Association of obesity with cardiovascular outcomes in patients with type 2 diabetes and cardiovascular disease: Insights from TECOS
2020
Obesity is a risk factor for type 2 diabetes (T2D) and cardiovascular disease (CVD). Whether obesity affects outcomes among those with T2D and atherosclerotic CVD (ASCVD) remains uncertain. Our objective was to investigate the relationship between body mass index (BMI) and ASCVD outcomes among TECOS participants with T2D and ASCVD.
BMI categories were defined as underweight/normal weight (BMI <25 kg/m2), overweight (25-29.9 kg/m2), obese class I (30-34.9 kg/m2), obese class II (35-39.9 kg/m2), and obese class III (≥ 40 kg/m2). Asian-specific BMI categories were applied to Asian participants. Kaplan-Meier survival analysis and Cox proportional hazards models were used to examine associations between baseline BMI and a composite CV outcome (CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for unstable angina).
For 14,534 TECOS patients with available BMI, mean age was 65.5 years; 29.3% were female, 32.0% non-White, and 23.1% insulin-treated, with median 3 years' follow-up. At baseline, 11.6% (n = 1686) were underweight/normal weight, 38.1% (n = 5532) overweight, 32.2% (n = 4683) obese class I, 12.4% (n = 1806) obese class II, and 5.7% (n = 827) obese class III. The composite CV outcome occurred in 11.4% (n = 1663) of participants; the outcome risk was lower, compared with under/normal weight, in overweight (HR 0.83, 95% CI 0.71-0.98) and obese class I (HR 0.79, 95% CI 0.67-0.93) individuals. Obesity was not associated with worse glycemic control.
The majority of TECOS participants with ASCVD and T2D were overweight or obese, yet overweight or obese class I individuals had lower CV risk than those who were under/normal weight. These results suggest the presence of an obesity paradox, but this paradox may reflect an epidemiological artifact rather than a true negative association between normal weight and clinical outcomes.

Background
Given the elevated prevalence and impact of overweight and the potential risk of non-communicable diseases among women of Somali background in high-income countries and recognising the potential positive impact of physical activity (PA) on these health conditions, it becomes imperative to focus on understanding the PA behaviour of this specific population. The objectives of this paper were twofold: firstly, to provide a comprehensive description of both objectively and subjectively measured PA level and sedentary time in a group of overweight women of Somali background in Norway, and secondly, to assess the effectiveness of a tailored, culturally sensitive, community-based intervention in increasing PA and reducing sedentary time.
Methods
169 overweight women of Somali background in Norway were randomised by borough to either a lifestyle programme or a comparison group. The programme consisted of two sessions per week for 12 weeks, combining classroom discussion with graded group-based PA led by coaches, followed by monthly sessions over nine months. PA was measured objectively using the ActivPAL monitor and subjectively using the international PA questionnaire short form (IPAQ-SF) at baseline and 12 months after baseline.
Results
The women took on average 6804 (SD = 3286) steps per day and were sedentary for 9.1 (SD = 3) hours per day at baseline. There were no differences between groups on any accelerometer measured PA variable at any timepoint. There were significant differences on vigorous intensity PA (25.9 min; 95% CI 7.7, 44.1) and total PA (77.6 min; 95% CI 13.2, 142.1) at the 12-month measurement session between the two groups using the IPAQ-SF.
Conclusion
Despite observing initially low PA levels and high sedentary time at baseline and thus a considerable potential for intervention, the intervention failed in attaining an increase in accelerometer measured PA or reduction in sedentary time compared to the control condition. However, self-reported measures indicated success in these aspects. The potential threats to the programme’s reliability and validity include high drop-out rates possible due to the COVID-19 pandemic, contamination and low attendance rates. These challenges underscore the complexity of interventions in this demographic, emphasising the need for further exploration and refinement of methodologies to effectively enhance PA levels and reduce sedentary time in immigrant women living in high-income countries.

Background/Objectives: Family meals have been shown to be an important protective factor for positive health outcomes. This study assessed the associations of parenting factors with family mealtime among overweight African American adolescents over a period of 4 months. It was hypothesized that increases in warm and responsive parenting (parental responsiveness, parental responsibility) would be associated with increased frequency and quality of family mealtimes, while more demanding and controlling parenting (parental demandingness, parental monitoring) would be associated with a reduced frequency and quality of family mealtimes over time. Methods: Data from baseline to 16 weeks were collected from 241 African American adolescent–parent dyads (adolescent: Mage = 12.8 ± 1.7 years; 64% female; MBMI%= 96.6 ± 4.2) that participated in the Families Improving Together (FIT) for Weight Loss randomized controlled trial. Results: Multilevel models revealed significant positive main effects of parental responsiveness and parental responsibility (p < 0.05) on the increased frequency of family meals (p < 0.01). Significant two-way interactions also showed that parental responsiveness (p < 0.05) predicted improved quality of family mealtimes, whereas parental demandingness (p < 0.01) predicted reduced quality of family mealtimes from baseline to 16 weeks. Conclusions: Results from this study have important implications for African American adolescent obesity prevention and future family-based intervention program guidelines.

Effect of lifestyle interventions of pregnant women on their dietary habits, lifestyle behaviors, and weight gain
2016
Background
Although it is known that lifestyle behaviors of pregnant women are closely related to maternal and fetal health, number of data concerning efficacy of intervention on lifestyle during pregnancy is limited. The purpose of this study is to determine the effect of lifestyle interventions on improving dietary habits and lifestyle behaviors, ensuring gestational weight gain (GWG) within recommended levels and limiting postpartum weight retention (PWR).
Methods
The study was conducted as a randomized controlled trial in a family health center located in Istanbul, Turkey, between June 2011 and July 2012. The primary outcomes were GWG, and the proportion of pregnant women whose GWG was within the Institute of Medicine (IOM) guidelines. One hundred two pregnant women with gestation ≤12 weeks, age ≥18 years, gravidity ≤2, and who did not intend to lose weight in prepregnancy period were randomly included in this study as intervention (
n
= 51) and control (
n
= 51) groups. The study was completed with 45 women for each group. The control group received routine antenatal care. The intervention group was received an individualized lifestyle intervention focusing on healthy lifestyle, diet, exercise, and weight monitoring as four sessions at 12–15, 16–18, 20–24, and 37 weeks gestation. Lifestyle behaviors were evaluated with Health-Promoting Lifestyle Profile-II. Dietary habits were assessed by 3-day dietary recalls, and weight was followed from pregnancy until 6 weeks postpartum.
Results
The lifestyle interventions had a significant effect on improving lifestyle behaviors, protein intake, percentage of energy from protein, calcium, magnesium, iron, zinc, and vegetable intakes when adjusted for confounders (
p
< 0.05). The proportion of women who were within the IOM recommendations was higher in the intervention group (51.1 %) than in the control group (28.9 %) The odds ratio for GWG within IOM was statistically significant between the groups (OR = 0.59, 95 % CI, 0.45–0.72). There were no difference between groups in terms of the other dietary intakes, total GWG, and PWR (
p
> 0.05).
Conclusions
Lifestyle intervention improves the lifestyle behaviors during pregnancy and increases the appropriate GWG for prepregnancy body mass index (BMI), but it has a limited effect in terms of improving dietary habits and has no effect on PWR.

This study aimed to evaluate dietary nutrient intake among Chinese pregnant women by comparison with Chinese Dietary Reference Intakes (DRIs) and to explore the association between dietary nutrients and preterm birth. A case‐control design was conducted in Beijing with 130 preterm delivery mothers in case group and 381 term delivery mothers in control group. Information on mothers’ diet was collected using a food frequency questionnaire, and nutrients and energy intakes were subsequently calculated based on DRIs. Multivariate analysis of variance was used to compare the differences between term and preterm groups in relation to dietary nutrients. Dietary nutrient intakes were imbalanced in both groups compared with Chinese DRIs. Preterm delivery mothers had a lower level of fat and vitamin E intake than term delivery mothers (p < 0.05). Multivariate analysis showed lower vitamin E intake in preterm delivery mothers with a prepregnancy BMI < 18.5 kg/m2 (p < 0.05) and higher carbohydrate intake in preterm delivery mothers with prepregnancy BMI ≥ 24 kg/m2 (p < 0.05). An imbalanced diet in both groups and low level of dietary intakes of fat and vitamin E in preterm group suggest health education measures should be taken to improve the dietary quality of pregnant women, especially for those with an abnormal prepregnancy BMI.

The GReat-Child™ Trial: A Quasi-Experimental Intervention on Whole Grains with Healthy Balanced Diet to Manage Childhood Obesity in Kuala Lumpur, Malaysia
2018
Background: The GReat-Child Trial was a quasi-experimental intervention that has emphasized whole grain as a strategy to manage childhood obesity. Methods: Two schools in Kuala Lumpur with similar demographic characteristics were assigned as intervention (IG) and control (CG). Eligibility criteria were overweight/obese children aged 9 to 11 years who had no serious co-morbidity. Children who reported consuming wholegrain foods in their 3-day diet-recall during screening were excluded. A total of 63 children (31 IG; 32 CG) completed the entire intervention program. The IG children underwent six 30-min nutrition education lessons and had school delivery of wholegrain food on a daily basis over a 12-week period. Parents of IG children attended 1-h individual diet counseling. Anthropometric outcomes including BMI-for-age z-score (BAZ), body fat percentage and waist circumference were measured at baseline [T0], post-intervention [T1] (3rd month) and follow-up [T2] (9th month). Results: IG showed significantly lower BAZ (weighted difference: −0.12; 95% CI: −0.21, −0.03; p = 0.009), body fat percentage (weighted difference: −2.6%; 95% CI: −3.7, −1.5; p < 0.001) and waist circumference (weighted difference: −2.4 cm; 95% CI: −3.8, −1.0; p = 0.001) compared to CG. IG reported significantly lower body fat percentage (weighted difference: −3.4%; 95% CI: 1.8, 5.0; p < 0.001) and waist circumference (weighted difference: −2.1 cm; 95% CI: −3.7, −0.5; p = 0.014) at T1 compared to T0. Conclusions: The GReat-Child Trial made a positive impact in managing childhood obesity. It can be incorporated into childhood obesity intervention programs that are being implemented by the policy makers.

Children’s learning about food is considerable during their formative years, with parental influence being pivotal. Research has focused predominantly on maternal influences, with little known about the relationships between fathers’ and children’s diets. Greater understanding of this relationship is necessary for the design of appropriate interventions. The aim of this study was to investigate the associations between the diets of fathers and their children and the moderating effects of fathers’ BMI, education and age on these associations. The diets of fathers and their first-born children (n 317) in the Melbourne Infant Feeding Activity and Nutrition Trial (InFANT) Program were assessed using an FFQ and 3×24-h recalls, respectively. The InFANT Program is a cluster-randomised controlled trial in the setting of first-time parents groups in Victoria, Australia. Associations between father and child fruit, vegetable, non-core food and non-core drink intakes were assessed using linear regression. The extent to which these associations were mediated by maternal intake was tested. Moderation of associations by paternal BMI, education and age was assessed. Positive associations were found between fathers’ and children’s intake of fruit, sweet snacks and take-away foods. Paternal BMI, education and age moderated the relationships found for the intakes of fruit (BMI), vegetables (age), savoury snacks (BMI and education) and take-away foods (BMI and education). Our findings suggest that associations exist at a young age and are moderated by paternal BMI, education and age. This study highlights the importance of fathers in modelling healthy diets for their children.

We investigated whether ethnic differences in handgrip strength, a marker of poor muscle strength and quality, is a potential cause of ethnic disparities in type 2 diabetes mellitus. We included 2086 Dutch, 2216 South Asian Surinamese, 2084 African Surinamese, 1786 Ghanaian, 2223 Turkish and 2199 Moroccan origin participants from the HELIUS study. We analyzed ethnic differences in handgrip strength, and its association with type 2 diabetes mellitus using logistic regression analyses adjusted for socio-demographic factors, body composition and lifestyle factors. Additionally, we investigated whether handgrip strength explained the ethnic differences in type 2 diabetes mellitus. We found that handgrip strength differed significantly across ethnic groups. After full adjustment, we found an inverse association with type 2 diabetes mellitus (OR 0.95; 95% CI 0.92-0.97) that did not differ substantially between ethnic groups, men and among women, and lean and overweight individuals. The association was not affected by the measure used to define type 2 diabetes mellitus, but was attenuated by exclusion of people with known diabetes. The ethnic differences in type 2 diabetes mellitus were not explained by handgrip strength (e.g. the OR for the South Asian Surinamese vs. Dutch changed from 5.03; 3.69-6.68 to 4.87; 3.57-6.65). In conclusion, we found large ethnic differences in handgrip strength and a consistent association of low handgrip strength with prevalent type 2 diabetes mellitus. This suggests that handgrip strength may be investigated as a target for intervention or a marker to identify people at risk of type 2 diabetes mellitus.

IntroductionMaternal overweight or obesity has been associated with metabolic syndrome through 1 year postpartum, but it remains unknown whether a culturally-modified, motivationally-targeted, and individually-tailored Lifestyle Intervention could improve postpartum cardiometabolic health among Hispanic women with overweight or obesity.MethodsProyecto Mamá was a randomized controlled trial conducted in Western Massachusetts from 2014 to 2020 in which Hispanic women with overweight/obesity were randomized to a Lifestyle Intervention (LI) involving diet and exercise or to a comparison Health and Wellness Intervention (HW). Biomarkers of cardiovascular risk (i.e., lipids, C-reactive protein) and insulin resistance (fasting insulin, glucose, HbA1c, homeostasis model assessment [HOMA-IR], leptin, adiponectin) were measured at baseline (early pregnancy), mid-pregnancy, and 6 weeks, 6 months, and 12 months postpartum. Generalized linear mixed effect models were used to evaluate differences in the change in biomarkers over the course of postpartum follow-up time.ResultsIn intent-to-treat analyses among eligible women (LI; n=51, HW; n=58) there were no significant differences in changes in biomarkers of CVD risk or insulin resistance over the postpartum year; for example, the intervention effect for total cholesterol was 6.98 (SE: 6.36, p=0.27) and for HbA1c was −0.01 (SE: 0.4, p=0.85). In pooled analyses, regardless of intervention arm, women who participated in any vigorous activity had less of an increase in HbA1c (intervention effect = −0.17, SE: 0.05, p=0.002) compared to those with no vigorous activity, and similarly beneficial associations with other cardiovascular risk biomarkers (p<0.05).DiscussionWomen who participated in vigorous activity, regardless of their assigned intervention arm, had more favorable changes in biomarkers of insulin resistance.SignificanceWomen with overweight/obesity during pregnancy are at an increased risk of adverse cardiometabolic profiles and future development of type 2 diabetes and cardiovascular disease. Hispanic women are disproportionately affected by cardiometabolic disorders but have largely been excluded from lifestyle intervention studies. Although providing a lifestyle intervention to Hispanic women with overweight/obesity resulted in no significant differences in postpartum cardiometabolic biomarkers, women who articipated in vigorous activity, regardless of their assigned intervention arm, had favorable changes in insulin resistance biomarkers. These findings suggest that the intensity of physical activity may be important for improving postpartum cardiometabolic biomarkers among high-risk, Hispanic women.

Compounding effects of stress on diet, physical activity, and wellbeing among African American parents: a qualitative study to inform the LEADS health promotion trial
2024
The purpose of the study was to conduct in-depth qualitative interviews to understand the lived experiences of African American parents of overweight adolescents who had previously participated in a family-based weight loss program and to utilize these insights to inform the essential elements of the LEADS trial, an integrated resilience stress management and health promotion intervention. Participants (N = 30) were African American parents and/or caregivers (96.7% female; Mage = 49.73, SD = 10.88; MBMI = 37.63, SD = 8.21) of adolescents with overweight and/or obesity. Interviews were transcribed and coded using inductive and deductive approaches for themes by two independent coders. Inter-rater reliability was acceptable (r = 0.70–0.80) and discrepancies were resolved to 100% agreement. Prominent stress themes included caregiver responsibilities, work, interpersonal family conflict, and physical and emotional consequences of chronic stress. Participants also noted decreases in physical activity and poor food choices due to stress. Coping mechanisms included prayer/meditation, church social support, and talking with family/partner. Results highlight the importance of mitigating stress among African American parents through stress management and cultural/familial resilience approaches to increase the likelihood of engagement in behavioral strategies in health promotion programs. Future studies should assess the utility of incorporating stress management components and health promotion techniques to improve health outcomes among African American families.
