This study examined the effectiveness of a 6-month intervention to improve the health behaviors and outcomes among women aged 50 years and older. A sample of 580 (intervention n = 295; control n = 285) women was recruited from 26 recreational centers. Only the intervention group participated in the Singapore Physical Activity (PA) and Nutrition Study (SPANS), received health resources (calendar, recipe, and booklets) and motivational support from program ambassadors. The intervention group showed significant improvements in moderate-intensity PA, vigorous-intensity PA, and total PA ( P < .001), increased intake frequency of fruit and vegetables ( P = .049), a reduction in salt and sugary beverage intake ( P ≤ .042), and reductions in systolic blood pressure (BP; −3.68 mm Hg), diastolic BP (−3.54 mm Hg), and percentage body fat (−2.13%; P ≤ .020) when compared with the control group. The SPANS appeared to be efficacious in improving PA and dietary behaviors, reducing BP and percentage body fat among Singaporean women.

Purpose: To evaluate the effect of a 17-week intervention, including an after-school physical activity (PA) club 3 d/wk, on moderate-to-vigorous physical activity (MVPA), body mass index (BMI) z score, percentage body fat (%BF), and cardiorespiratory fitness (CRF) among fifth to eighth grade girls having a BMI z score ≥0, and explore whether intervention outcomes varied by club attendance (1 vs 2 vs 3 d/wk). Design: Secondary analysis of data from a group randomized controlled trial (N = 1519, 10- to 15-year-old girls: n = 753 intervention; n = 766 control). Setting: Twenty-four Midwestern US schools (n = 12 intervention; n = 12 control). Sample: Subsample (n = 1194 girls) from trial’s intervention (n = 593 girls) and control (n = 601 girls) groups having BMI z scores ≥0. Measures: Moderate-to-vigorous physical activity (min/h), BMI z score, %BF, and CRF ([Formula: see text]: mL/kg/min) were estimated at baseline and postintervention. Analysis: Linear mixed-effect models. Results: Intervention group gained less %BF ( B = −0.35, P = .016), and their CRF decreased less ( B = 0.22, P = .010) than the control. Marginally significant findings showed girls attending the club an average of 1 d/wk had greater increases in %BF ( B = 0.33, P = .087) and MVPA ( B = 0.20, P = .083) and a greater decrease in CRF ( B = −0.20, P = .061) than girls attending 3 d/wk. No differences occurred between girls who attended 2 versus 3 d/wk for any outcomes. Conclusions: The intervention attenuated an increase in %BF and a decrease in CRF among girls at risk for obesity from baseline to postintervention. Offering the after-school PA club 2 d/wk may be adequate for achieving outcomes.

Abstract Objectives The aim was to investigate the effect of physical activity on periodontal health and HbA1c levels in patients with type 2 diabetes mellitus (T2DM) over a period of 6 months. Materials and methods Thirty-seven patients with non-insulin-dependent T2DM were included in the study. The intervention group (n=20) performed physical activity over a period of 6 months. The control group (n=17) did not receive any intervention. Baseline and final examinations included dental parameters and concentrations of glycosylated hemoglobin (HbA1c) and high-sensitivity C-reactive protein (hsCRP). Results Physical activity showed a positive effect on periodontal health. Both the BOP (p= 0.005) and the severity of periodontitis (p= 0.001) were significantly reduced in the intervention group compared to the control group. Furthermore, HbA1c levels were reduced (p= 0.010) significantly in the intervention group while hsCRP levels significantly increased in the control group (p= 0.04). Conclusions Within the limitations of this randomized, controlled trial, physical activity over a period of 6 months is a health-promoting measure for patients with T2DM and improves both periodontal health and HbA1c concentrations.

BACKGROUND Lack of physical activity (PA) and sedentary behaviors are leading risk factors for non-communicable diseases (NCD). Web-based interventions are effective in increasing PA in older adults and in NCD patients. In many countries a course of spa therapy is commonly prescribed to NCD patients and represents an ideal context to initiating lifestyle changes. OBJECTIVE The main objective of this study was to evaluate in NCD patients the effectiveness of an intervention combining an individual face-to-face coaching during spa therapy and, when returning home, a web- and smartphone-based PA program including a connected wrist pedometer and a connected weighing scale, on the achievement of physical activity guidelines (PAG) 12 months after the end of spa therapy. METHODS This was a 12-month, prospective, parallel-group, randomized controlled trial. Patients were enrolled during spa therapy and randomized 1:1 to intervention or control group who received usual advices about PA. From the end of spa therapy, PA, weight, waist circumference, and quality of life of the participants in both groups, were assessed by phone every 2 months. Primary outcome was meeting PAG (PA≥600 METs) at 12 months after the end of spa therapy. Secondary outcomes were: meeting current PAG at 6 months of follow-up; sedentary time, weight and waist circumference, PA and quality of life, at 6 and 12 months. Objective use data of the web-and smartphone-based PA program were collected. Analytic methods include intention-to-treat and constrained longitudinal data analyses. RESULTS The study sample was 228 patients (female : 77.2% (176/228), mean age: 62.4 years (SD 6.7), retired: 53.9% (123/228), mean BMI = 28.2 kg.m-2 (SD 4.2)). No group differences were found for any baseline variable. At 12 months, the proportion of patients achieving PAG was significantly higher in intervention group versus control group (81% vs 67% respectively, OR = 2.34 (95% CI 1.02- 5.38; P=.045). No difference between intervention and control group was found neither in achieving PAG at 6 months nor for sedentary time, weight and waist circumference, at 6 and 12 months. Regarding quality of life, the physical component subscale score was significantly higher at 12 months in intervention group versus control group (mean difference: 4.1 (95% CI 1.9-6.3; P<.001). The mean duration use of the program was 7.1 months (SD 4.5). Attrition rate during the first 2 months of the program was 20.4% (23/113) whereas 39.8% (45/113) of the participants used the program for at least 10 months. CONCLUSIONS The results showed significantly more participants meeting PAG at one year in the intervention group compared to controls. A course of spa therapy offers the ideal time and setting to implement education in PA. Digital coaching seems to be more efficient than usual coaching for increasing the level of PA and decreasing sedentariness on the long term.

BACKGROUND To optimize postoperative outcomes after bariatric surgery, lifestyle changes including increased physical activity are needed. Micronutrient deficiency after surgery is also common and daily supplementation is recommended. OBJECTIVE The aim of the PromMera study is to evaluate the effects of a 12-week smartphone app intervention on promotion of physical activity (primary outcome) and adherence to postsurgery vitamin and mineral supplementation, as well as on other lifestyle factors and overall health in patients undergoing bariatric surgery. METHODS The PromMera study is a two-arm, randomized controlled trial comprising patients undergoing bariatric surgery. Participants are randomized postsurgery 1:1 to either the intervention group (ie, use of the PromMera app for 12 weeks) or the control group receiving only standard care. Clinical and lifestyle variables are assessed pre- and postsurgery after 18 weeks (postintervention assessment), 6 months, 1 year, and 2 years. Assessments include body composition using Tanita or BOD POD analyzers, muscle function using handgrip, biomarkers in blood, and an extensive questionnaire on lifestyle factors. Physical activity is objectively measured using the ActiGraph wGT3X-BT triaxial accelerometer. RESULTS A total of 154 participants have been enrolled in the study. The last study participant was recruited in May 2019. Data collection will be complete in May 2021. CONCLUSIONS Implementing lifestyle changes are crucial after bariatric surgery and new ways to reach patients and support such changes are needed. An app-based intervention is easily delivered at any time and can be a key factor in the adoption of healthier behavioral patterns in this rapidly growing group of patients.

BACKGROUND Excessive gestational weight gain (GWG) is a public health concern since it can lead to adverse consequences and health problems for expecting mothers and their unborn infants. There is a need to evaluate the effects of a GWG management intervention to reduce the burden and risk among overweight and obese women during pregnancy. OBJECTIVE To explore the efficacy of a mobile health (mHealth) intervention to prevent excessive GWG, overweight and obese pregnant women were invited to use an app and wearable activity tracker (WAT). METHODS A randomized controlled trial with an experimental study design. Ninety-two pregnant women were recruited, and all overweight and obese participants from the two prenatal outpatient clinics in northern Taiwan had, at less than 17 weeks gestation, a prepregnancy body mass index (BMI) ≥ 25 kg/m2. These participants were randomly assigned (1:1) by a random number table; the experimental group received an mHealth-based program using the MyHealthyWeight (MHW) app and a WAT to wear during pregnancy. The control group received standard antenatal treatments without any mHealth-based elements. Two hospital follow-up visits were scheduled at 24-26 weeks in the second trimester and 34-36 weeks in the third trimester. Sociodemographic characteristics, pregnancy physical activity questionnaire (PPAQ), a self-efficacy questionnaire and body weight were measures of interest. A generalized estimating equation (GEE) was used to examine the trajectories and the intervention effect on GWG. RESULTS No difference in GWG was found between the intervention and control groups at baseline. The weight gain trajectory in the entire cohort of women with obesity exhibited a quadratic pattern; compared with the control group, a slight increase in the intervention group was found in the second trimester. Throughout the whole pregnancy, the mHealth intervention group had a significantly lower proportion of excessive GWG in total and weekly weight gain. In particular, obese women in the intervention group, compared with obese women in the control group, gained less weight (average difference of 8.76 kg) in the third trimester. The GEE model indicated that obese women who were aged 35 years, had prepregnancy exercise habits, had perceived self-efficacy of diet, and had more physical activity had lower GWG (p<.05). CONCLUSIONS The mHealth program has shown positive results in significantly managing GWG among obese and overweight women. Among obese women, the second semester trajectory of weight gain and the lower proportion of excessive GWG were more notable than those of overweight women. Although the intervention seems to be more effective among women with obesity, our results show the potential to prevent excessive GWG during pregnancy in both overweight and obese women. Guidance may be provided to health-care professionals who wish to promote healthy diet and physical activity behaviors. CLINICALTRIAL The protocol of the study was registered in ClinicalTrials. gov (NCT04553731).

Recent animal studies found the potential of a collagen peptide derived from skate skin to have anti-obesity effects through the suppression of fat accumulation and regulation of lipid metabolism. However, no studies have yet been performed in humans. Here, this very first human randomized, placebo-controlled, and double-blinded study was designed to investigate the efficacy and tolerability of skate skin collagen peptides (SCP) for the reduction of body fat in overweight adults. Ninety healthy volunteers (17 men) aged 41.2 ± 10.4 years with a mean body mass index of 25.6 ± 1.9 kg/m2 were assigned to the intervention group (IG), which received 2000 mg of SCP per day or to the control group (CG) given the placebo for 12 weeks and 81 (90%) participants completed the study. Changes in body fat were evaluated using dual energy X-ray absorptiometry as a primary efficacy endpoint. After 12 weeks of the trial, the percentage of body fat and body fat mass (kg) in IG were found to be significantly better than those of subjects in CG (−1.2% vs. 2.7%, p = 0.024 and −1.2 kg vs. 0.3 kg, p = 0.025). Application of SCP was well tolerated and no notable adverse effect was reported from both groups. These results suggest the beneficial potential of SCP in the reduction of body fat in overweight adults.

1. The effects of varying levels of physical activity were tested in rats, starting at ages of 21, 32 and 55 days and continuing until go, 100, 125 and 205 days.2. Weight changes did not differ significantly between the exercise groups, except in the groups tested up to 205 days, when both the exercised group and the group with limited activity were significantly lighter than the control group.3. The weight of the soleus muscle was significantly greater in the exercised rats compared with controls and rats with limited activity, except in the oldest age-group. The weight of the tibialis anticus muscle did not differ significantly between the different exercise regimes.4. Heart weight was not significantly affected by the exercise regime, except that in rats studied from 55 to 125 days; the group with limited activity had significantly lighter hearts than those in the control group or the exercised group.5. The percentage body fat was lower in the exercised group compared with the limited activity group, and was less than the control group in both the rats studied up to 205 days and those studied from 21 to 90 days.6. Isoprenaline produced less cardiac damage in the exercised rats than in controls or in rats with limited activity. Animals who died following injection of isoprenaline had a higher percentage body fat than those animals with minimal cardiac damage.

Purpose: To evaluate the effectiveness of an individually tailored intervention for improvement in lifestyle behavior, health indicators, and prevention and reduction of overweight among construction workers. Design: Randomized controlled trial. Setting: Various blue-collar departments of a large construction company in the Netherlands. Participants: Blue-collar workers randomized to an intervention (n = 162) or a control group (n = 152). Intervention: The intervention group received individual coaching sessions, tailored information, and materials to improve lifestyle behavior during a 6-month period, and the control group received usual care. Measures: Body weight, body mass index (BMI), waist circumference, physical activity (PA) levels, dietary behavior, blood pressure, and blood cholesterol were assessed. Analysis: Effectiveness of the intervention on outcome measures at 6- and 12-month follow-up was assessed by using linear and logistic regression models adjusting for baseline levels. Results: After 6 months, a statistically significant intervention effect was found on body weight ( B = −1.06, P = .010), BMI ( B = −0.32, P = .010), and waist circumference ( B = −1.38, P = .032). At 6 months, the percentage of those meeting public health guidelines for PA increased significantly in the intervention group compared to the control group ( B = 2.06, P = .032), and for sugar-sweetened beverages, an intervention effect was found at 6 months as well ( B = −2.82, P = .003). At 12 months, for weight-related outcomes, these differences were slightly smaller and no longer statistically significant. The intervention was not effective on the total amount of moderate to vigorous PA and other dietary and health outcomes. Conclusion: Intervention participants showed positive changes in vigorous PA and intake of sugar-sweetened beverages compared to controls, as well as effects on weight-related outcomes at 6 months. Long-term effects were still promising but not statistically significant.

Background: Physical activity in the elderly is recommended by international guidelines to protect against cognitive decline and functional impairment. Objective: This Randomized Controlled Trial (RCT) was set up to verify whether medium-intensity physical activity in elderly people living in the community is effective in improving cognitive performance. Design: RCT with parallel and balanced large groups. Setting: Academic university hospital and Olympic gyms. Subjects: People aged 65 years old and older of both genders living at home holding a medical certificate for suitability in non-competitive physical activity. Methods: Participants were randomized to a 12-week, 3 sessions per week moderate physical activity program or to a control condition focused on cultural and recreational activities in groups of the same size and timing as the active intervention group. The active phase integrated a mixture of aerobic and anaerobic exercises, including drills of “life movements”, strength and balance. The primary outcome was: any change in Addenbrooke's Cognitive Examination Revised (ACE-R) and its subscales. Results: At the end of the trial, 52 people completed the active intervention, and 53 people completed the control condition. People in the active intervention improved on the ACE-R (ANOVA: F(1;102)=4.32, p=0.040), and also showed better performances on the memory (F(1;102)=5.40 p=0.022) and visual-space skills subscales of the ACE-R (F(1;102)=4.09 p=0.046). Conclusion: A moderate-intensity exercise administered for a relatively short period of 12 weeks is capable of improving cognitive performance in a sample of elderly people who live independently in their homes.
