Perceived Barriers to Physical Activity Among Low-Income Latina Women at Risk for Type 2 Diabetes.

Purpose The purpose of this study was to examine perceived barriers to physical activity among low-income Latina women who were at risk for type 2 diabetes, as well as the demographic factors that influence these perceived barriers. Methods Recruited in the waiting room of a community health center in a low-income neighborhood (n = 160), Latina women between the ages of 18 and 49 years completed a survey to assess demographic characteristics and perceived barriers to physical inactivity. Descriptive statistics, chi-square tests, and multivariate regression analyses were conducted to identify barriers to physical activity and the associations between demographic factors and perceived barriers. Results The most commonly perceived barriers to physical activity in the study sample were lack of willpower and lack of energy. After adjusting for other characteristics, overweight/obese participants were more likely than women of normal weight to report social influence and fear of injury as important barriers to exercise. In addition, women whose preferred language was Spanish were more likely than women whose preferred language was English to perceive lack of time, and social influence as important barriers. Conclusions The effective encouragement of physical activity among Latina women at risk for type 2 diabetes must address the perceived barriers of lack of willpower and lack of energy. Although all women at risk for type 2 diabetes could benefit from counseling and other strategies to encourage physical activity, these efforts should be targeted toward Spanish-speaking overweight/obese women, who are more likely to perceive barriers to exercise.

Effective Translation of an Intensive Lifestyle Intervention for Hispanic Women With Prediabetes in a Community Health Center Setting.

OBJECTIVE: The Diabetes Prevention Program (DPP) demonstrated that weight loss from intensive lifestyle intervention (ILI) in adults with prediabetes could decrease progression to type 2 diabetes. Inner-city, low-income Hispanic women are at high risk for developing type 2 diabetes; however, this type of intervention is not well established in this group. We hypothesized that a DPP intervention modified for a community health center (CHC) setting would decrease weight and improve metabolic measures in Hispanic women with prediabetes. RESEARCH DESIGN AND METHODS: Women diagnosed with prediabetes on a screening oral glucose tolerance test were recruited from a CHC. Participants (90% of whom were Hispanic) were randomized to either usual care (age 43 ± 9.7 years, BMI 35.2 ± 7.3 kg/m(2)) or ILI (age 43.8 ± 10.8 years, BMI 35.4 ± 8.5 kg/m(2)), structured as 14 weeks of group sessions focused on food choices, behavior change, physical activity, and weight loss. One year after enrollment, 122 women repeated baseline measures. RESULTS: Groups had similar baseline weight, BMI, and fasting and 2-h glucose. One year later, the ILI group had lost 3.8 kg (4.4%), while the usual care group had gained 1.4 kg (1.6%, P < 0.0001). Two-hour glucose excursion decreased 15 mg/dL (0.85 mmol/L) in the ILI and 1 mg/dL (0.07 mmol/L) in the usual care group (P = 0.03). Significant decreases favoring the ILI group were noted in BMI, percent body fat, waist circumference, and fasting insulin. CONCLUSIONS: A 14-week ILI program based on the DPP can effectively be translated into a predominantly Hispanic CHC setting, resulting in decreased weight, improved fasting insulin, and smaller glucose excursions 1 year after enrolling in the program.

Preventing diabetes among Fair Haven families: a community-based approach to quality improvement.

In this paper, we describe our efforts to integrate the Diabetes Prevention Program and the Bright Bodies program into a coordinated intensive lifestyle intervention program for families living in Fair Haven, an underserved Hispanic neighborhood in New Haven, Connecticut with high rates of obesity and prediabetes in adults and children.

Implementation of a lifestyle program in primary care by nurse practitioners.

PURPOSE: The purpose of this study is to describe the implementation process and participant satisfaction with a lifestyle program provided by nurse practitioners (NPs) in primary care to adults at risk for type 2 diabetes (T2D) compared to enhanced standard care. DATA SOURCES: A mixed-method clinical trial design was used (n= 58). NPs were interviewed prior to beginning the program, at 3 months, and at completion of the program. NPs also completed a questionnaire on lifestyle counseling at baseline. Process data were collected on attendance, attrition, and intervention fidelity. Participants completed a satisfaction survey at completion of the program and a sub-sample were interviewed at the end of the program. CONCLUSIONS: NPs reported that they felt well-prepared and moderately effective in providing lifestyle change counseling. Participant attendance was high and in-person sessions were implemented with good success. Participants in the lifestyle program were more satisfied with the program, reporting that the program was a good experience. IMPLICATIONS FOR PRACTICE: Implementation of a lifestyle program to prevent T2D in primary care is feasible and acceptable to NPs and participants. Developing a structured program may improve health outcomes.
