Review of recent innovations in portable child growth measurement devices for use in low- and middle-income countries.

Improving nutritional status is fundamental to addressing challenges in child health in low- and middle-income countries (LMICs) and a priority for international organisations such as the United Nations Children's Fund (UNICEF) and the World Health Organisation (WHO). Despite the global consensus that child growth is a key indicator of child nutrition and health, the development of low-cost, accurate and child-friendly growth measurement devices that are fit for purpose in LMICs remains elusive. Recognising these limitations, UNICEF recently published a Target Product Profile (TPP) calling for the development of new state-of-the-art height and length measurement devices. The purpose of this review was to examine current growth measurement devices in relation to this UNICEF TPP requirement and set the stage for the development of new devices. The findings show that there is a gap in the product market for accurate portable length and height measurement devices. In particular, our review indicates that devices in current use generally lack capabilities for automated data recording and transfer of data to a central database, and are often not child-friendly. We conclude that future innovations in length and height measurement devices should focus on addressing these issues.

The effects of a multi-ingredient dietary supplement on body composition, adipokines, blood lipids, and metabolic health in overweight and obese men and women: a randomized controlled trial.

BACKGROUND: The present study investigated the effects of a multi-ingredient dietary supplement (MIDS) containing caffeine, conjugated linoleic acid (CLA), green tea, and branched-chain amino acids (BCAA) taken for 8 weeks on body composition, blood lipid profile, glucose, insulin, adiponectin, leptin, and high-sensitivity C-reactive protein (hs-CRP) in overweight and obese men and women. METHODS: Twenty-two participants completed the study (PL, n = 11; 7 women, 4 men; age, 34 ± 3.5 years; height, 169.2 ± 3.3 cm; body mass, 96.9 ± 6.8 kg; BMI, 34.1 ± 1.8 kg/m(2); MIDS, n = 11; 9 women, 2 men; age, 36 ± 3.4 years; height, 173.2 ± 2.9 cm; body mass, 91.9 ± 5.6 kg; BMI, 30.0 ± 1.5 kg/m(2)). Participants were randomly assigned and stratified by body fat percentage to two groups: 1) a soybean oil placebo (PL) or 2) MIDS. Each group consumed two pills with breakfast and two pills with lunch. Body composition and android fat, waist and hip circumferences, blood pressure and heart rate were measured at baseline and after 8 weeks of supplementation. RESULTS: There were no significant changes for any of the variables of body composition. Feelings of hunger were significantly higher in MIDS versus PL with no changes observed in satiety or desire to eat. Heart rate and blood pressure were unaltered in MIDS after 8 weeks of supplementation. Furthermore, lipid profile, food intake, mood state variables, fasting blood glucose, and endocrine markers did not significantly change regardless of group. CONCLUSION: MIDS intake does not appear to alter body composition or markers of cardiovascular health versus PL. Moreover, MIDS may actually increase feelings of hunger versus PL.
