termination among women in intimate unions in PNG calls for targeted policies and interventions that address the high prevalence of IPV. The provision of comprehensive sexual reproductive health, public education, and awareness creation on the consequences of IPV, regular assessment, and referral to appropriate services for IPV may reduce the incidence of pregnancy termination in PNG.

Unmet need for family planning is a valuable concept to indicate the discrepancy between women's fertility preferences and contraceptive use. Unmet need may lead to unintended pregnancies and unsafe abortions. These may result in health deterioration and reduced employment opportunities for women. The 2018 Turkey Demographic and Health Survey report indicated that the estimated unmet need for family planning doubled from 2013 to 2018, returning to the high levels of the late 1990s. Considering this unfavourable change, this study aims to investigate the determinants of unmet need for family planning among married women of reproductive age in Turkey by using the 2018 Turkey Demographic and Health Survey data. Logit model estimations revealed that women who were at older ages, more educated, wealthier, and had more than one child were less likely to have unmet need for family planning. Employment statuses of women and their spouses and place of residence were significantly associated with unmet need. Results emphasised that training and counselling to enhance the use of family planning methods should effectively target young, less educated, and poor women.

The association between early reproductive events and health status in later life has always been of interest across disciplines. The purpose of this study was to investigate whether there was an association between the number of children born in the early years of elderly women and their depression in later life based on a sample of older women aged 65 years and above with at least one child in rural China. Data from the Chinese Longitudinal Healthy Longevity Survey in 2018, this study used the ordinary least square method to conduct empirical research. This study has found a significant correlation between an increase in the number of children and depression in older rural women. When considering the sex of the child, the number of daughters had a greater and more significant impact on depression. Number of children may exacerbate depression of older women through declining self-rated health and reduced social activity, while increased inter-generational support alleviated depression. The association between number of children born and depression also existed in urban older women, though not significant. Therefore, it is suggested to accelerate the improvement of supporting policies related to childbirth, developing a healthy and scientific fertility culture, and improving rural maternal and child health services. Women should be assisted in balancing their roles in the family and in society, and in particular in sharing the burden of caring for children. Targeted efforts to increase old-age protection for older people.

Functional health is arguably one of the most important health indicators for older adults, because it assesses physical, cognitive and social functions in combination. However, life-course circumstances may impact this multidimensional construct. The aim of the present study was to assess the relationship between life-course socio-economic status (SES) and different dimensions of functional health in older adults. Data on 821 Portuguese adults aged 50 years and over in 2013-2015 were analysed. Life-course SES was computed using participants' paternal occupation (non-manual (nm); manual (m)) and own occupation (nm; m), resulting in four patterns: stable high (nm + nm), upward (m + nm), downward (nm + m) and stable low (m + m). Functional health included physical and mental functioning, cognitive function, handgrip strength, and walking speed. Linear (beta coefficients) and logistic regressions (odds ratios) were used to estimate the association between life-course SES and functional health.Overall, those who accumulated social disadvantage during life-course presented worse functional health than those with stable high SES (stable low - SF-36 physical functioning: β = -9.75; 95% CI: -14.34; -5.15; SF-36 mental health: β = -7.33; 95% CI: -11.55; -3.11; handgrip strength: β = -1.60; 95% CI: -2.86; -0.35; walking time, highest tertile: OR = 5.28; 95% CI: 3.07; 9.09). Those with an upward SES were not statistically different from those in the stable high SES for most of the health outcomes; however, those with an upward SES trajectory tended to have higher odds of cognitive impairment (OR = 1.75; 95% CI: 0.96; 3.19). A downward SES trajectory increased the odds of slower walking speed (OR = 4.62; 95% CI: 1.78; 11.95). A disadvantaged life-course SES impacts older adults' physical and mental functioning. For some outcomes, this was attenuated by a favourable adulthood SES but those with a stable low SES consistently presented worse functional health.

An extensive body of demographic literature has described Jews as 'long-lifers'. From the mid-nineteenth century onwards, this pattern affected all age groups and was particularly well expressed among Jewish males but was also present among Jewish females. It held good independently of the Jews' socio-economic position. This became known as 'Jewish pattern of mortality'. This paper has two aims. The first aim is to show the impact of COVID-19 on Jewish mortality. This is a study of a global pandemic in the Jewish population which is, to the best of our knowledge, unique in its scope and quality. The second aim is to settle the finding of relatively high mortality from COVID-19 in certain Jewish communities ('Jewish penalty' in relation to COVID-19) with the notion of 'Jewish pattern of mortality'. The author proceeds to show that the status of Jews as a low mortality group under a Western epidemiological regime, when mortality and morbidity are dominated by non-communicable diseases, does not stand in contradiction to a higher vulnerability among Jews to coronavirus. Thus, the paper further develops understanding of mortality of Jews and serves as a contribution to ethnic and religious demography and epidemiology.

In Colombia, the prevalence of obesity has been increasing in recent years due to changes in dietary and nutritional patterns. While previous studies have focussed on describing obesity and its associated factors, they have mainly used a cross-sectional methodology. Accordingly, this study aims to conduct a descriptive quasi-cohort analysis to capture age-specific cohort trends in body mass index (BMI) according to sex and ethnicity (indigenous, Afro-Colombian, and the remaining population). The study utilised data from the National Survey of the Nutritional Situation in Colombia (ENSIN) conducted in 2005, 2010, and 2015 that included 214,136 individuals aged 20-64 years after screening. Data on ethnicity were only available from the 2010 and 2015 surveys. Overall, the prevalence of obesity increased by 6.1 percentage points (from 15.2% to 21.3%) between 2005 and 2015 (men from 10.4% to 15.7%; women from 18.2% to 25.7%). Among Afro-Colombians, obesity rose 6.6 percentage points (from 19.4% to 26.0%), again more so in women than in men (2015: 35.2% versus 17.8%). Among indigenous people, the proportion increased by 5.3 percentage points (from 13.5% to 18.8%), with women reporting highest rates (2015: 23.7% against 12.6% in men). Age- and cohort-specific results also indicate that recent adult cohorts are experiencing sharp increases in BMI, for example, while 25-29-year-old males born in 1975-1979 had a BMI of 24.2 kg/m², among 40-44-year-olds of the same cohort, this equalled 26.8 kg/m². In the case of women, these age differences in BMI among the same cohort are even greater (24.4 and 28.0 kg/m²). In summary, the results of this study indicate that Colombia is still in the early stages of the obesity transition, urging the need to monitor obesity trends in Colombia from both an age and cohort perspective. To achieve this, longitudinal surveys or repeated cross-sectional surveys like the ENSIN could be utilised.

Vaccines for COVID-19 began to be available in Africa from mid-2021. This paper reports on local reactions to the possibility of vaccination in one West African country, Sierra Leone. We show that the history of institutionalisation of vaccine is highly relevant to understanding these reactions. Given lack of testing for the disease, medical authorities could not be sure whether there was a hidden epidemic. In addition, many people associate vaccination with care of children under 5 years, and not adults, and an emphasis on vaccinating the old at first seemed strange and worrying. This paper examines evidence from ethnographic studies in two rural areas selected for varying exposure to Ebola Virus Disease (EVD), supplemented by some interviews in two provincial urban centres, Bo and Kenema. We describe local ideas about vaccination (maklet) and body marking with leaf medicine (tεwi). We asked about attitudes to the idea of COVID-19 vaccination both before and after vaccines were available. A number of reasons were given for scepticism and hesitation. These included lack of experience with vaccines for adults and lack of experience of COVID-19 as a severe disease. Medical evidence suggests the vaccination protects against serious illness, but local people had their own views about control of infection, based both recent experience (notably EVD) and the history and institutionalisation of vaccination and public health measures in Sierra Leone more broadly.

While social determinants of health have been perennially linked to child survival in resource-limited countries, the precise and tested pathways to effect are not clearly understood. The objective of this study was therefore to identify the critical pathways as posited a priori in a model through which social factors (at maternal, household, and community levels) determine neonatal, infant, and under-five mortalities in Nigeria. Using a novel analytic approach (hierarchical path modelling for predicting accelerated failure time) to estimate (in)direct and total effects of social determinants of child survival, we analysed 30,960 live births (weighted data for representativeness), obtained from the 2016/2017 Nigeria Multiple Indicator Cluster Survey. There were three outcome variables: time until occurrence of neonatal, infant, and under-five mortalities. The independent variables were layered factors related to child, maternal, household and community. Geographical region, rurality of residence, infrastructural development, maternal education, contraceptive use, marital status, and maternal age at birth were found to operate more indirectly on neonatal, infant, and under-five survival. Child survival is due to direct effects of child’s sex (female), gestational type (singleton), birth spacing (children whose mothers delivered at least two years apart), and maternal age at delivery (20–34 years). According to the path coefficients, the indirect effects of geographical regions are the most influential determinants of child survival, accounting for 30% (neonatal), 37.1% (infant) and 39.9% (under-five) of the total effects. This study offers comprehensive set of factors, and linked pathways, at the maternal, household, and community levels that are associated with child survival in Nigeria. To accelerate progress towards Sustainable Development Goal targets for child survival and reduce geographical inequities, stakeholders should implement more impactful policies that promote maternal education, contraceptive use and improve living conditions of women (especially in rural areas of northern Nigeria). Future research should focus on identifying the most effective interventions for addressing these social determinants of child survival in Nigeria.

The state of pregnancy and child birth is a stretch of intense vulnerability and incurs reproductive cost, which is governed within a specific socio-ecological context. We asked in our research whether the obstetric morbidities at three stages: antepartum, intrapartum and postpartum, and their concomitants differed significantly between sedente and migrant populations. 403 Oraon indigenous women [203 sedente and 200 migrants] living in Eastern India were selected. Data on socio-demographic, reproductive, maternal health care services and obstetric morbidities were collected using semi structured schedules. We applied Categorical Principal Component Analysis (CATPCA) on the first three variables; PC1 and PC4 were loaded with "socio-demographic and maternal health care services" and PC2 and PC3 loaded with "socio-demographic and reproductive" variables. We applied Poisson regression to examine the determinants of obstetric morbidities. Bivariate analyses showed significant (p ≤ 0.05) sedente-migrant differences in variables related to socio-demographic, reproductive, maternal health care and obstetric morbidities. Poisson regression showed migrants were more likely (p ≤ 0.001) to experience ante and intrapartum morbidities than the sedentes, after controlling the confounders. PC1, PC2 and PC3 could significantly (p ≤ 0.05) predict ante and intrapartum morbidities. For postpartum morbidities, barring the variables related to availing of maternal health care services at the time of child delivery and post delivery, neither migration status nor any of the PCs was a significant predictor. For example, participants who delivered their child in health institutions and had episiotomy and/or caesarean delivery (p ≤ 0.01); and those who availed first PNC within the 24 hours of delivery, stayed under medical supervision after delivery for more than 48 hours and received higher coverage of PNCs were more and less likely respectively (p ≤ 0.05) to have experienced postpartum morbidities. We conclude that the maternal obstetric morbidities and their concomitants differed between sedente and migrant Oraon populations owing to their living in differential socio-ecological contexts.

The study investigates the statistical relationship between male circumcision and HIV prevalence in Africa, in the context of the Voluntary Medical Male Circumcision (VMMC) campaigns in place since 2008. Data from the Population-based HIV Impact Assessment (PHIA) surveys conducted in African countries in 2017-2018 were utilized. Six countries with high HIV prevalence, low traditional circumcision and large VMMC programs were selected: Eswatini, Lesotho, Malawi, Namibia, Zambia, Zimbabwe. The statistical analysis investigated the relative risk (RR) of HIV prevalence by circumcision status (circumcised vs intact) among men age 20-59, and the age-incidence of HIV in the two groups among men age 20-49, defined as the linear-logistic slope of the relationship between prevalence and age. Results show that the standardized RR was not different from 1 at older ages (50-59): RR = 0.923, 95% CI = 0.769-1.108, P = 0.390. Furthermore, the age-incidence was at least as high or higher among the circumcised groups than among the intact groups. The standardized RR was lower than 1 at younger ages, and this could be explained by selection biases. HIV prevalence at age 40-59 (27.3%) was also the same in the four groups of circumcision status (intact, traditional, medical, unknown). Results matched earlier observations made in South Africa that circumcised and intact men had similar levels of HIV infection. The study questions the current strategy of large scale VMMC campaigns to control the HIV epidemic. These campaigns also raise a number of ethical issues.
