RESUMEN
Mexican Americans are among the highest risk groups for obesity and its associated health consequences, including diabetes, heart disease, and cancer. 154 overweight/obese Mexican Americans recruited from the Mexican Consulate in New York City were enrolled in COMIDA (Consumo de Opciones Más Ideales De Alimentos) (Eating More Ideal Food Options), a 12-week Spanish-language lifestyle intervention that included a dietary counseling session, weight-loss resources, and thrice-weekly text messages. Participants' weight (primary outcome); dietary intake, physical activity, and nutrition knowledge (secondary outcomes) were assessed pre- and post-intervention. Of the 109 who completed follow-up, 28% lost ≥ 5% of their baseline body weight. Post-intervention, participants consumed more fruit and less soda, sweet pastries, fried foods and red meat; increased physical activity; and evidenced greater nutrition knowledge. A community-based lifestyle intervention with automated components such as text messaging may be a scalable, cost-effective approach to address overweight/obesity among underserved populations.
RESUMEN
Mexican Americans are at increased risk for obesity upon immigration to the U.S., increasing their risk for diabetes, cardiovascular disease, and cancer. Our pilot individual lifestyle intervention culturally tailored for Mexican Americans, COMIDA (Consumo de Opciones Más Ideales De Alimentos) (Eating More Ideal Food Options), showed promising results. This paper presents outcomes from the group-based version of COMIDA. 129 overweight/obese Mexican Americans were enrolled in 'Group COMIDA'. Participants' weight (primary outcome), dietary intake and nutrition knowledge (secondary outcomes) were assessed pre- and post-intervention. Seventeen percent of participants experienced 5% weight loss at follow-up. Post-intervention, participants consumed more fruit and vegetables and fewer sweets and fried foods. A group-based, culturally adapted lifestyle intervention may be a more cost-effective approach than individual interventions to improve dietary behavior among underserved populations, though additional modifications may be considered to increase the intervention's effectiveness in promoting significant weight loss.

INTRODUCTION: Hispanics are the largest minority group in the United States, constituting 18 % of the population. Mexicans are the largest Hispanic subgroup and are at disproportionate risk for overweight/obesity. Lifestyle interventions targeting dietary change and physical activity have resulted in significant weight loss in several large randomized clinical trials in the general population, but few studies have tailored interventions to Mexican Americans. We conducted a community needs assessment from 2018 to 2020 in accordance with Domenech-Rodriguez and Wieling's Cultural Adaptation Process (CAP) model to inform the development of SANOS (SAlud y Nutrición para todOS) (Health and Nutrition for All), a culturally-tailored, community-based diet and lifestyle education and counseling program that addresses overweight/obesity among U.S. Mexicans. METHODS: Five Spanish-language focus groups were conducted until thematic saturation with 31 overweight/obese Mexicans in New York City about their knowledge, priorities, and preferences regarding diet, exercise, and evidence-based strategies for behavioral change. A grounded theory approach was used to analyze the data. RESULTS: Five themes were identified: (1) A strong desire for tangible information related to diet and health, (2) Family as a primary motivator for behavior change, (3) Desire for group-based motivation and accountability to sustain intervention participation, (4) Belief in short-term goal setting to prevent loss of motivation, and (5) Time and workplace-related barriers to intervention adoption. CONCLUSIONS: Ecological factors such as the effect of acculturation on diet, family members' role in behavior change, and socioenvironmental barriers to healthy dietary practices and physical activity should be considered when adapting evidence-based treatments for Mexican Americans.
