Differences in health-related behaviors and body mass index risk categories in African American women in college

Social and Religious Networks with Respect to the Health Behaviors of African American Women: A Systematic Review

The aim of this systematic mixed studies review was to examine how social networks influence physical activity and dietary patterns among African American women. We searched PUBMED, CINAHL, JSTOR, SocioIndex, Medline, Cochrane Library, sportDISCUS, and PsycINFO to review articles published between Jan 1, 2007, and July 1, 2021. Only 23 studies met the inclusion criteria. All studies were conducted in the US. Social support received from family members, friends, and churches was found to positively influence physical activity and/or dietary patterns among African American women. An inconsistent relationship was found between social network size, health behavior characteristics of social networks, and physical activity and/or dietary patterns among African American women. Future research should incorporate structural and functional social network strategies to promote physical activity and healthy eating behaviors effectively and sustainably among African American women.

Dietary and Lifestyle Risk Factors of Obesity Among Young Adults: A Scoping Review of Observational Studies

PURPOSE OF REVIEW

Obesity is a growing public health concern worldwide, especially among young adults. This scoping review aims to identify and summarize the current evidence on dietary and lifestyle risk factors associated with obesity among young adults.

RECENT FINDINGS

A scoping review was performed using the PRISMA-ScR guidelines. A systematic search of five electronic databases published from inception to October 2023 was conducted. A total of 46 observational studies met the inclusion criteria and were included in the review. The findings suggest that high intake of energy-dense foods, unhealthy eating habits, poor sleep quality, and increased screen time were significant risk factors for obesity among young adults. In contrast, the association between obesity and sedentary behavior, low physical activity levels, alcohol consumption, and smoking habits was inconclusive. The reviewed evidence suggests that unhealthy dietary habits and lifestyle behaviors are associated with an increased risk of obesity among young adults. The findings highlight the need for further research on these modifiable risk factors to prevent and manage obesity among young adults.

Associations between lifestyle factors and body mass index in African-American community college students

The goal was to examine associations between body mass index (BMI) and lifestyle factors in African American community college students. Methods: Young adults, 18-25, who identified as African American were eligible to participate from 3/17 to 11/17. BMI, body image, discrimination, social roles, emotional and informational support, nutrition knowledge, and physical activity were assessed. Results: Data from 323 students were analyzed. The mean age was 20.1 ± 2.0 years. There were no significant differences between individuals with BMI ≥ 25 and BMI < 25 on social role satisfaction, discrimination, and emotional or informational support. Overweight/obese individuals rated themselves higher on body image than normal weight individuals. The association between ideal body image and BMI sustained after adjusting for various factors. Conclusions: This is a unique population and they have unique needs in weight loss interventions. The strong relationship between body image and BMI suggests that incorporating body image into intervention design may assist in weight loss.

Effect of BMI and Perceived Importance of Health on the Health Behavior of College Students: Cross-Sectional Study

BACKGROUND

Both body mass index (BMI) and the perceived importance of health have received a lot of attention, but few studies have fully investigated the interaction of their effects on health behaviors.

OBJECTIVE

This study investigates the effects of BMI and the perceived importance of health on health behaviors (patterns of eating, sleeping, and exercising) among college students in Taiwan.

METHODS

A survey was conducted with 334 students to assess their perception of the importance of health (using indicators) and their health behavior (using the Health Behaviors Scale). Respondent BMI was calculated from self-reported body weight and height. Descriptive statistical analysis, independent t test analysis, two-way analysis of variance (ANOVA), and one-way ANOVA were conducted.

RESULTS

The results showed a significant difference between genders in health behaviors among college students (eating: t₃₃₂=2.17, P=.03; exercise: t₃₃₂=5.57, P<.001; sleep: t₃₃₂=2.58, P=.01). Moreover, there was an interaction between BMI and perception (of the importance of health) for exercise behaviors (F_2,328=3.50, P=.03), but not for eating behaviors (F_2,328=0.12, P=.89) or sleep behaviors (F_2,328=1.64, P=.20).

CONCLUSIONS

This study establishes, for the first time, the interaction of BMI and the perceived importance of health on health behaviors. The perception of health was found to have a significant effect on exercise behaviors. Thus, the perception of health plays a significant role in the exercise behaviors of college students in Taiwan. This finding provides researchers, policy makers, and practitioners with evidence, and consequently, opportunities for focusing on preventive actions. The findings suggest that increasing the importance of health in the perception of college students, should be the focus of efforts to help students exercise more regularly.

The Associations between Individual Factors, eHealth Literacy, and Health Behaviors among College Students

Background: This study aimed to investigate the associations between individual factors, electronic health (eHealth) literacy, dietary behaviors, and exercise habits in college students, as well as the moderating effect of gender on the above target behaviors. Methods: A pen-and-paper questionnaire with a stratified sampling method was used to collect data, and at least 100 students from each stratum were determined to be used for the official sample in this study. Finally, 674 students completed the survey. Results and Conclusions: Chi-square test results demonstrated that genders had dissimilar dietary supplement use and subjective health status. Further analyses indicated females had a higher likelihood of taking dietary supplements and poorer subjective health statuses. The t-test results indicated that the functional eHealth literacy, dietary behaviors, and exercise habits of genders were different, and the mean scores showed that males had higher functional eHealth literacy, healthier dietary behaviors, and higher exercise involvement than females. Regression analyses showed that students who were male, took dietary supplements, placed the utmost importance on health, and had high critical eHealth literacy tended to possess healthy dietary behaviors. Students who were male and had good subjective health statuses tended to have higher exercise involvement. Specifically, the critical eHealth literacy changed dietary behaviors less effectively for women than for men, and the subjective health status changed exercise habits less effectively for women than for men. Therefore, when designing the diet and exercise intervention programs, gender-specific programs rather than generic programs should be given priority to develop.

A Question of Color

This study describes the relative influence of facial skin color, lifetime exposure to racial discrimination, chronic stress, and traditional prehypertension risk factors (family history of hypertension and age) on resting blood pressure and body mass index (BMI) among 196 southern African American (AA) female undergraduate students. Stepwise regression analyses indicated that skin color was the strongest predictor of systolic blood pressure (SBP), diastolic blood pressure (DBP), and BMI. Skin color, chronic stress, and family history of hypertension predicted 53% of the SBP variance. Skin color, chronic stress, and family history of hypertension predicted 30.2% of the DBP variance. Racism and age were not significant predictors of SBP or DBP. Of the variance in BMI, 33% was predicted by skin color, chronic stress, and racism. Age and family history of hypertension were not predictors of BMI. The current study provides evidence of the relationship of skin color and chronic stress to blood pressure among young southern AA women. The study identifies an important relationship between increased racial stress exposure and heavier BMIs, a predictor of prehypertensive risk.
