Lifetime Spousal Violence Victimization and Perpetration, Physical Illness, and Health Risk Behaviours among Women in India

Food-based domestic violence and anemia among women in sexual unions in Nigeria: the effect of urbanization

In 2019, 1.74 billion people worldwide had anemia. In Nigeria, women of reproductive age are the most affected. Domestic violence affects the anemia prevalence, but few studies have examined the influence of urbanization on women in heterosexual unions (currently married, and cohabiting between). Using the social determinants of health framework, we argue that food-based violence and anemia vary among women residing in rural and urban areas. We used the Chi-square test and logistic regression to analyze the 2018 Nigeria Demographic and Health Survey records (n = 10,499). The study showed that anemia occurs more among women in rural (66%) than in urban (34%) areas. In rural areas, anemia was 29% higher among women who approved food-based domestic violence (OR: 1.29, CI 1.15-1.57) than those who did not. In urban areas, food-based domestic violence was not significantly associated with anemia. This study emphasizes the urgent need for culturally sensitive maternal health interventions aimed at re-orienting individuals and families on violence in rural areas.

Association between domestic violence and unintended, terminated pregnancy and complications during pregnancy among Indian women: Findings from nationally representative survey

Background

Women experiencing domestic violence might have restrictions in the pregnancy-related decision-making and care-seeking process leading to adverse pregnancy outcomes. We explored the association between domestic violence and undesirable pregnancy events.

Methods

63,796 women aged 18-49 years covered under the domestic violence module of National Family Health Survey-5, 2019-21. Stratification and clustering in the complex sampling design of the survey were accounted in analysis. Using Poisson regression, prevalence ratio (PR) was reported to provide association of domestic violence with undesirable pregnancy events.

Results

Prevalence of undesirable pregnancy events was 25.0% (95%CI: 24.4%-25.7%) amongst women aged 18-49 years. Prevalence of unintended, terminated pregnancy and complications during pregnancy was 3.2%, 5.1% and 20.9%, respectively. Women aged ≥35 years, educated, unemployed, primi or multi parity, intimate partner/husband being uneducated, facing problem with access to healthcare, belonging to large number of household members (≥4) and poorest or poorer quintile had significantly higher chance of having undesirable pregnancy events. Sexual violence (aPR: 1.11, p = 0.02) had higher chance of having undesirable pregnancy events.

Conclusion

One-fourth of reproductive-age group women had undesirable pregnancy events. Sexual violence was significantly associated with these events. Effective policy should protect women from domestic violence to promote maternal well-being.

Associations of history of intimate partner violence with mental ill-health and lifestyle factors in middle-aged and older men and women in South Africa

OBJECTIVES

The aim of this study was to assess the association between history of intimate partner violence (IPV) exposure and mental and lifestyle factors among middle-aged and older men and women in rural South Africa.

METHODS

The analysis utilized data from wave 3 of the longitudinal Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) (n = 3,707, median age 66 years, range 46-118 years). History of IPV was assessed with five questions on physical, sexual, psychological, and economic IPV. Logistic regression was used to assess the association between history of IPV exposure and mental and lifestyle factors.

RESULTS

Among men 7.8% and among women 10.9% reported a history of IPV. In terms of mental health outcomes, in the final adjusted model, among men, exposure to 1 and/or 2-4 types of IPV were associated with depressive symptoms, insomnia symptoms, PTSD, and loneliness, while among women, exposure to 1 and/or 2-4 types of IPV was associated with insomnia symptoms and PTSD. In terms of lifestyle outcomes, in the final adjusted model, among men, 2-4 types of IPV were associated current tobacco use, current heavy alcohol use, inadequate fruit intake, and food insecurity, and among women, 1 and/or 2-4 types of IPV were associated with soft drink intake, and food insecurity.

CONCLUSION

We found that lifetime exposure to IPV was associated with several mental and lifestyle factors in middle-aged and older men and women. Enhanced screening and treatment of IPV may reduce poor mental and health risk behavior among this aging male and female population in South Africa.

Adverse Events during Adulthood, Child Maltreatment, and Asthma among British Adults in the UK Biobank

Rationale: Intimate partner violence and child maltreatment have been separately associated with asthma in adults. No study has concurrently examined of adulthood adverse events (including, but not limited to, intimate partner violence) and child maltreatment on asthma in adults. Objectives: To concurrently examine of adulthood adverse events and child maltreatment on asthma in adults. Methods: This was a cross-sectional study of adulthood adverse events and child maltreatment on current asthma in 87,891 adults 40-69 years old who participated in the UK Biobank. Adulthood adverse events were assessed using questions adapted from a national crime survey. Child maltreatment was ascertained using the Childhood Trauma Screener questionnaire. Current asthma was defined as physician-diagnosed asthma and current wheeze and was further classified as noneosinophilic or eosinophilic according to eosinophil count (<300 vs. ⩾300 cells per microliter). Results: In a multivariable analysis, participants who reported two or more types of adulthood adverse events had 1.19-1.45 times significantly higher odds of asthma than those who did not, whereas participants who reported two or more types of child maltreatment had 1.25-1.59 significantly higher odds of asthma than those who reported no child maltreatment. After stratification by sex, similar results were obtained for child maltreatment in women and men, whereas adulthood adverse events were only significantly associated with asthma in women. Similar findings were observed in analyses that were restricted to never-smokers and former smokers with <10 pack-years of smoking and in analyses of noneosinophilic and eosinophilic asthma. Conclusions: In a cohort of British adults, child maltreatment was associated with current asthma in men and women, whereas adulthood adverse events were associated with current asthma in women only. This was independent of cigarette smoking or eosinophil count.

Association between intimate partner violence and nutritional status among Indian women: a latent class analysis approach

BACKGROUND

Intimate partner violence (IPV) is an unabating public health issue that has numerous negative repercussions for women's health. Its detrimental impact on women's nutritional outcomes has been documented in a few studies from low- and middle-income countries; however, there is a lack of granular understanding in terms of the typology of IPV experiences and their association with nutritional outcomes. This study explores the distinct classes of IPV experience among women in India and examines how these classes are associated with their nutritional outcomes.

METHODS

Using data of 60,622 ever-married women aged 15-49 years from the 2019-21 National Family Health Survey (NFHS-5), latent class analysis (LCA) was performed to identify distinct groups of women based on their IPV experiences. BMI was used to assess women's nutritional status, and it was classified as: <18.5 kg/m2 (underweight), 18.5-24.9 kg/m2 (normal) and ≥ 25.0 kg/m2 (overweight). Further, multinomial logistic regression analyses were used to estimate the odds of being underweight or overweight by latent classes of IPV experiences.

RESULTS

LCA model identified four distinct IPV experience groups of women: Low Physical and Low Sexual IPV (LPLS-IPV) class (72%); High Physical and Low Sexual IPV (HPLS-IPV) (12.5%); High Sexual and Low Physical IPV (HSLP-IPV) (12%); and High Physical and High Sexual (HPHS-IPV) class (3.5%). The likelihood of being underweight was higher among women in the HPHS-IPV class (aOR: 1.24, 95% CI: 1.08-1.44), followed by those in the HPLS-IPV class (aOR: 1.11, 95% CI: 1.04-1.20).

CONCLUSION

The latent class groups found that high physical IPV experiences were associated with women's nutritional outcomes. The experiences of women having both high physical and sexual violence affect women's nutritional outcomes to a greater extent and they are more likely to be undernourished.

The association between access to key household resources and violence against women

We provide the first comprehensive analysis of the association between two key household resources (drinking water and toilet access) and both non-partner violence (NPV) and intimate partner violence (IPV) experienced by women. We use data from a nationally representative household survey for India obtained from the latest (fourth) round of the National Family Health Survey conducted in 2015-16. We employ logistic regression method and also use inverse-probability-weighted regression adjustment to control for selection bias. We find that NPV decreases with access to drinking water, while IPV decreases with provision of toilets. These results are found to be robust to an alternative method viz. propensity score matching and selection on unobservables using the Rosenbaum bounds approach.

Intimate Partner Violence, Mental Health Symptoms, and Modifiable Health Factors in Women During the COVID-19 Pandemic in the US

Importance

During the COVID-19 pandemic, the prevalence and severity of intimate partner violence (IPV) increased. Associations between IPV and mental health symptoms and modifiable health factors early in the pandemic have yet to be explored.

Objective

To prospectively investigate the association of IPV with greater risk of mental health symptoms and adverse health factors during the COVID-19 pandemic in 3 cohorts of female participants.

Design, Setting, and Participants

This cohort study used observational data from 3 prospective, population-based, longitudinal cohorts in the US: the Nurses' Health Study II, Growing Up Today Study, and Nurses' Health Study 3. Data analyzed included baseline and follow-up survey responses about IPV experiences early in the pandemic (March-September 2020); mental health domains of depression, anxiety, and posttraumatic stress symptoms (PTSS); and modifiable health factors (May 2020-October 2021). Female participants (both health care professionals and non-health care workers) aged 21 to 60 years from the 3 cohorts were included in the full analytic sample.

Exposures

Experience of IPV measured by the Relationship Assessment Tool and fear of partner.

Main Outcomes and Measures

Mental health symptoms, including depression, anxiety, and PTSS, and modifiable health factors, including sleep duration, sleep quality, physical activity, alcohol use, and use of alcohol or other substances to cope with stress.

Results

The full analytic sample included 13 597 female participants with a mean (SD) age of 44 (10.6) years. Accounting for sociodemographic factors and prepandemic mental health symptoms and correcting for multiple testing, experiencing IPV was associated with higher endorsement of depression (odds ratio [OR], 1.44; 95% CI, 1.38-1.50), anxiety (OR, 1.31; 95% CI, 1.26-1.36), and PTSS (OR, 1.22; 95% CI, 1.15-1.29) in random-effects meta-analyses across the 3 cohorts. The IPV experience was also associated with poorer sleep quality (OR, 1.21; 95% CI, 1.16-1.26), shorter sleep duration (OR, 1.13; 95% CI, 1.08-1.19), increased use of alcohol (OR, 1.10; 95% CI, 1.06-1.14), and use of alcohol or other substances to cope with stress (OR, 1.13; 95% CI, 1.08-1.18) across all cohorts as well as decreased physical activity (OR, 1.17; 95% CI, 1.09-1.26) in the Nurses' Health Study II only.

Conclusions and Relevance

Results of the study showed that IPV experiences at the start of the pandemic were associated with worse mental health symptoms and modifiable health factors for female participants younger than 60 years. Screening and interventions for IPV and related health factors are needed to prevent severe, long-term health consequences.

Understanding the Impact of Intimate Partner Violence Type and Timing on Pre-exposure Prophylaxis Knowledge, Acceptability, Sexual Behavior, and Gender Roles Among Women of Color

Knowledge and acceptability are key factors for pre-exposure prophylaxis (PrEP) use among women with a history of intimate partner violence (IPV) and research suggests that different types of IPV affect PrEP uptake differently. Few studies have examined whether the type (i.e., physical, sexual, and psychological) and timing (i.e., lifetime, past year) of IPV experiences are related to PrEP knowledge and acceptability, or whether gender roles and sexual risk behaviors affect PrEP use. We aimed to examine the associations between lifetime and past-year physical, sexual, and psychological IPV experiences on PrEP-related outcomes (i.e., knowledge, acceptability, sexual behavior if on PrEP) and the association between gender roles and PrEP-related outcomes. A total of 186 women of color at risk for HIV participated in this study, of whom 54% had ever experienced partner violence. Results showed that lifetime psychological (OR 3.0, 95% CI 1.1-9.4) and lifetime physical IPV (OR 5.5, 95% CI 1.2-18.9) were significantly associated with increased PrEP knowledge. lifetime psychological (OR 6.3, 95% CI 1.0-13.6) and lifetime physical IPV (OR 4.3, 95% CI 4.3-11.5) were significantly associated with increased sexual behavior if on PrEP. Past year physical IPV was significantly associated with interest in using PrEP (OR 1.9, 95% CI 1.7-4.3) and with sexual behavior if on PrEP (OR 4.0, 95% CI 1.1-13.1). Being subordinate to others was also significantly associated with interest in using PrEP (OR 1.5, 95% CI 1.2-2.4) Self-silencing was significantly associated with increased sexual behavior if on PrEP (OR 1.2, 95% CI 1.0-1.5). Gender norms and IPV type and timing can influence whether a person is interested in PrEP use. Both lifetime and past-year IPV experiences need to be examined in the context of gender norms when prescribing PrEP to encourage uptake and continuation among vulnerable women at risk for HIV.

Determinants of domestic violence among women of reproductive age (15-49 years) in Quetta, Balochistan-a mixed-method protocol

BACKGROUND

Worldwide, domestic violence (DV) is a cause of death and disability among women aged 15-49 years. In Pakistan, DV appears in different forms, and only 3.2% of women report any DV. There are various factors associated with DV against women. The data are sparse for the Balochistan province due to the under-reporting and scattered population. This research study aims to determine the factors associated with DV and the types of violence among women of reproductive age. Also, to understand the perspective of community leaders and healthcare workers (HCWs) for developing interventions for DV prevention against women of reproductive age in Quetta Balochistan.

METHODS AND ANALYSIS

A sequential explanatory mixed-method (quantitative study followed by qualitative) study design will be used to fulfil the study's objectives. Women of reproductive age (15-49 years), both married and unmarried, local residents, community leaders and community HCWs of Quetta Balochistan, will be made part of the study. A structured questionnaire will be used as the quantitative tool. Focus group discussions will be conducted using a semistructured guide for the qualitative data collection. The multivariable logistic regression analysis will be performed for the quantitative part. P value ≤0.05 will be considered significant. In the qualitative part, data will be transcribed, and recurrent themes/subthemes will be developed to understand the perspective and opinion regarding DV prevention.

ETHICS AND DISSEMINATION

Ethical Approval was taken from Aga Khan University, Karachi, Pakistan. Informed written consent will be obtained from all participants. The article will be published after data collection and analysis in the journal to disseminate the results.

Clinical and psychosocial factors associated with domestic violence among men and women in Kandy, Sri Lanka

Domestic violence (DV) is a violation of human rights with adverse intergenerational consequences on physical and mental health. Clinical and psychosocial correlates of DV have been documented internationally, but evidence from South Asia is limited, especially among men. This is a nested cross-sectional study of the control population (N = 856) of a large case-control study in Kandy, Sri Lanka. Multivariable logistic regression models were conducted to estimate the association between clinical and psychosocial factors and experience of DV. Overall associations were examined and stratified by sex and type of abuse. Overall, 19% (95% CI 16%-21%) of the sample reported DV of any form in past year, with a similar prevalence being reported in both men (18% 95% CI 14%-22%) and women (19% 95% CI 15%-23%). Depression symptoms (adjusted OR [AOR] 3.28 95% CI 2.13-5.05), suicidal ideation (AOR 6.19 95% CI 3.67-10.45), prior diagnosis of a mental illness (AOR 3.62 95% CI 1.61-8.14), and previous self-harm (AOR 6.99 95% CI 3.65-13.38) were strongly associated with DV, as were indicators of perceived poor social support (AOR range 2.48-14.18). The presence of in-laws (AOR 2.16 95% CI 1.34-3.48), having three or more children (AOR 2.15 95% CI 1.05-4.41) and being divorced/separated/widowed were also strongly associated with DV (AOR 2.89 95% CI 1.14-7.36). There was no statistical evidence that any associations differed by sex. A multi-sectoral approach is needed to address DV in this context. Enhanced coordination between DV support services and mental health services may be beneficial. Further research and support for men as well as women is needed.

Intimate partner violence and asthma in pediatric and adult populations

OBJECTIVE

To evaluate the relationship between intimate partner violence (IPV) and adult and childhood asthma outcomes.

DATA SOURCES

We conducted a systematic literature review using 4 databases (PubMed, Ovid MEDLINE, Ovid Embase, and Ovid PsycINFO) with asthma and IPV-associated terms.

STUDY SELECTIONS

We included published studies, available in English, to October 2021, which included IPV as an exposure and asthma as an outcome. Both adult and pediatric populations were included in the following settings: community, health care, and home.

RESULTS

There were 37 articles identified. There was evidence among multiple studies to support increased prevalence of asthma in adults exposed to IPV and prevalence and incidence in children with parental IPV exposure. There were fewer studies evaluating IPV exposure and adult asthma morbidity, but they found statistically significant associations between IPV and increased rate of asthma exacerbations and worsened asthma control. There was sparse evidence evaluating a relationship between IPV and adult asthma mortality. There were no studies identified evaluating IPV and childhood asthma morbidity or mortality.

CONCLUSION

The association between IPV and increased asthma prevalence, incidence, and worsened morbidity merits recognition and further investigation into potential mechanisms. Health care providers can implement practical strategies to help mitigate the negative effects of IPV on health and asthma. These include addressing potential impactful biopsychosocial factors and comorbidities, implementing routine screening and referrals, and partnering with community advocacy organizations. Given their positions of respect and power in society, health care providers can have lasting impacts on the lives of pediatric and adult patients affected by IPV.

Sexual Violence and Risk of Hypertension in Women in the Nurses' Health Study II: A 7-Year Prospective Analysis

Background Hypertension is a prevalent condition in women and an important modifiable risk factor for cardiovascular disease. Despite women's experiences of sexual violence being common, no prospective studies have examined lifetime sexual assault and workplace sexual harassment in relationship to hypertension in large civilian samples with extended follow-up. Here, we examined whether these experiences were prospectively associated with greater risk of developing hypertension over 7 years. Methods and Results Data are from a substudy of the Nurses' Health Study II and include women free of hypertension at the time of sexual assault and workplace sexual harassment assessment in 2008 (n=33 127). Hypertension was defined as self-reported doctor diagnosis or initiating antihypertensive medication use, assessed biennially through 2015. We performed Cox proportional hazards regression models to predict time to developing hypertension associated with sexual violence exposure, adjusting for relevant covariates. Over follow-up, 7096 women developed hypertension. Sexual assault and workplace sexual harassment were prevalent (23% and 12%, respectively; 6% of women experienced both). Compared with women with no exposure, women who experienced both sexual assault and workplace sexual harassment had the highest risk of developing hypertension (hazard ratio [HR], 1.21; 95% CI, 1.09-1.35), followed by women who experienced workplace sexual harassment (HR, 1.15; 95% CI, 1.05-1.25) and then by women who experienced sexual assault (HR, 1.11; 95% CI, 1.03-1.19), after adjusting for relevant covariates. Conclusions Sexual assault and workplace sexual harassment are prospectively associated with greater risk of hypertension. Reducing such violence is important in its own right and may also improve women's cardiovascular health.

Domestic violence and its associated factors among married women in urban Chennai: A cross-sectional study

Context:

Domestic violence against married women is a sensitive issue, which is prevalent in many societies and countries across the world. One in every three women experiences it in some form across the world, with prevalence ranging from 10 to 69% across various settings.

Aims:

To find the extent of domestic violence in Urban Chennai, Tamil Nadu and to find the factors associated with it.

Settings and Design:

A cross-sectional study is done in the urban field practice area of Saveetha medical college and hospital, Thirumazhisai area in Chennai, Tamil Nadu.

Methods and Material:

The participants who matched our inclusion criteria and who were residing in the area were included in the study. Convenient sampling method was used to collect data. A semi-structured questionnaire was used.

Statistical Analysis Used:

Data was analyzed by calculating Percentages and Proportions and was presented in suitable tabular. Statistical test like Odds ratio and Chi-Square was used for finding the factors associated with the study variables. Bivariate and multivariate analysis was conducted to identify factors associated with domestic violence.

Results:

The overall prevalence of domestic violence was 38.2%, with physical, sexual, psychological, and emotional violence comprising of 28.7%, 9.1%, 12.6%, and 15.4%, respectively. Multivariate analysis found that the involvement of women in decision-making at their home, alcohol abuse among husbands, religion and husband’s education (P < 0.0001) were significantly associated with domestic violence.

Conclusions:

The prevalence of domestic violence recorded was high. Moral support and necessary measures needs to be taken to empower women against it.

Intimate partner violence, circulating glucose, and non-communicable Disease: Adding insult to injury?

Analyzing data from the 2015-2016 Indian Demographic and Health Survey (N = 41,768), we investigate how women's circulating glucose varies with the severity of intimate partner violence (IPV) they have experienced in the last year and how their likelihoods of corresponding noncommunicable diseases vary with IPV severity in their lifetime. Consistent with a physiological stress response, women who have recently experienced severe IPV exhibit higher glucose levels and are more likely to have extremely high levels-forewarning of disease development-than women who have not experienced IPV. Correspondingly, women who have ever experienced severe IPV in their lifetime have 33%-200% higher probabilities of diabetes, heart disease, thyroid disorders, and cancer and are 70% more likely to have any of these diseases and 175% more likely to have multiple than women who have experienced none.

Qualidade de vida de mulheres e homens idosos em situação de violência por parceiro íntimo

Resumo Este artigo buscou investigar a associação entre a violência por parceiro íntimo (VPI) e os níveis de qualidade de vida (QV) e seus domínios (controle e autonomia; realização pessoal e prazer), em pessoas idosas. Realizou-se estudo transversal de base populacional da segunda onda (2013/2014) do Estudo EpiFloripa, com pessoas idosas (n=649), residentes em Florianópolis, SC, Sul do Brasil. As médias de QV e seus domínios foram descritas segundo as variáveis de ajuste (idade, renda, deficit cognitivo, sintomas depressivos e dependência de atividades de vida diária), estratificadas por sexo. Analisou-se a associação entre VPI e QV por meio de regressão linear múltipla, com significância estatística de 5%. Os escores médios de QV, bem como realização pessoal e prazer foram semelhantes entre os sexos, enquanto o controle e autonomia das mulheres foram significativamente inferiores em comparação aos homens (p=0,04). Observou- se menores escores de QV nas mulheres expostas à situação de violência, nas três direcionalidades analisadas: perpetrada (-3,15; IC95%: -4,84; -1,45), bidirecional (-2,59; IC95%: -4,10; -1,09) e sofrida (-1,62; IC95%: -3,06; -0,17) e as mais prejudicadas foram aquelas que cometeram agressões. O controle e autonomia foi afetado para as perpetradoras e envolvidas na violência bidirecional, enquanto menores escores de realização pessoal e prazer foram verificados entre as idosas, em quaisquer situações de violência. Os homens não tiveram sua QV prejudicada por estarem em situação de VPI, tanto vítimas como perpetradores dessa violência. Concluiu-se que a VPI possui impacto assimétrico sobre a QV de pessoas idosas em relação ao sexo, prejudicando com maior intensidade as mulheres.

Understanding Domestic Violence in India During COVID-19: a Routine Activity Approach

Domestic violence, a prevalent problem in India, saw an increase during the lockdown imposed to contain the spread of COVID-19. This article explores the factors associated with an increase in domestic violence incidents during COVID-19 by applying routine activity theory (RAT) framework. Data were drawn from the incidents of domestic violence reported in newspapers. Data was analyzed using content analysis and three major themes, i.e., three principle components of RAT-motivated offender, suitable target, and absence of capable guardian-were drawn. Findings reveal that sources of motivation in domestic violence perpetrators during the lockdown were alcohol and unemployment. The symbolic value that perpetrators associated with women, lower inertia, visibility, and accessibility to the perpetrators made women suitable targets of domestic violence. Lastly, shortage of police force and travel restrictions on formal and informal sources resulted in the absence of capable guardians. We conclude that changes in the routine activities of people during the COVID-19 lockdown provided more opportunities to the perpetrators of domestic violence.

Association of Maternal Body Mass Index With Risk of Infant Mortality: A Dose-Response Meta-Analysis

Objective: This study presumed that a high or low body mass index (BMI) might increase the risk of infant mortality. Therefore, a meta-analysis was performed to systematically assess the association between maternal BMI and the risk of infant mortality. Methods: The electronic databases, including Pubmed, Embase database, and Cochrane Library, were systemically searched by two investigators from inception to November 26th, 2020, with no language restriction. In parallel, a dose-response was assessed. Results: Finally, 22 cohort studies involving 13,532,293 participants were included into this paper, which showed that compared with normal BMI, maternal overweight significantly increased the risks of infant mortality [risk ratio (RR), 1.16; 95% confidence interval (CI), 1.13-1.19], neonatal mortality (RR, 1.23; 95% CI, 1.08-1.39), early neonatal mortality (RR, 1.55; 95% CI, 1.26-1.92) and post-neonatal mortality (RR, 1.18; 95% CI, 1.07-1.29). Similarly, maternal obesity significantly increased the risk of infant mortality (RR, 1.55; 95% CI, 1.41-1.70), neonatal mortality (RR, 1.55; 95% CI, 1.28-1.67), early neonatal mortality (RR, 1.37; 95% CI, 1.13-1.67), and post-neonatal mortality (RR, 1.30; 95% CI, 1.03-1.65), whereas maternal underweight potentially decreased the risk of infant mortality (RR, 0.93; 95% CI, 0.88-0.98). In the dose-response analysis, the risk of infant mortality significantly increased when the maternal BMI was >25 kg/m². Conclusions: Maternal overweight or obesity significantly increases the risks of infant mortality, neonatal mortality, early neonatal mortality, and post-neonatal mortality compared with normal BMI in a dose-dependent manner. Besides, maternal underweight will not increase the risk of infant mortality, neonatal mortality, early neonatal mortality, or postneonatal mortality; instead, it tends to decrease the risk of infant mortality. Early weight management may provide potential benefits to infants, and more large-scale prospective studies are needed to verify this finding in the future.

Associations of physical partner violence and sexual violence victimization on health risk behaviours and mental health among university students from 25 countries

BACKGROUND

The study aimed to investigate the associations between physical partner violence victimization (IPV) and/or sexual violence victimization and various health risk behaviours and mental health in university students in 25 countries.

METHODS

Using a cross-sectional study design, 18,335 university students with a median age of 20 years from 25 countries in Africa, the Americas and Asia, replied to self-reported measures of interpersonal violence, health compromising behaviours, mental health measures and protective factors.

RESULTS

In adjusted logistic regression analysis, physical IPV and/or sexual violence victimization was associated, among men and/or among women, with sexual risk behaviours (multiple sexual partners, alcohol use in the context of sex, diagnosed with HIV and pregnancy), violence related behaviour (in a physical fight and carrying a weapon), poor mental health (depression, loneliness, post-traumatic stress disorder, sleeping problem and short sleep), addictive behaviour (binge drinking, tobacco and drug use), and other health risk behaviour (skipping breakfast and frequent salt intake).

CONCLUSIONS

We found evidence that physical IPV and/or sexual violence victimization among female and/or male university students was associated with 4 of 5 sexual risk behaviours, 2 violence related behaviours, 5 of 5 poor mental health indicators, 3 of 3 addictive behaviours and 2 of 7 other health risk behaviours.

Public health impact of marital violence against women in India

The public health ramifications of marital violence are well documented and include injury, mental health concerns and physical health consequences for women and their offspring. Unfortunately, there remains social tolerance and even acceptance of these abuses against women, and health systems in India have done little to support victims despite their greater health risks. However, there are promising efforts and important advancements in India that could be built on for more effective prevention and support for women. Men and boys should be engaged in gender transformative interventions with male role models to alter men's attitudes of acceptability of and justification for marital violence and consequently their actual abusive behaviours. Given the strong demonstrated connection between men's risky and problem alcohol use and marital violence, alcohol interventions may also be beneficial. We must support women and girls vulnerable to marital violence, a group disproportionately affected by violence in their natal families as well, so they know that violence need not be part of their marriage relationship, and have skills on how to engage and communicate with or even leave their male partners to reduce their risk for violence. Formal services should be expanded for those in immediate danger and particularly for rural areas, where prevalence of marital violence is highest and supports are weakest. Finally, given the pervasiveness of attitudes accepting husbands' marital violence against women, and the fact that these have remained largely unchanged in India for a decade, large scale community and social change efforts are needed.

Optimal gestational weight gain for underweight pregnant women in Japan

We aimed to investigate the optimal range of gestational weight gain (GWG) for Japanese underweight (body mass index <18.5 kg/m²) women using the Japanese Birth Registry System. The study subjects included underweight women who were divided into groups according to the GWG recommendations of the Ministry of Health, Labour and Welfare (MHLW) (9–12 kg): <9.0 kg, group A; 9–12 kg, group B; and >12 kg, group C. The subjects were then classified according to the recommendations of the Institute of Medicine (IOM) (12.7–18.1 kg): <12.7 kg, group D; 12.7–18.1 kg, group E; and >18.1 kg, group F. In total, 148,135 cases were analysed. The frequencies of small for gestational age, preterm delivery, and caesarean delivery were as follows: 19.3%, 22.7%, and 28.5% for group A; 11.7%, 8.7%, and 22.8% for group B; 8.0%, 4.9%, and 21.5% for group C; 15.0%, 14.7%, and 25.2% for group D; 8.0%, 5.3%, and 21.5% for group E; and 7.0%, 5.5%, and 25.0% for group F, respectively. These results indicated that groups C and E had the best outcomes. Therefore, the IOM guidelines seem more appropriate than the MHLW guidelines. Therefore, the MHLW recommended GWG guidelines require revision.
