Randomized Controlled TrialCalcium Plus Vitamin D Supplementation During the Third Trimester of Pregnancy in Adolescents Accustomed to Low Calcium Diets Does Not Affect Infant Bone Mass at Early Lactation in a Randomized Controlled Trial.
Pregnancy and lactation in adolescents with low calcium intake may impair fetal growth and infant bone mass. ⋯ Calcium and vitamin D supplementation of the adolescents studied resulted in higher fetal body weight at 36 wk of gestation and had no effect on infant bone mass at 5 wk postpartum. Because correlations between maternal and infant bone mass were evident only in the placebo group, infant bone mass appeared to be more dependent on maternal skeletal mass when calcium intake was low. This trial was registered at clinicaltrials.gov as NCT01732328.

Observational StudyA Healthy Lifestyle Score Is Associated with Cardiometabolic and Neuroendocrine Risk Factors among Puerto Rican Adults.
Although individual healthy lifestyle behaviors may reduce cardiovascular disease risk, few studies have analyzed the combined effect of multiple lifestyle components as one all-inclusive measure on such outcomes, much less in minority populations. ⋯ Following an overall healthy lifestyle that comprises a combination of multiple behaviors may provide stronger protection against MetS and AL in Puerto Rican adults than individual components. The HLS may be a useful tool for examining health-related outcomes. This trial was registered at clinicaltrials.gov as NCT01231958.

Comparative StudyHousehold Food Insecurity Is a Stronger Marker of Adequacy of Nutrient Intakes among Canadian Compared to American Youth and Adults.
The most recent statistics indicate that the prevalence of food insecurity in the United States is double that in Canada, but the extent to which the nutrition implications of this problem differ between the countries is not known. ⋯ This study suggests that household food insecurity is a stronger marker of nutritional vulnerability in Canada than in the United States. The results highlight the need for research to elucidate the effects of domestic policies affecting factors such as food prices and fortification on the nutritional manifestations of food insecurity.
