Background: African American adults suffer disproportionately from obesity-related chronic diseases, particularly at younger ages. In order to close the gap in these health disparities, efforts to develop and test culturally appropriate interventions are critical. Methods: A PRISMA-guided systematic review was conducted to identify and critically evaluate health promotion interventions for African Americans delivered in barbershops and hair salons. Subject headings and keywords used to search for synonyms of ‘barbershops,’ ‘hair salons,’ and ‘African Americans’ identified all relevant articles (from inception onwards) from six databases: Academic Search Ultimate, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Embase, PsycINFO, PubMed, Web of Science (Science Citation Index and Social Sciences Citation Index). Experimental and quasi-experimental studies for adult (> 18 years) African Americans delivered in barbershops and hair salons that evaluated interventions focused on risk reduction/management of obesity-related chronic disease: cardiovascular disease, cancer, and type 2 diabetes were included. Analyses were conducted in 2020. Results: Fourteen studies met criteria for inclusion. Ten studies hosted interventions in a barbershop setting while four took place in hair salons. There was substantial variability among interventions and outcomes with cancer the most commonly studied disease state (n = 7; 50%), followed by hypertension (n = 5; 35.7%). Most reported outcomes were focused on behavior change (n = 10) with only four studies reporting clinical outcomes. Conclusions: Health promotion interventions delivered in barbershops/hair salons show promise for meeting cancer screening recommendations and managing hypertension in African Americans. More studies are needed that focus on diabetes and obesity and utilize the hair salon as a site for intervention delivery. Trial registration: PROSPERO CRD42020159050.

Hispanic males have the highest prevalence of overweight and obesity among men in the United States; yet are significantly underrepresented in weight loss research. The purpose of the current study was to examine Hispanic male’s perspectives of health behaviors related to weight management to refine the methodologies to deliver a gender-sensitive and culturally sensitive weight loss intervention. From October 2014 to April 2015, semistructured interviews were conducted with 14 overweight Hispanic men of ages 18 to 64 years. The interviews lasted approximately 60 minutes. Participants also completed a brief questionnaire and body weight/height were measured. Grounded in a deductive process, a preliminary codebook was developed based on the topics included in the interview guides. A thematic analysis facilitated the identification of inductive themes and the finalization of the codebook used for transcript analysis. Four overarching themes were identified: (a) general health beliefs of how diet and physical activity behaviors affect health outcomes, (b) barriers to healthy eating and physical activity, (c) motivators for change, and (d) viable recruitment and intervention approaches. Future research should examine feasible and appropriate recruitment and intervention strategies identified by Hispanic males to improve weight management in this vulnerable group.

The incidence of nonalcoholic fatty liver disease (NAFLD) is highest among Mexican‐origin (MO) adults. Few studies have estimated the prevalence of NAFLD in this subpopulation, particularly by sex and age. We assessed the prevalence of NAFLD in a community sample of MO adults residing in a border region of southern Arizona and determined risk factors associated with NAFLD. A total of 307 MO adults (n = 194 women; n = 113 men) with overweight or obesity completed an in‐person study visit, including vibration‐controlled transient elastography (FibroScan) for the assessment of NAFLD status. A continuous attenuation parameter score of ≥288 dB/m (≥5% hepatic steatosis) indicated NAFLD status. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for NAFLD. We identified 155 participants (50%) with NAFLD, including 52% of women and 48% of men; there were no sex differences in steatosis (men, 287.8 dB/m; women, 288.4 dB/m). Sex, age, patatin‐like phospholipase domain containing 3 ( PNPLA3 ) risk allele carrier status, comorbidities, and cultural and behavioral variables were not associated with NAFLD status. There was some evidence for effect modification of body mass index (BMI) by sex ( P interaction = 0.08). The estimated OR for an increase in BMI of 5 kg/m 2 was 3.36 (95% CI, 1.90, 5.91) for men and 1.92 (95% CI, 1.40, 2.64) for women. In post hoc analyses treating steatosis as a continuous variable in a linear regression, significant effect modification was found for BMI by sex ( P interaction = 0.03), age ( P = 0.05), and PNPLA3 risk allele carrier status ( P = 0.02). Conclusion: Lifestyle interventions to reduce body weight, with consideration of age and genetic risk status, are needed to stem the higher rates of NAFLD observed for MO populations.
