BackgroundBecause residents of the southeastern United States experience disproportionally high rates of cardiovascular disease (CVD), it is important to develop effective lifestyle interventions for this population.MethodsThe primary objective was to develop and evaluate a dietary, physical activity (PA) and weight loss intervention for residents of the southeastern US. The intervention, given in eastern North Carolina, was evaluated in a 2 year prospective cohort study with an embedded randomized controlled trial (RCT) of a weight loss maintenance intervention. The intervention included: Phase I (months 1–6), individually-tailored intervention promoting a Mediterranean-style dietary pattern and increased walking; Phase II (months 7–12), option of a 16-week weight loss intervention for those with BMI ≥ 25 kg/m2 offered in 2 formats (16 weekly group sessions or 5 group sessions and 10 phone calls) or a lifestyle maintenance intervention; and Phase III (months 13–24), weight loss maintenance RCT for those losing ≥ 8 lb with all other participants receiving a lifestyle maintenance intervention. Change in diet and PA behaviors, CVD risk factors, and weight were assessed at 6, 12, and 24 month follow-up.ResultsBaseline characteristics (N = 339) were: 260 (77 %) females, 219 (65 %) African Americans, mean age 56 years, and mean body mass index 36 kg/m2. In Phase I, among 251 (74 %) that returned for 6 month follow-up, there were substantial improvements in diet score (4.3 units [95 % CI 3.7 to 5.0]), walking (64 min/week [19 to 109]), and systolic blood pressure (−6.4 mmHg [−8.7 to −4.1]) that were generally maintained through 24 month follow-up. In Phase II, 138 (57 group only, 81 group/phone) chose the weight loss intervention and at 12 months, weight change was: −3.1 kg (−4.9 to −1.3) for group (N = 50) and −2.1 kg (−3.2 to −1.0) for group/phone combination (N = 75). In Phase III, 27 participants took part in the RCT. At 24 months, weight loss was −2.1 kg (−4.3 to 0.0) for group (N = 51) and −1.1 kg (−2.7 to 0.4) for combination (N = 72). Outcomes for African American and whites were similar.ConclusionsThe intervention yielded substantial improvement in diet, PA, and blood pressure, but weight loss was modest.Trial registrationclinicaltrials.gov Identifier: NCT01433484Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-016-3370-9) contains supplementary material, which is available to authorized users.
Participating in physical activity is beneficial for health. Whilst Aboriginal children possess high levels of physical activity, this declines rapidly by early adolescence. Low physical activity participation is a behavioral risk factor for chronic disease, which is present at much higher rates in Australian Aboriginal communities compared to non-Aboriginal communities. Through photos and ‘yarning’, the Australian Aboriginal cultural form of conversation, this photovoice study explored the barriers and facilitators of sport and physical activity participation perceived by Aboriginal children (n = 17) in New South Wales rural communities in Australia for the first time and extended the limited research undertaken nationally. Seven key themes emerged from thematic analysis. Four themes described physical activity barriers, which largely exist at the community and interpersonal level of children’s social and cultural context: the physical environment, high costs related to sport and transport, and reliance on parents, along with individual risk factors such as unhealthy eating. Three themes identified physical activity facilitators that exist at the personal, interpersonal, and institutional level: enjoyment from being active, supportive social and family connections, and schools. Findings highlight the need for ongoing maintenance of community facilities to enable physical activity opportunities and ensure safety. Children held strong aspirations for improved and accessible facilities. The strength of friendships and the family unit should be utilized in co-designed and Aboriginal community-led campaigns.
Background As Americans commonly consume restaurant foods with poor dietary quality, effective interventions are needed to improve food choices at restaurants. Purpose To design and evaluate a restaurant-based intervention to help customers select and restaurants promote heart healthy menu items with healthful fats and high quality carbohydrates. Methods The intervention included table tents outlining 10 heart healthy eating tips, coupons promoting healthy menu items, an information brochure, and link to study website. Pre and post intervention surveys were completed by restaurant managers and customers completed a brief “intercept” survey. Results Managers (n = 10) reported the table tents and coupons were well received, and several noted improved personal nutrition knowledge. Overall, 4214 coupons were distributed with 1244 (30%) redeemed. Of 300 customers surveyed, 126 (42%) noticed the table tents and of these, 115 (91%) considered the nutrition information helpful, 42 (33%) indicated the information influenced menu items purchased, and 91 (72%) reported the information will influence what they order in the future. Discussion The intervention was well-received by restaurant managers and positively influenced menu item selection by many customers. Translation to Health Education Practice Further research is needed to assess effective strategies for scaling up and sustaining this intervention approach.
There are serious health implications associated with pregnant women being overweight (BMI 25-29kg/m 2) (Lewis, 2007). Despite 'overweight/obesity' in pregnancy being highlighted in key government documents and research, the predominant focus is often on obesity (BMI ≥ 30kg/m 2). Women who are overweight (WO) tend to exceed the IOM weight gain guidelines (Phelan et al., 2011), compared to normal weight or obese women. Therefore, understanding the issues influencing dietary and physical activity choices for WO is crucial. Maternity staff can potentially influence behaviour change, so their experiences of providing support to WO, and the advice they provide to them was explored. 3 Candidate's Statement I declare that the work in this thesis was carried out in accordance with the regulations of the Sheffield Hallam University and is original except where indicated by the specific reference in the text.
