This study examined relations between caregiver feeding behaviours, child dietary diversity and anthropometry at 24 months of age in rural Bangladesh. Twenty-four hours dietary recall, weight and length data were collected on 4733 children. Factor analysis was applied to an 11-item caregiver feeding behaviours scale administered at 24 months, revealing two constructs: responsive/involved (five items) and forceful (six items); each dichotomised to reflect low and high use.

Background: Few studies have evaluated the dietary impact of complementary food supplements (CFSs) designed to deliver macro- and micronutrients to children at risk for undernutrition. In a randomized controlled trial in rural Bangladesh, we previously reported that CFSs increased children's micronutrient adequacy.

Objectives: To longitudinally characterize energy and macronutrient intakes and inadequacies and evaluate the extent to which CFSs fill intake gaps.

Article Synopsis
  • Shortwave infrared (SWIR) light emitters and detectors are important for various applications but currently depend on expensive semiconductors like InGaAs, which are hard to integrate with existing silicon technology.
  • Colloidal quantum dots (CQDs) represent a cheaper alternative but often contain harmful heavy metals, which limits their use.
  • The study presents a new method to create InAs/ZnSe core/shell quantum dots that improve performance in the SWIR range, with high efficiency and low dark current, successfully demonstrating their use in photodetectors.

Background: The increasing prevalence of diet-related non-communicable diseases (NCDs) in South Asia is concerning, with type 2 diabetes projected to rise to 68%, compared to the global increase of 44%. Encouraging healthy diets requires stronger policies for healthier food environments.

Methods: This study reviewed and assessed food environment policies in Bangladesh, India, Pakistan, and Sri Lanka from 2020 to 2022 using the Healthy Food Environment Policy Index (Food-EPI) and compared them with global best practices.

Article Synopsis
  • An estimated 5 billion people worldwide do not have access to safe surgical care, highlighting the need for increased interest in global surgery among medical students.
  • A survey of 708 medical students across 38 US institutions revealed that 34.6% expressed interest in global surgery, with demographic factors like Hispanic/Latino ethnicity and birthplace influencing this interest.
  • Prior experience in low or middle-income countries, along with public health and international service activities, were significant predictors of students' interest in global surgery, suggesting that medical educators should enhance global health opportunities for students.

Background: Savory crispy or fried snack (SCFS), sugary snack (SS), and sugar-sweetened beverage (SSB) consumption are associated with a higher prevalence of obesity and non-communicable diseases. So, we estimated the consumption of SCFS, SS, and SSB among elderly males and females in Bangladesh. We also reported the factors associated with their consumption using data from a nationwide cross-sectional study.
