Breast cancer is the most common cancer among Latina women, and Latina women are at higher risk for breast cancer mortality than white women. Lifestyle factors, such as consuming a nutritious diet and engaging in regular physical activity, promote health and are protective against heart disease, type 2 diabetes, and breast cancer recurrence. Previous studies have developed and tested interventions for Latina breast cancer survivors to improve diet and increase physical activity, however, no studies to date have developed a smartphone delivered intervention. The purpose of the current study was to compare two Smartphone delivered interventions, My Health, which focused on diet and physical activity, and My Guide, which focused on psychosocial functioning, on dietary and physical activity outcomes, post-intervention, and at a 2-week follow-up assessment. Overall, participants receiving the My Health intervention reported a greater reduction in daily fat sources than the My Guide group over time. However, daily sources of fat did not differ between conditions. Walking, measured by estimated weekly metabolic equivalents, increased across time points in both groups. These preliminary findings suggest that eHealth interventions aimed at improving lifestyle factors may favorably impact nutritional intake and physical activity. Future research should utilize more comprehensive and objective measures of diet and physical activity, and incorporate more behavioral lifestyle components into the intervention in larger samples with a longer follow-up period.
乳腺癌是拉丁裔女性中最常见的癌症，拉丁裔女性死于乳腺癌的风险比白人女性更高。生活方式因素，如食用营养饮食和定期进行身体活动，可促进健康，预防心脏病、2 型糖尿病和乳腺癌复发。先前的研究已经针对拉丁裔乳腺癌幸存者制定并测试了改善饮食和增加身体活动的干预措施，但迄今为止尚无研究开发智能手机提供的干预措施。本研究的目的是比较两种智能手机提供的干预措施，My Health 专注于饮食和身体活动，以及 My Guide 专注于心理社会功能，以评估干预后的饮食和身体活动结果，以及 2 周的随访评估。总的来说，与 My Guide 组相比，接受 My Health 干预的参与者在一段时间内报告的每日脂肪来源减少更多。然而，两组之间的每日脂肪来源没有差异。两组的步行量（通过估计每周代谢当量测量）均随时间增加。这些初步结果表明，旨在改善生活方式因素的电子健康干预措施可能对营养摄入和身体活动产生有利影响。未来的研究应在更大的样本量和更长的随访期内，利用更全面和客观的饮食和身体活动措施，并将更多行为生活方式因素纳入干预措施中。
