RESUMO
Background: The inclusion of milk in school feeding is accepted as good nutritional practice, but specific benefits remain uncertain. Objective: The objective was to determine whether consumption of 8.8 g milk protein/d given as milk powder with a multiple micronutrient-enriched porridge resulted in greater increases in linear growth and Cambridge Neuropsychological Test Automated Battery (CANTAB) scores in Ghanaian schoolchildren when compared with 1 of 3 control groups. Methods: A randomized, double-blind, placebo-controlled clinical trial in healthy children aged 6-9 y was conducted comparing 8.8 g milk protein/d with 4.4 g milk protein/d or 4.4 g milk protein + 4.4 g rice protein/d (isonitrogenous, half of the protein from milk and half from rice) or a non-nitrogenous placebo. Primary outcomes were changes in length after 9 mo and CANTAB scores after 4.5 mo; secondary outcomes were body-composition measures. Supplements were added to porridge each school day and consumed for 9 mo. Anthropometric and body-composition measures and CANTAB tests were completed upon enrollment and after 4.5 and 9 mo. Group results were compared by using ANCOVA for anthropometric measures and the Kruskal-Wallis test for CANTAB scores. Results: Children receiving 8.8 g milk protein/d showed greater increases on percentage correct in Pattern Recognition Memory (mean ± SD: 5.5% ± 16.8%; P < 0.05) and Intra/Extradimensional Set Shift completed stages compared with all other food groups (0.6 ± 2.3; P < 0.05). No differences were seen in linear growth between the groups. The children receiving either 4.4 or 8.8 g milk protein/d had a higher fat-free body mass index than those who received no milk, with an effect size of 0.34 kg/m2. Conclusion: Among schoolchildren, the consumption of 8.8 g milk protein/d improved executive cognitive function compared with other supplements and led to the accretion of more lean body mass, but not more linear growth. This trial was registered at www.clinicaltrials.gov">www.clinicaltrials.gov as NCT02757508.

OBJECTIVES: The objective of this study was to describe the use of telemedicine for contraception in a sample of young adults and examine differences by health insurance coverage. STUDY DESIGN: We analyzed survey data collected from May 2020 to July 2022 from individuals at risk of pregnancy aged 18 to 29 recruited at 29 community colleges in California and Texas. We used multivariable mixed-effects logistic regression models with random effects for site and individual to compare the use of telemedicine to obtain contraception by insurance status, sociodemographic characteristics, and state. RESULTS: Our analytic sample included 6465 observations from 1630 individuals. Participants reported using a contraceptive method obtained through telemedicine in just 6% of observations. Uninsured participants were significantly less likely than those privately insured to use contraception obtained through telemedicine (adjusted odds ratio [aOR], 0.54; 95% confidence interval [CI], 0.31-0.97), as were participants who did not know their insurance status (aOR, 0.54; 95% CI, 0.29-0.99). Texas participants were less likely to use contraception obtained via telemedicine than those in California (aOR, 0.42; CI: 0.25-0.69). CONCLUSIONS: Few young people in this study obtained contraception through telemedicine, and insurance was crucial for access in both states. IMPLICATIONS: Although telemedicine holds promise for increasing contraceptive access, we found that few young adults were using it, particularly among the uninsured. Efforts are needed to improve young adults' access to telemedicine for contraception and address insurance disparities.
