Background: Mortality among children with acute illness in low-income and middle-income settings remains unacceptably high and the importance of post-discharge mortality is increasingly recognised. We aimed to explore the epidemiology of deaths among young children with acute illness across sub-Saharan Africa and south Asia to inform the development of interventions and improved guidelines.
Methods: In this prospective cohort study, we enrolled children aged 2-23 months with acute illness, stratified by nutritional status defined by anthropometry (ie, no wasting, moderate wasting, or severe wasting or kwashiorkor), who were admitted to one of nine hospitals in six countries across sub-Saharan Africa and …

Background: Selenium (Se), an essential trace mineral, has been implicated in preterm birth (PTB). We aimed to determine the association of maternal Se concentrations during pregnancy with PTB risk and gestational duration in a large number of samples collected from diverse populations.
Methods: Gestational duration data and maternal plasma or serum samples of 9946 singleton live births were obtained from 17 geographically diverse study cohorts. Maternal Se concentrations were determined by inductively coupled plasma mass spectrometry analysis. The associations between maternal Se with PTB and gestational duration were analysed using logistic and linear regressions. The results were then combined using …

School of Nursing & Midwifery

Background: The COVID‑19 pandemic and associated public health measures have disrupted the lives of people around the world. It is already evident that the direct and indirect psychological and social effects of the COVID‑19 pandemic are insidious and affect the mental health of young children and adolescents now and will in the future. The aim and objectives of this knowledge-synthesis study were to identify the impact of the pandemic on children's and adolescent's mental health and to evaluate the effectiveness of different interventions employed during previous and the current pandemic to promote children's and adolescents' mental health.
Methodology: We conducted …

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape …


Development And Validation Of A Psychometric Scale To Assess Attitude Towards Safe Abortions In Pakistan, Xaher Gul, Junaid-Ur-Rehman Siddiqui, Miraal Mavalvala, Waqas Hameed, Muhammad Ishaque Jan 2021

Development And Validation Of A Psychometric Scale To Assess Attitude Towards Safe Abortions In Pakistan, Xaher Gul, Junaid-Ur-Rehman Siddiqui, Miraal Mavalvala, Waqas Hameed, Muhammad Ishaque

Community Health Sciences

Despite severe health and economic consequences that women face because of the negative attitude of healthcare providers towards safe abortion and post-abortion care (SA/PAC), no psychometric tool has yet been validated for assessing the attitude towards SA/PAC. Only a handful of studies have attempted to assess healthcare providers' attitude towards safe abortions in Pakistan. Therefore, this study aimed to develop and validate a psychometric scale to assess attitude towards safe abortions in Pakistan. The study collected data from 106 workers of an NGO that provides SA/PAC through an online and anonymous survey using the organisation's network. The study used factor …


Improving Pregnancy Outcomes In Low- And Middle-Income Countries, Robert L. Goldenberg, Elizabeth M. Mcclure, Sarah Saleem Jun 2018

Improving Pregnancy Outcomes In Low- And Middle-Income Countries, Robert L. Goldenberg, Elizabeth M. Mcclure, Sarah Saleem

Community Health Sciences

This paper reviews the very large discrepancies in pregnancy outcomes between high, low and middle-income countries and then presents the medical causes of maternal mortality, stillbirth and neonatal mortality in low-and middle-income countries. Next, we explore the medical interventions that were associated with the very rapid and very large declines in maternal, fetal and neonatal mortality rates in the last eight decades in high-income countries. The medical interventions likely to achieve similar declines in pregnancy-related mortality in low-income countries are considered. Finally, the quality of providers and the data to be collected necessary to achieve these reductions are discussed. It …


Inequities In Antenatal Care, And Individual And Environmental Determinants Of Utilization At National And Sub-National Level In Pakistan: A Multilevel Analysis, Ambreen Sahito, Zafar Fatmi Jan 2018

Inequities In Antenatal Care, And Individual And Environmental Determinants Of Utilization At National And Sub-National Level In Pakistan: A Multilevel Analysis, Ambreen Sahito, Zafar Fatmi

Community Health Sciences

Background: Nationally representative surveys are vital for gauging progress in health and planning health services. However, often marred with inadequate analysis to provide any guidance to health policy and planning. Most recent Pakistan Demographic and Health Survey (PDHS) 2012-2013 is an inclusive nationally representative investigation. Nonetheless, its published report offers limited evidence regarding antenatal care (ANC). Furthermore, after 18th constitutional amendment, policies are principally made at provincial level in Pakistan; therefore, it is imperative to have contextual evidence at sub-national level to feed programs and policies.
Methods: We analysed 7142 women with a recent birth, to assess the …

Community Health Sciences

Background: Maternal stature and body mass indices (BMI) of non-pregnant women (NPW) of child bearing age are relevant to maternal and offspring health. The objective was to compare anthropometric indices of NPW in four rural communities in low- to low-middle income countries (LMIC).
Methods: Anthropometry and maternal characteristics/household wealth questionnaires were obtained for NPW enrolled in the Women First Preconception Maternal Nutrition Trial. Body mass index (BMI, kg/m2) was calculated. Z-scores were determined using WHO reference data.
Results: A total of 7268 NPW participated in Equateur, DRC (n = 1741); Chimaltenango, Guatemala (n = 1695); North …


Unintended Pregnancies Among Married Women In Sindh Pakistan: Role Of Lady Health Workers, Sumera Aziz Ali, Unaib Rabbani Jan 2017

Unintended Pregnancies Among Married Women In Sindh Pakistan: Role Of Lady Health Workers, Sumera Aziz Ali, Unaib Rabbani

Community Health Sciences

Background: Unintended pregnancies, which pose substantial risks to both mothers and children, account for 24% of all pregnancies in Pakistan. Door to door visits and service provision by lady health workers (LHWs) may be related to the reduction of such pregnancies, particularly in rural areas. This study aimed to determine the association of knowledge about Lady Health Visitors (LHWs) and door to door visits by LHWs with unintended pregnancies among rural women.
Methods: We conducted a community-based, nested case-control study of 800 pregnant women, identified from the database of an active surveillance mechanism, which registers and follows all pregnant women …
