Internet-Based Physical Activity Interventions

This article provides a comprehensive review of Internet– and Website–based physical activity interventions targeting adult populations. Search procedures identified 72 unique Internet-based physical activity interventions published in peer-reviewed journals. Participants of the studies were predominately White, middle-aged (mean age = 43.3 years), and female (65.9%). Intervention durations ranged from 2 weeks to 13 months (median = 12 weeks). Forty-six of the studies were randomized controlled trials, 21 were randomized trials without a control condition, 2 were non–randomized controlled trials, and 3 used a single-group design. The majority of studies (n = 68) assessed outcomes immediately following the end of the intervention period, and 16 studies provided delayed postintervention assessments. Forty-four of the 72 studies (61.1%) reported significant increases in physical activity. Future directions for Internet-based physical activity interventions include increasing representation of minority and male populations in Internet-based efforts, conducting delayed postintervention follow-up assessments, and incorporating emerging technologies (ie, cellular and Smartphones) into Internet-based physical activity efforts.

Using web-based technology to promote physical activity in Latinas: Results of the Muévete Alabama pilot study

Latinas in the US report high levels of physical inactivity and are disproportionally burdened by related health conditions (eg, type 2 diabetes, obesity), highlighting the need for innovative strategies to reduce these disparities. A 1-month single-arm pretest-posttest design was utilized to assess the feasibility and acceptability of a culturally and linguistically adapted Internet-based physical activity intervention for Spanish-speaking Latinas. The intervention was based on the Social Cognitive Theory and the Transtheoretical Model. Changes in physical activity and related psychosocial variables were measured at baseline and the end of the 1-month intervention. The sample included 24 Latina adults (mean age, 35.17 ± 11.22 years). Most (83.3%) were born outside the continental US. Intent-to-treat analyses showed a significant increase (P = .001) in self-reported moderate- to vigorous-intensity physical activity from a median of 12.5 min/wk at baseline to 67.5 min/wk at the 1-month assessment. Participants reported significant increases in self-efficacy as well as cognitive and behavioral processes of change. Nearly half of the participants (45.8%) reported advancing at least one stage of change during the course of the 1-month intervention. Findings support the feasibility and acceptability of using interactive Internet-based technology to promote physical activity among Latinas in Alabama.

Utility of Acculturation in Physical Activity Research in Latina Adults An Integrative Review of Literature

Latina adults in the United States have a disproportionately higher prevalence of chronic diseases related to low physical activity levels than non-Hispanic women. Literature indicates that acculturation may be a contributing factor to being physically active, but the extent of this association remains unclear. An integrative review of literature was conducted on studies that examined acculturation as it relates to physical activity in Latinas in the United States. Our review of 33 studies revealed inconsistent measurement and conceptualization of acculturation and physical activity across studies. Findings from this review reinforce the importance and continued use of acculturation by behavioral researchers; however, acculturation, as conceptualized in the studies reviewed, may not have had an influence on health as much as traditions, life patterns, and resources of Latinas.

Applying Psychological Theories to Promote Long-Term Maintenance of Health Behaviors

Behavioral health theory provides a framework for researchers to design, implement, and evaluate the effects of health promotion programs. However, limited research has examined theories used in interventions to promote long-term maintenance of health behaviors. The purpose of this review was to evaluate the available literature and identify prominent behavioral health theories used in intervention research to promote maintenance of health behaviors. We reviewed theories used in intervention research assessing long-term maintenance (≥6 months postintervention) of physical activity, weight loss, and smoking cessation. Five prominent behavioral theories were referenced by the 34 studies included in the review: self-determination theory, theory of planned behavior, social cognitive theory, transtheoretical model, and social ecological model. Descriptions and examples of applications of these theories are provided. Implications for future research are discussed.

Acculturation and Physical Activity Among Latinas Enrolled in a 12-Month Walking Intervention

This report evaluates the relationship between acculturation and assimilation with the physical activity (PA) outcomes of a 12-month walking intervention for postpartum Latinas (n = 81, M age = 29.2 years, M BMI [body mass index] = 30.0). PA was measured by ActiGraph GT1M accelerometers. Acculturation and assimilation were measured by the Hazuda Acculturation and Assimilation Scales. Data were collected at baseline, 6 months, and 12 months. Results showed a trend for participants classified in the least acculturated groups to engage in more moderate-to-vigorous PA than participants classified in the higher acculturated/assimilated groups for two dimensions of acculturation (Adult Proficiency in English Versus Spanish, p = .002; Adult Pattern of English Versus Spanish Language Usage, p = .001) and two dimensions of assimilation (Childhood Interaction With Members of Mainstream Society, p = .028; Adult Functional Integration With Mainstream Society, p ≤ .001). No other significant effects were observed. Findings highlight the continued need to understand the context in which acculturation and assimilation influence PA.

Rationale, design, and baseline findings from a pilot randomized trial of an IVR-Supported physical activity intervention for cancer prevention in the Deep South: The DIAL study

Telephone-delivered interventions do not require frequent clinic visits, literacy, or costly technology and thus may represent promising approaches to promoting physical activity in the Deep South, a largely rural U.S. region, with generally lower physical activity, income, and education levels. Building on past Interactive Voice Response (IVR) system-based HIV studies and extensive formative research (11 focus groups on physical activity intervention needs/preferences in the Deep South), the resulting IVR-supported physical activity intervention is now being tested in a randomized controlled trial with a waitlist control. The sample (n = 63) includes mostly obese (Mean BMI = 30.1) adults (Mean age = 43 years) in Birmingham, AL. Both genders (55.6% male) and African Americans (58.7%) are well-represented. Most participants reported at least some college (92%), full time employment (63.5%), and household income <

Telehealth intervention for Latina breast cancer survivors: A pilot:

50,000 per year (61.9%). Baseline physical activity (Mean = 39.6 min/week, SD = 56.4), self-efficacy, self-regulation, and social support were low. However, high physical activity enjoyment and outcome expectations bode well. Self-report physical activity was associated with physical activity enjoyment (r = 0.36) and social support (friends r = 0.25, ps < 0.05) at baseline. Consequently, these may be important variables to emphasize in our program. Depression and anxiety were negatively correlated with some early indicators of behavior change (e.g., physical activity self-regulation; rs = -0.43 and −0.46, respectively, ps < 0.01) and thus may require additional attention. Such technology-supported strategies have great potential to reach underserved populations and address physical activity-related health disparities in this region.

The Use of Family Rituals in Eating Behaviors in Hispanic Mothers

Aim: This study was a pilot test of the Latina Breast Cancer Survivorship Intervention, a survivorship self-management intervention delivered via telephone. Materials and methods: This study used a wait-list control design with random assignment to either (1) support and early education or (2) support and delayed education. Latina breast cancer survivors were recruited through the Florida Cancer Data System Registry. Latinas with stage I–III breast cancer who completed primary cancer treatment 3 years prior to study enrollment were eligible. The Latina Breast Cancer Survivorship Intervention consisted of three education sessions delivered weekly via telephone and six telephone support calls, both delivered by a native Spanish speaker. Primary outcome variables included physical well-being, emotional well-being, fatigue, pain, and depressive symptoms. Data collection occurred at baseline, 3 months, and 6 months. Results: In total, 40 Latina breast cancer survivors who were middle-aged to older, married, with health insurance, and Spanish as preferred language enrolled in the Latina Breast Cancer Survivorship Intervention. Data were analyzed using mean change scores. Overall, physical and emotional well-being remained similar over time with well-being scores poorer compared with the general population. Pain levels improved over 6 months and showed a high effect size. Fatigue scores improved at 3 months and showed a moderate effect size. Depressive symptoms remained elevated but were not clinically significant. Conclusion: Telephone-based Latina Breast Cancer Survivorship Intervention reached Latina breast cancer survivors for survivorship education and support. Self-management of pain and fatigue showed improvement over time.

Physical activity and quality of life among university students: exploring self-efficacy, self-esteem, and affect as potential mediators.

Food rituals often abruptly change when Hispanic families migrate to the United States. This report describes changes in rituals of food procurement, preparation, and presentation (food-PPP) in Hispanic women following migration to the United States. Focus groups and face-to-face interviews were conducted with 13 low-income, overweight/obese Hispanic women 27 to 40 years of age. Content analysis was used to analyze cultural and contextual sources for food-PPP. Changes in rituals and traditions in food-PPP occurred, including materials and ingredients for traditional meals. Food rituals may play a role in healthful eating and could, therefore, serve as leverage points for interventions designed to promote healthy eating behaviors.
