Introduction: Tai Chi and walking are both moderate-intensity physical activity (PA) that can be easily practiced in daily life. The purpose of this study was to better understand that after practicing these two types of PAs in a relative short term and keeping the stable dietary intake in this period, how much body weight would be reduced and what extent the metabolic syndrome parameters would be improved; and if a significant weight loss was observed, whether this exercise-induced weight loss had adverse effect on bone mineral density (BMD). Methods: Three-hundred seventy-four healthy and physically inactive adults (45.8±5.3 years) from 9 geographic areas in Hong Kong were randomized to 12 weeks training (45 minutes per day, 5 days per week) of Tai Chi (n=124) or self-paced walking (n=121), or control group (n=129) at area level. Body weight, fat and lean mass, waist circumference, blood pressure and regional BMD, as well as the fasting blood samples were obtained at the beginning and end of trial. Fasting blood glucose (FBG), total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and triglycerides were analyzed. Results: On average, Tai Chi and walking groups lost 0.50 and 0.76 kg of body weight, 0.47 and 0.59 kg of fat mass, respectively (all p<0.001). No significant changes were observed for lean mass and BMD. Two intervention groups had significant improvements in waist circumference and FBG. The between-group difference of waist circumference and FBG was -3.7 cm and -0.18 mmol/L for Tai Chi vs. control; and -4.1 cm and -0.22 mmol/L for walking vs. control (all p<0.001). No significant differences were observed regarding blood pressure, total cholesterol, HDL-C, LDL-C and triglycerides compared to control (all p>0.05). The effects on all outcomes between Tai Chi and walking were similar (all p>0.05). Among intervention groups, change in lean mass, not fat mass or total weight loss, was significantly correlated to the change in BMD. Conclusions: 12-week Tai Chi and walking exercises can produce moderate weight loss and improve the waist circumference and FBG in middle-aged Hong Kong Chinese people, with no additional effects on BMD.

Tai Chi and walking are both moderate-intensity physical activity (PA) that can be easily practiced in daily life. The objective of the study was to determine the effects of these two PAs on weight loss, metabolic syndrome parameters, and bone mineral density (BMD) in Chinese adults. We randomized 374 middle-aged subjects (45.8 ± 5.3 years) into 12-week training (45 minutes per day, 5 days per week) of Tai Chi(n=124)or self-paced walking(n=121)or control group(n=129). On average, Tai Chi and walking groups lost 0.50 and 0.76 kg of body weight and 0.47 and 0.59 kg of fat mass after intervention, respectively. The between-group difference of waist circumference (WC) and fasting blood glucose (FBG) was −3.7 cm and −0.18 mmol/L for Tai Chi versus control and −4.1 cm and −0.22 mmol/L for walking versus control. No significant differences were observed regarding lean mass, blood pressure, triglycerides, total cholesterol, high-density and low-density lipoprotein cholesterol, and BMD compared to control. Change in lean mass, not fat mass or total weight loss, was significantly correlated to the change in BMD. Our results suggest that both of these two PAs can produce moderate weight loss and significantly improve the WC and FBG in Hong Kong Chinese adults, with no additional effects on BMD.

The Relationship

Background: The risk factors of metabolic syndrome (MetS) in menopausal women are potential causes of osteoporosis. However, there is no consensus on this. We aimed to determine the relationship between risk factors of MetS and bone mineral density (BMD) in menopausal Korean women. Methods: We enrolled 205 menopausal Korean women who visited a health promotion center in Seoul in 2015 and divided them into the following two groups according to the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) criteria with modified waist-circumference criteria: the non-MetS group (Group 1, n=90) and the MetS group (Group 2, n=115). Anthropometric parameters and clinical parameters, including blood pressure, blood lipid profile (cholesterol, triglycerides), and fasting blood sugar levels were recorded for all participants. BMD at the lumbar spine was determined using dual-energy X-ray absorptiometry (DEXA). The relationship between the risk factors of MetS and bone mineral density was analyzed by statistical methods. Results: There was no significant difference in risk factors of MetS between the groups. In correlation tests, waist circumference showed a significant association with body surface area (BSA) (r = -0.242, P < 0.001). Diastolic blood pressure was correlated with BSA (r = 0.186, P < 0.01) and bone mineral content (BMC) (r = 0.161, P < 0.05). However, multiple regression analysis showed no significant relationship between MetS risk factors and BMD. Conclusion: The risk factors of MetS did not affect BMD in menopausal Korean women. Follow-up studies with a larger study population are necessary size to allow the investigation of other research variables.

A randomized double-blind placebo controlled study design was used to assess the effects of flaxseed lignan complex supplementation during exercise training on a metabolic syndrome composite score and osteoporosis risk in older adults. A total of 100 subjects (≥50 years) were randomized to receive flaxseed lignan (543 mg·day–1 in a 4050 mg complex) or placebo while completing a 6 month walking program (30–60 min·day–1, 5–6 days·week–1). Fasting serum glucose, triacylglycerol (TAG), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein cholesterol, total cholesterol, interleukin-6, and tumor necrosis factor-α were measured every 2 months, while body composition, bone mineral density, and resting blood pressure were assessed at baseline and at 6 months. A composite Z score of 6 risk factors for metabolic syndrome (fasting glucose, HDL cholesterol, TAG, abdominal adiposity, blood pressure, and inflammatory cytokines) was calculated at baseline and at 6 months. Men taking placebo increased metabolic syndrome composite Z score (p < 0.05), but there were no changes in the other groups. A significant group × sex × time interaction was noted for TAG (p = 0.017) and diastolic blood pressure (p = 0.046), with men taking flaxseed lignan decreasing diastolic blood pressure relative to men taking placebo, and men taking placebo increasing TAG relative to men taking flax lignan. There were no differences between groups for change in bone measures, body composition, lipoproteins, or cytokines. Males taking the flaxseed lignan complex reduced metabolic syndrome score relative to men taking placebo, but a similar trend was not seen in females. Flaxseed lignan had no effect on bone mineral density or content, body composition, lipoproteins, glucose, or inflammation.

Background: A systematic review was performed to identify the types of physical activities effective as interventions in preventing metabolic syndrome in middle-aged women. Methods: Electronic databases (MEDLINE, EMBASE, the Cochrane Library, and CINAHL) served as the data sources. Cochrane’s Risk of Bias 2 was applied to assess the risk of bias of the randomized controlled trials. Meta-analyses were performed on selected studies using Review Manager 5.3. Thirty-one trials enrolling 2,202 participants were included. Results: Compared to controls, the effects of physical activity were indicated by pooled mean differences, which were −0.57 kg for body weight, −0.43 kg/m2 for body mass index, −1.63 cm for waist circumference, −4.89 mmHg for systolic blood pressure (BP), and −2.71 mmHg for diastolic BP. The effects were greater on the measurements of waist circumference and BP than on body weight and BMI. The types of physical activities were further analyzed according to sub-groups. Only aerobic exercise did not affect body weight and resistance exercise did not significantly change any results. Contrarily, combined exercises significantly reduced measurements of waist circumference and BP. Conclusion: This review can provide valuable information for research and implementation of measures to prevent metabolic syndrome in middle-aged women.

Abstract Objectives To determine if consuming four servings of white potatoes, processed potato products, or starchy carbohydrates for 16 weeks, as part of a higher protein diet, influence markers of cardiometabolic health in adults with metabolic syndrome. Methods Eleven adults with metabolic syndrome were randomly assigned to one of three higher protein diets incorporating different carbohydrate sources: 1) 4 servings of potatoes/week (P; n = 4; 4 female; 48.3 ± 9.4 y; 92.4 ± 9.6 kg; 36.3 ± 4.3 BMI); 2) processed potatoes (PP; n = 2; 1 female,1 male; 53.0 ± 15.0 y; 81.4 ± 17.0 kg; 29.6 ± 3.0 BMI); or 3) starchy carbohydrate (SC; n = 5; 4 female,1 male; 33.6 ± 5.0 y; 95.1 ± 18.2 kg; 35.3 ± 4.7 BMI). Data was collected at baseline, 4, 8,12, and 16 weeks. Glucose, cholesterol, and triglycerides were analyzed using a Cholestech LDX Analyzer. Height, weight, waist-to-hip ratio, blood pressure, mood, sleep quality, and grit were also measured. Body composition was measured using DEXA. Data were analyzed using Prism GraphPad version 8.0. Significance was set at P &lt; 0.05. Results There were no significant changes in body weight, BMI, waist-to-hip ratio, or body composition within or between each group. However, an increase in bone mineral density was observed within all groups(P &lt; 0.05). There was no effect of diet on plasma glucose and lipid levels. In addition, there was no change in blood pressure within each group. However, diastolic blood pressure decreased (P &lt; 0.05) in all groups. There were no changes in mood and grit. However, sleep quality improved within all groups (P &lt; 0.05). In addition, grip strength improved (P &lt; 0.05) within all groups. Conclusions The preliminary results of this study indicate that incorporating white potatoes, processed potatoes, or starch carbohydrates into a higher protein diet, does not influence markers of cardiometabolic health in adults with metabolic syndrome. Higher protein diets, may improve secondary outcomes such as sleep quality, bone mineral density, and grip strength. However, a larger study population is needed.

1068 randomly sampled adult Bangladeshi people were studied during a period of six months from October 2004 to March 2005. It was a randomized, prospective study. Cases that fulfilled two criteria of metabolic syndrome (MetS) were evaluated to see pattern and types of MetS. Out of 1068 patients, 110 (10.3%) fulfilled the inclusion criteria. 101 (9.4%) cases were labeled as metabolic syndrome according to NCEP ATP III criteria, 09 cases had only two criteria. 40 cases were male & 70 cases were female (M:F= 1:1.8). Mean age of patients with was 44.88, ranging from the age of 20-68 years. Majority (55%) of the patients were in the age group of 30-49 years. Half of the cases had BMI 30-34.9. Mean body weight of male was 85.9 kg and of female was 78.2 kg. Mean waist circumference of male was 41.7 inches and of female 40 inches. Mean HDL for male was 38.3 mg/dL and for female is 40.2 mg/dL. Mean Triglyceride for male was 172.1 and for female was 169.3 mg/dL. Mean total cholesterol for male was 216.7 and for female was 207.6 mg/dL. Mean systolic blood pressure (SBP) for men is 162 mm Hg & diastolic blood pressure (DBP) 99 mm Hg and for female mean SBP 155 and DBP 96 mm Hg. Metabolic syndrome is more prevalent in the 3rd and 4th decade of life in both sexes. It is almost twice common in female than male. Combination of hypertension, obesity & dyslipidemia comprises nearly 40% of its presentation.    doi: 10.3329/jom.v10i2.2813 J MEDICINE 2009; 10 : 48-51

Abstract Background Negatively charged very-low-density lipoprotein (VLDL-χ) in metabolic syndrome (MetS) patients exerts cytotoxic effects on endothelial cells and atrial myocytes. Atrial cardiomyopathy, manifested by atrial remodeling with a dilated diameter, contributes to atrial fibrillation pathogenesis and predicts atrial fibrillation development. The correlation of VLDL-χ with atrial remodeling is unknown. This study investigated the association between VLDL-χ and remodeling of left atrium. Methods Consecutively, 87 MetS and 80 non-MetS individuals between 23 and 74 years old (50.6% men) without overt cardiovascular diseases were included in the prospective cohort study. Blood samples were collected while fasting and postprandially (at 0.5, 1, 2, and 4 h after a unified meal). VLDL was isolated by ultracentrifugation; the percentile concentration of VLDL-χ (%) was determined by ultra-performance liquid chromatography. The correlations of left atrium diameter (LAD) with variables including VLDL-χ, LDL-C, HDL-C, triglycerides, glucose, and blood pressure, were analyzed by multiple linear regression models. A hierarchical linear model was conducted to test the independencies of each variable’s correlation with LAD. Results The mean LAD was 3.4 ± 0.5 cm in non-MetS subjects and 3.9 ± 0.5 cm in MetS patients (P < 0.01). None of the fasting lipid profiles were associated with LAD. VLDL-χ, BMI, waist circumference, hip circumference, and blood pressure were positively correlated with LAD (all P < 0.05) after adjustment for age and sex. Significant interactions between VLDL-χ and blood pressure, waist circumference, and hip circumference were observed. When adjusted for obesity- and blood pressure-related variables, 2-h postprandial VLDL-χ (mean 1.30 ± 0.61%) showed a positive correlation with LAD in MetS patients. Each 1% VLDL-χ increase was estimated to increase LAD by 0.23 cm. Conclusions Postprandial VLDL-χ is associated with atrial remodeling particularly in the MetS group. VLDL-χ is a novel biomarker and may be a therapeutic target for atrial cardiomyopathy in MetS patients. Trial registration ISRCTN 69295295. Retrospectively registered 9 June 2020.

Abstract Objectives Weight loss interventions for older adults often reduce bone mineral density (BMD), increasing risk of subsequent detrimental outcomes. This study explored the long-term impact of a higher protein diet plus exercise versus a diet plus exercise control treatment on body weight, bone mineral density at 3 sites, and fracture risk. Methods Obese (BMI 34.3 ± 4.7 kg/m2) older adults (n = 55; age = 70.0 ± 6.1 yrs) with Short Physical Performance Battery (SPPB) score = 9.2 ± 1.4 (out of 12) who completed a 6-month weight loss plus exercise trial were invited to return for assessment 12 months later. The original randomization was to either 0.8 g protein/kg body weight (Control) or 1.2 g protein/kg body weight, predominantly dairy (Protein). The 18-month assessment included BMD by DEXA (Hologic, Horizon model A) for femoral neck (FN), total hip (TH), and spine (lumbar vertebrae 1–4; LS), as well body weight and secondary outcomes for Fracture Risk Assessment Tool (FRAX). Results A total of 38 (69.1%) study completers were assessed at 18 mo. Body weight was lower than baseline for both Control and Protein (P &lt; 0.01), with Control (−4.8%) trending towards better maintenance of weight loss vs Protein (−2.3%) (P = 0.06). BMD at 18 mo. was not different from baseline in both Control and Protein for LS (0.01 ± 0.05 g/cm2 and −0.0002 ± 0.05 g/cm2; P = 0.512), FN (−0.01 ± 0.07 g/cm2 and −.009 ± 0.04 g/cm2; P = 0.814) and TH (−0.012 ± 0.03 g/cm2 and −.008 ± 0.033 g/cm2; P = 0.685). Change in BMD at 18 mo. did not differ by group at any site; the previously reported Protein group increase in LS at 6 mo. was not sustained. For individual fracture risk, between 0 and 18 mo., 6 improved (5 osteopenia to normal, 1 osteoporosis to osteopenia) and 1 worsened (normal to osteopenia but FRAX score below total and hip fracture thresholds). Conclusions The finding that obese older adults can maintain a lower body weight for 12 months without a decline in BMD and no increase in fracture risk amplifies our previous findings of legacy benefits of a short term obesity intervention for older adults. Further study is needed to determine if the protein benefit to LS is sustained if the higher protein intake is continued long term.

Aim: Metabolic syndrome (MS) is a significant public health problem and has the potential to increase the risk of developing cardiovascular diseases (CVD), the risk of type 2 Diabetes Mellitus (T2DM), the risk of stroke and the risk of a heart attack. MS has recently been considered an inflammatory disease. Lipoxins (LXs) are, on the other hand, bioactive lipid molecules synthesized from arachidonic acid (AA) and show potent anti-inflammatory and pro-resolving activities in vivo and in vitro conditions. In this study, we aimed to evaluate serum levels of LXA4 in MS patients and explore the relationship of serum LXA4 levels with MS components [waist circumference, blood pressure, serum high-density lipoprotein (HDL), and triglyceride (TG) levels]. Material and Method: In this study, the sample was composed of 39 patients diagnosed with MS and 32 healthy age- and sex-matched individuals. We measured serum LXA4 levels adopting the enzyme-linked immunosorbent assay (ELISA) method with “Human Lipoxin A4 ELISA Kit”. While collecting the blood samples from the subjects, we noted their ages, sex, physical examination findings, and anthropometric measurements [height, weight, waist circumference, and body mass index (BMI)]. Additionally, we obtained their serum TG, low-density lipoprotein (LDL), HDL, glucose, and cholesterol levels. Results: While we could not find any significant differences between the groups by age and sex (p>0.05), the groups significantly differed by weight, waist circumference, BMI, systolic blood pressure, diastolic blood pressure, TG, HDL, and FBG (p<0.05 for TG; p<0.001 for others). Moreover, serum levels of LXA4 significantly differed between the groups (p<0.05). Within-group comparisons showed that while serum levels of LXA4 significantly differed between male subjects (p=0.01), it was not the case for females (p>0.05). In both groups, there were negative correlations between serum LXA4 levels and waist circumference (r=-0.368 p=0.02). Yet, we found such an association only among male patients (r=-0.516 p=0.02). Conclusion: Overall, we found serum LXA4 levels to be significantly low in MS patients (p<0.05). Yet, it still needs to be elucidated whether this impairment is a cause or a result of MS. Finally, we discovered this impairment and its significant correlations with some MS parameters to be only in male patients, suggesting that serum LXA4 levels may vary by sex in MS patients.

Introduction: Workplace wellness programs offer opportunities for decreasing obesity in adults. The effectiveness of such programs varies and is influenced by key intervention components (e.g. duration, intensity, content). We developed a multicomponent workplace wellness program, MyWay to Health (MW2H), which was adapted from an evidence-based weight loss intervention with demonstrated efficacy and meets the 2013 Guideline for the Management of Overweight and Obesity in adults. The purpose of this one-group pretest-posttest study was to evaluate program acceptability and effectiveness of MW2H on primary and secondary outcomes. Hypotheses: We hypothesized that MW2H would result in 1) clinically meaningful weight loss of ≥5%, and 2) improvements in cardiometabolic indices. Methods: During weeks 1-26, participants met privately with an interventionist for up to 24 weekly, 40-minute sessions, receiving training in eating and physical activity behavior change, self-regulation, and socioenvironmental strategies. During weeks 27-52, participants received maintenance support through phone calls, email, or in-person visits. Our primary outcome was percent weight loss. Secondary outcomes included improvement in BMI, waist circumference, HbA1c, cholesterol, and blood pressure. Outcomes were compared at baseline and 26 weeks; body weight only was measured at 52 weeks. Wilcoxin Signed Rank Tests were used to examine outcomes. Results: Participants (N=154) were mostly female (85%), White (75%), had a median age of 50 (Interquartile Range (IQR): 17) years, a median baseline BMI of 34.7 (IQR: 8.8), a median household income of $70,000 (IQR: $50,000), and 54% had a college degree or higher. Median number of in-person sessions attended was 19 (IQR: 4.0). Percent weight loss at 26 weeks (median [IQR]: 7.5% [6.8%]) was clinically meaningful, with 71% of participants achieving ≥5% weight loss. Statistically significant improvements in BMI, waist circumference, HbA1c, HDL cholesterol, and systolic and diastolic blood pressure (p<0.001 for all) were observed. At week 52, body weight data were available for 106 (69%) participants. Median percent weight loss from baseline was 7.0% (IQR: 9.3%). Of participants who achieved ≥5% weight loss at week 26, 94% maintained this level of weight loss at week 52. Conclusions: The MW2H workplace wellness program was acceptable to participants, evidenced by high program attendance, and resulted in clinically meaningful and statistically significant improvements in body weight and cardiometabolic indices. A majority of participants achieved ≥5% weight loss by 26 weeks, and nearly all participants for whom data was available maintained this level of weight loss at week 52. Additional research is needed to optimize intervention components, identify factors that contribute to weight maintenance, and examine MW2H effectiveness in a more diverse population.
