The collegiate environment may exacerbate body image issues and eating disorders (EDs) among dancers. This study seeks to evaluate the complex relationships between body image perceptions, risk of EDs, and nutrition knowledge among collegiate dancers. A convenience sample of collegiate dancers was recruited via announcements, flyers, and email to complete the Body Image Assessment Scale-Body Dimensions (BIAS-BD), anthropometrics, and an electronic survey evaluating ED risk (Eating Attitudes Test; EAT-26), nutrition knowledge, and dietary habits.

It is unknown if fibre intake differs across diabetes status in USA adults and is associated with glycaemic outcomes. This cross-sectional analysis utilised National Health and Nutrition Examination Survey cycles 2013-2018 data to estimate usual total dietary fibre intake in USA adults and across diabetes status (no diabetes, prediabetes and type II diabetes (T2D)). Associations among dietary fibre intake and glycaemic outcomes were also reported across groups.

Breastfeeding is the optimal source of infant nutrition, yet the mother's decision to breastfeed is complex and influenced by factors including social support and breastfeeding knowledge and attitudes. This study employed a two-group pretest-posttest design to examine whether brief, online video presentations (<2.5 minutes in length) could improve breastfeeding knowledge and attitude among males and compare the outcomes between a knowledge-based and attitude-based intervention.

Communications media that fails to present information supported by evidence-based practice has the potential to adversely influence knowledge and, ultimately, behaviors. We assessed the immediate effect of a health science documentary on knowledge, attitude, and beliefs among collegiate health sciences students enrolled in an entry-level nutrition course using surveys administered online. Participants (n = 160) completed the pre-survey, watched the documentary What the Health, and immediately completed the post-survey in one setting.

Background: Human milk is the preferred source of infant nourishment; yet, acceptance of human milk as the norm for infant feeding is debated. In the United States there is a disparity in breastfeeding rates, which are significantly lower in African Americans compared to Whites. Multiple variables appear to influence breastfeeding, including the male partner.

Background: Researchers exploring breastfeeding attitudes and knowledge among women suggest the decision to breastfeed is influenced by the male partner, yet few studies address males. Because collegiate males will soon enter fatherhood, assessment of their attitudes and knowledge may inform interventions aimed at increasing intention to breastfeed.

Research Aim: This study aimed to describe collegiate males' exposure to, attitude toward, and knowledge about breastfeeding.

We compared calcium (Ca) sources and intake, as well as multivitamin/mineral supplement use between female students with nutrition/health background and those from general-student-populations. 314 participants 18-37 y, including 57 African-Americans and 54 Caucasian-Americans recruited from Nutrition and/or other Health Sciences departments (NHS), and 100 African-American and 103 Croatian women representing general-student-population (GSP), completed food frequency questionnaire assessing their usual Ca intake and supplement use. NHS populations met recommendations and consumed significantly more Ca, particularly from dairy sources, and were more likely to take supplements than GSP groups, suggesting that health education may influence Ca intake.

The objective of this study was to assess the effects of weight history status and ethnicity on the ability of the Harris Benedict (HB) formula to: 1) predict measured resting energy expenditure (REE), and, 2) accurately estimate energy needs over a 2-week test period. Subjects were never-overweight (BMI View Article and Find Full Text PDF

Objective: To test the hypothesis that the dietary intake and dietary composition of women with polycystic ovary syndrome (PCOS) is associated with indices of glycemic status. We hypothesized that women with PCOS would consume a diet higher in total energy, fat, and specific foods with a high glycemic index than would healthy, control-group women and that dietary composition would be associated with indices of insulin resistance and secretion among women with PCOS.

Design: Cohort study.

Objective: To determine whether eucaloric diets either enriched with monounsaturated fatty acids (MUFA; 17% energy) or low in carbohydrates (Low CHO; 43% energy) would increase insulin sensitivity (Si) and decrease circulating insulin concentrations, relative to a standard diet (STD; 56% CHO, 31% fat, 16% protein), among women with polycystic ovary syndrome (PCOS).

Design: Crossover.

Setting: Academic research environment.
