Food insecurity and men's perpetration of partner violence in a longitudinal cohort in South Africa

BACKGROUND

Although food insecurity has been associated with intimate partner violence (IPV), few studies examine it longitudinally or among male perpetrators.

METHODS

We used secondary data from a trial that followed 2479 men in a peri-urban settlement in South Africa (February 2016-August 2018). Men self-completed questionnaires at baseline (T0), 12 months (T1) and 24 months (T2) on food security, household type, relationship status, childhood abuse exposure, alcohol use, and perpetration of physical and/or sexual IPV. Cross-lagged dynamic panel modelling examines the strength and direction of associations over time.

RESULTS

At baseline, rates of IPV perpetration (52.0%) and food insecurity (65.5%) were high. Food insecure men had significantly higher odds of IPV perpetration at T0, T1 and T2 (ORs of 1.9, 1.4 and 1.4, respectively). In longitudinal models, food insecurity predicted men's IPV perpetration 1 year later. The model had excellent fit after controlling for housing, relationship status, age, childhood abuse and potential effect of IPV on later food insecurity (standardised coefficient=0.09, p=0.031. root mean squared error of approximation=0.016, comparative fit index=0.994). IPV perpetration did not predict later food security (p=0.276).

CONCLUSION

Food insecurity had an independent, longitudinal association with men's IPV perpetration in a peri-urban South African settlement. These findings suggest food security could be a modifiable risk factor of partner violence.

Food Insecurity and Intimate Partner Violence Among HIV-Positive Individuals in Rural Kenya

INTRODUCTION

Intimate partner violence and food insecurity are both structural drivers of HIV acquisition, care, and treatment, but little is known about how the 2 conditions intersect in the lives of those already living with HIV.

METHODS

This study examined cross-sectional baseline data (collected in January 2016-December 2017) from an ongoing trial in southwestern Kenya. Trained interviewers asked enrolled participants living with HIV aged 18-60 years about household food insecurity (using the Household Food Insecurity Access Scale), intimate partner violence (using an adapted WHO multicountry study instrument), and sociodemographics. Negative binomial regression was used to examine the association between food insecurity and partner violence victimization (among women) or perpetration (among men). Secondary data were analyzed in August 2019-March 2020.

RESULTS

Of 720 participants, more than half of women reported experiencing intimate partner violence (57.6%) and most men reported perpetrating it (58.4%). Participants reporting any partner violence had higher Household Food Insecurity Access Scale scores (21.8) compared with those reporting no violence (21.3, p=0.02). Each categorical change in food insecurity (mild, moderate, severe) was associated with a 41% increased risk of an additional partner violence episode. In models controlling for relationship status, wealth, season of interview (lean versus not lean), and baseline physical health, each 1-point increase in food insecurity was associated with a 6% higher risk of violence victimization among women and 4% greater risk of men perpetrating partner violence.

CONCLUSIONS

This study highlights the interconnected nature of intimate partner violence and food insecurity among women and men living with HIV. This relationship suggests that enhancing food security may be a useful intervention strategy to prevent intimate partner violence and improve HIV-related health outcomes.

Factors influencing the length of hospital stay of patients with anorexia nervosa - results of a prospective multi-center study

BACKGROUND

The length of stay (LOS) strongly influences anorexia nervosa (AN) inpatient weight outcomes. Hence, understanding the predictors of LOS is highly relevant. However, the existing evidence is inconsistent and to draw conclusions, additional evidence is required.

METHODS

We conducted a prospective, multi-center study including adult female inpatients with AN. Using stepwise linear regression, the following demographic and clinical variables were examined as potential predictors for LOS: admission BMI, AN-subtype, age, age of onset, living situation, partnership status, education, previous hospitalization, self-rated depression, anxiety and somatic symptoms (PHQ-9, PHQ-15, GAD-7), self-rated therapy motivation (FEVER) and eating disorder psychopathology (EDI-2 subscale scores).

RESULTS

The average LOS of the sample (n = 176) was 11.8 weeks (SD = 5.2). Longer LOS was associated with lower admission BMI (ß = -1.66; p < .001), purging AN-subtype (ß = 1.91; p = .013) and higher EDI-2 asceticism (ß = 0.12; p = .030). Furthermore, differences between treatment sites were evident.

CONCLUSIONS

BMI at admission and AN-subtype are routinely assessed variables, which are robust and clinically meaningful predictors of LOS. Health care policies might consider these variables. In light of the differences between treatment sites future research on geographical variations in mental health care seems recommended.

Using daily monitoring of psychiatric symptoms to evaluate hospital length of stay

BACKGROUND

Routine symptom monitoring and feedback improves out-patient outcomes, but the feasibility of its use to inform decisions about discharge from in-patient care has not been explored.

AIMS

To examine the potential value to clinical decision-making of monitoring symptoms during psychiatric in-patient hospitalisation.

METHOD

A total of 1102 in-patients in a private psychiatric hospital, primarily with affective and neurotic disorders, rated daily distress levels throughout their hospital stay. The trajectories of patients who had, and had not, met a criterion of clinically significant improvement were examined.

RESULTS

Two-thirds of patients (n=604) met the clinically significant improvement criterion at discharge, and three-quarters (n=867) met the criterion earlier during their hospital stay. After meeting the criterion, the majority (73.2%) showed stable symptoms across the remainder of their hospital stay, and both classes showed substantially lower symptoms than at admission.

CONCLUSIONS

Monitoring of progress towards this criterion provides additional information regarding significant treatment response that could inform clinical decisions around discharge readiness.
