Effect of Decaffeinated Green Tea Polyphenols on Body Fat and Precocious Puberty in Obese Girls: A Randomized Controlled Trial.

Background: Obesity has been reported to be an important contributing factor for precocious puberty, especially in girls. The effect of green tea polyphenols on weight reduction in adult population has been shown, but few related studies have been conducted in children. This study was performed to examine the effectiveness and safety of decaffeinated green tea polyphenols (DGTP) on ameliorating obesity and early sexual development in girls with obesity. Design: This is a double-blinded randomized controlled trial. Girls with obesity aged 6-10 years old were randomly assigned to receive 400 mg/day DGTP or isodose placebo orally for 12 weeks. During this period, all participants received the same instruction on diet and exercise from trained dietitians. Anthropometric measurements, secondary sexual characteristics, B-scan ultrasonography of uterus, ovaries and breast tissues, and related biochemical parameters were examined and assessed pre- and post-treatment. Results: Between August 2018 and January 2020, 62 girls with obesity (DGTP group n = 31, control group n = 31) completed the intervention and were included in analysis. After the intervention, body mass index, waist circumference, and waist-to-hip ratio significantly decreased in both groups, but the percentage of body fat (PBF), serum uric acid (UA), and the volumes of ovaries decreased significantly only within the DGTP group. After controlling confounders, DGTP showed a significantly decreased effect on the change of PBF (ß = 2.932, 95% CI: 0.214 to 5.650), serum UA (ß = 52.601, 95% CI: 2.520 to 102.681), and ovarian volumes (right: ß = 1.881, 95% CI: 0.062 to 3.699, left: ß = 0.971, 95% CI: 0.019 to 1.923) in girls with obesity. No side effect was reported in both groups during the whole period. Conclusion: DGTP have shown beneficial effects of ameliorated obesity and postponed early sexual development in girls with obesity without any adverse effects.

Relationship Between Modified Body Adiposity Index and A Body Shape Index with Biochemical Parameters in Bariatric Surgery Candidates.

BACKGROUND: Body mass index, an estimate of body fat percentage, has been previously shown to be associated with metabolic disorders. However, there is little data on the associations between a body shape index (ABSI) or modified body adiposity index (MBAI), which provide valuable definitions of body fat, with serum biochemical parameter levels. Therefore, this study was conducted to find either ABSI or MBAI associations with serum biochemical parameter levels in bariatric surgery candidates. METHODS: This cross-sectional study was conducted on 776 bariatric surgery candidates (age range 18-69 years) between November 2010 and September 2017. Demographic data, anthropometric indices, biochemical parameters, and body composition analysis data were drawn from the National Obesity Surgery Database, Iran. ABSI and MBAI were calculated using related equations. A stepwise multivariate linear regression was used to evaluate whether ABSI or MBAI was associated with each serum biochemical parameter. RESULTS: ABSI, age, and multivitamin/mineral supplementation (MVMS) were independently associated with serum vitamin D (ß = 24.374, SE 10.756, P value 0.026; ß = 0.022, SE 0.007, P value 0.002; ß = 0.639, SE 0.235, P value 0.008). However, a negative association was observed between MBAI and vitamin D (ß = - 0.037, SE 0.016, P value 0.025) in a model adjusted for age and MVMS. Additionally, MBAI and age showed a significant positive association with serum HDL-c (ß = 0.185, SE 0.085, P value 0.028; ß = 0.171, SE 0.033, P value < 0.001), although there was a negative association between male sex and HDL-c (ß = - 4.004, SE 0.891, P value < 0.001). CONCLUSION: ABSI and MBAI may be appropriate indices in predicting serum vitamin D and HDL-c levels.

Effect of Healing Meditation on Weight Loss and Waist Circumference of Overweight and Obese Women: Randomized Blinded Clinical Trial.

Objective: To evaluate the effect of healing meditation on weight loss and waist circumference for women undergoing a standard weight loss treatment. Design: We conducted a randomized, parallel-controlled, blinded clinical trial. Randomization was stratified by body mass index category and based on blocks of four. Setting: An outpatient clinic in Brazil. Subjects: Women with overweight and obesity. Intervention: For 8 weeks, in addition to the standard weight loss treatment, the intervention group underwent a healing meditation program, and the control group participated in a two round table just to observe the treatment compliance. Outcome measures: The primary outcome was the percentage of weight loss, blindly assessed regarding the allocation group. Results: Of 121 women interested in participating in the study, 55 were included and randomized, 27 for the intervention group and 28 for the control group. Baseline characteristics were similar between groups. After 8 weeks, the intervention group had the highest relative reduction to initial body weight (-2.9% [interquartile range {IQR} -4.4 to -1.6] vs. -0.7% [IQR -1.1 to -5.0], p < 0.001). Waist circumference outcome was also significantly reduced in the intervention group (5 cm [IQR -6.0 to 4.0] vs. -1 cm [IQR -2.0 to 0.0], p < 0.001). The result of the intervention group was maintained until the 16th week. Between 8th and 16th week, the control group underwent meditation and presented significant weight reduction (-1.95 kg [IQR -3.2 to -1.1], p < 0.001 and -2.3% [IQR -4.1 to -1.3], p < 0.001), showing similar effect to the intervention group (p = 0.428). Conclusion: The addition of healing meditation to the standard weight loss treatment may reduce weight and waist circumference over a short period in overweight or obese women.

Cannabis consumption and non-alcoholic fatty liver disease. A three years longitudinal study in first episode non-affective psychosis patients.

INTRODUCTION: Increased incidence of obesity and excess weight lead to an increased incidence of non-alcoholic fatty liver disease (NAFLD). Recent evidence indicates a protective effect of cannabis consumption on weight gain and related metabolic alterations in psychosis patients. Overall, patients are at greater risk of presenting fatty diseases, such as NAFLD, partly due to lipid and glycemic metabolic disturbances. However, there are no previous studies on the likely effect of cannabis on liver steatosis. We aimed to explore if cannabis consumption had an effect on hepatic steatosis, in a sample of first-episode (FEP) non-affective psychosis. MATERIAL AND METHODS: A total of 390 patients were evaluated at baseline and after 3 years of initiating the antipsychotic treatment. Anthropometric measurements and liver, lipid, and glycemic parameters were obtained at both time points. All but 6.7% of patients were drug-naïve at entry, and they self-reported their cannabis use at both time points. Liver steatosis and fibrosis were evaluated through validated clinical scores (Fatty Liver Index [FLI], Fibrosis-4 [FIB-4], and NAFLD). RESULTS: At 3-year follow-up, cannabis users presented significantly lower FLI scores than non-users (F = 13.874; p < .001). Moreover, cannabis users less frequently met the criteria for liver steatosis than non-users (X2 = 7.97, p = .019). Longitudinally, patients maintaining cannabis consumption after 3 years presented the smallest increment in FLI over time, which was significantly smaller than the increment in FLI presented by discontinuers (p = .022) and never-users (p = .016). No differences were seen in fibrosis scores associated with cannabis. CONCLUSIONS: Cannabis consumption may produce a protective effect against liver steatosis in psychosis, probably through the modulation of antipsychotic-induced weight gain.

Demographic, health behavior, and cardiometabolic risk factor profile in yoga and non-yoga participants: NHANES 1999-2006.

OBJECTIVE: To examine and compare the demographic, health behavior, and cardiometabolic risk factor characteristics of participants who report 1) participating in yoga, 2) not participating yoga, or 3) are inactive, using a nationally representative sample of U.S. adults. DESIGN: Study participants were from the 1999-2006 National Health and Nutrition Examination Survey (NHANES) who self-reported participation in yoga (n = 74), no-yoga (n = 3,753) or were inactive (n = 1,285). Participants in the no-yoga group did engage in other types of physical activity, while the inactive group reported no activity during the survey period. RESULTS: Yoga participants were primarily female (80.7%), college educated (51.9%), mostly non-smokers (46.9%), and reported moderate alcohol consumption (72.1%). Yoga participants were found to be significantly less likely to have an elevated waist circumference (OR = 0.40, p < 0.01; OR = 0.30, p < 0.01), and a low HDL (OR = 0.43, p = 0.03; OR = 0.34, p < 0.05) compared to both non-yoga participants and inactive individuals, respectively. Yoga participants were 61% less likely to have elevated blood glucose compared to non-yoga participants (OR = 0.39, p < 0.05). Compared to inactive individuals, yoga participants were 52% (OR = 0.48, p < 0.05) and 66% (OR = 0.34, p < 0.05) less likely have an elevated body mass index and have elevated triglyceride levels, respectively. CONCLUSIONS: Given the emergence of yoga as a common form of physical activity, it is imperative to understand the characteristics of those who participate in yoga to further understand its relationship with cardiovascular risk. This study was one of the first to use nationally-representative data and objectively measured cardiometabolic variables. Key Words: complementary medicine, epidemiology, survey, population, physical activity, cardiovascular disease.

Oral Glutamine Supplementation Reduces Obesity, Pro-Inflammatory Markers, and Improves Insulin Sensitivity in DIO Wistar Rats and Reduces Waist Circumference in Overweight and Obese Humans.

In the present study, we aimed to investigate whether chronic oral glutamine (Gln) supplementation may alter metabolic parameters and the inflammatory profile in overweight and obese humans as well as whether Gln may modulate molecular pathways in key tissues linked to the insulin action in rats. Thirty-nine overweight/obese volunteers received 30 g of Gln or alanine (Ala-control) for 14 days. Body weight (BW), waist circumference (WC), hormones, and pro-inflammatory markers were evaluated. To investigate molecular mechanisms, Gln or Ala was given to Wistar rats on a high-fat diet (HFD), and metabolic parameters, euglycemic hyperinsulinemic clamp with tracers, and Western blot were done. Gln reduced WC and serum lipopolysaccharide (LPS) in overweight volunteers. In the obese group, Gln diminished WC and serum insulin. There was a positive correlation between the reduction on WC and LPS. In rats on HFD, Gln reduced adiposity, improved insulin action and signaling, and reversed both defects in glucose metabolism in the liver and muscle. Gln supplementation increased muscle glucose uptake and reversed the increased hepatic glucose production, in parallel with a reduced glucose uptake in adipose tissue. This insulin resistance in AT was accompanied by enhanced IRS1 O-linked-glycosamine association in this tissue, but not in the liver and muscle. These data suggest that Gln supplementation leads to insulin resistance specifically in adipose tissue via the hexosamine pathway and reduces adipose mass, which is associated with improvement in the systemic insulin action. Thus, further investigation with Gln supplementation should be performed for longer periods in humans before prescribing as a beneficial therapeutic approach for individuals who are overweight and obese.

Effect of Regular Exercise and Functional Beverages on Changes in Body Weight and Waist Circumference in Healthy Japanese Subjects.

Background and objectives: The effects on anthropometry of several lipid-related foods for specified health uses (FOSHU) approved in Japan are not well known. We examined the effects of regular exercise and lipid-related FOSHU beverages on changes in body weight (BW) and waist circumference (WC) among factory and office workers. Materials and Methods: A total of 3002 subjects aged 20 years or older (2497 men and 505 women) received health check-ups in 2015 and 2016 and completed a lifestyle questionnaire. The association between regular exercise or lipid-related FOSHU beverage intake and changes in BW or WC were evaluated using trend test and linear regression analysis. Results: Regular exercise (≥1/week) was reported by 774 subjects (25.8%), and regular consumption of lipid-related FOSHU beverages (≥1/week) was reported by 1168 subjects (38.9%). The significant association between lipid-related FOSHU beverage intake and changes in BW was only observed among subjects with regular exercise (p for trend = 0.042). In the multivariable analysis, sex, older age, baseline weight, baseline body mass index (BMI), and regular exercise behavior were significantly associated with smaller changes in BW (p < 0.05). In WC, only the baseline values of WC and BMI were associated with one-year changes of WC. Conclusions: The combination of regular exercise and lipid-related FOSHU may be effective in maintaining BW.

Prenatal n-3 long-chain fatty acid status and offspring metabolic health in early and mid-childhood: results from Project Viva.

Higher maternal and biomarker levels of n-3 long-chain polyunsaturated fatty acids (LCPUFAs) have been associated with improved perinatal outcomes and may also influence offspring metabolic health. Past studies were not powered to examine metabolic outcomes and few have specifically targeted metabolically vulnerable populations. We examined the associations of prenatal n-3 LCPUFA status with markers of metabolic health in early and mid-childhood in the full population as well as stratified by maternal glucose tolerance. Our data consisted of 1418 mother-child dyads from Project Viva, a longitudinal, prospective pre-birth cohort enrolled in eastern Massachusetts. We assessed maternal dietary intake of fish and n-3 LCPUFA in mid-pregnancy using a validated food frequency questionnaire. N-3 LCPUFA levels were quantified in maternal second trimester and umbilical cord plasma using liquid-gas chromatography. We assessed offspring anthropometry, adiposity, and blood pressure at early (median age: 3.2 years) and mid-childhood (median age: 7.7 years); and assayed blood samples collected at these visits for metabolic biomarkers. We report here multivariable effect estimates and 95% CI. Early childhood BMI z-score was on average 0.46 (1.03) units and waist circumference 51.3 (3.7) cm. At mid-childhood these measures were 0.39 (1.00) units and 60.0 (8.3) cm, respectively. Higher cord plasma DHA levels were associated with lower BMI z-score ((Q)uartile 4 vs. Q1: -0.21, 95% CI: -0.38, -0.03), waist circumference (Q4 vs. Q1: -0.63, 95% CI: -1.27, 0.00 cm), and leptin levels (Q4 vs. Q1: -0.36, 95% CI: -0.77, 0.05 ng/mL) in early childhood. These associations were strongest and reached significance in offspring of women with isolated hyperglycemia vs. better or worse glycemic status. Higher maternal DHA + EPA (Q4 vs. Q1: -1.59, 95% CI: -2.80, -0.38 µg/mL) and fish (≥3 vs. 0 portions/week: -2.18, 95% CI: -3.90, -0.47 µg/mL) intake was related to lower adiponectin in early childhood. None of these associations persisted with mid-childhood outcomes. We did not find associations with any of the other outcomes. This study supports early and possibly transient effects of prenatal n-3 LCPUFA status on anthropometric measures and adipokine levels. It also raises the possibility that offspring of women with isolated hyperglycemia derive the most benefits from higher n-3 LCPUFA status.

Effect of Conjugated Linoleic Acid as a Supplement or Enrichment in Foods on Blood Glucose and Waist Circumference in Humans: A Metaanalysis.

BACKGROUND: Controversy persists regarding the effect of mixtures of conjugated linoleic acids (c9, t11- and t10, c12-CLA) in fasting blood glucose (FBG) and waist circumference (WC) in humans. OBJECTIVE: The aim of this meta-analysis is to explore the effect of CLA on FBG and WC. METHOD: PubMed, Google Scholar, Cochrane Library, Science Direct, Pro-Quest and Ovid were searched up to January 2015. Studies that examined the effect of CLA supplementation or foods enriched with CLA on FBG and WC in healthy adults were included. Studies in animals or unhealthy individuals and studies other than clinical trials were excluded. Of the 3,095 articles initially retrieved, 32 eligible randomized clinical trials were included in this systematic review. The mean difference and standard deviation of changes in FBG and WC in the intervention and control groups were used as effect size measures for the meta-analysis. RESULTS: Subgroup analysis showed that CLA supplement consumption did not significantly influence FBG (standardized mean differences [SMD] = 0.075 mg/dL; 95% confidence interval (CI) = -0.099 to 0.249; p = 0.399) or WC (SMD = -0.149 cm; 95% CI = -0.522 to 0.225; p = 0.435). Foods enriched in CLA also showed no significant effect on FBG (SMD = 0.126 mg/dL; 95% CI = -0.100 to 0.352; p = 0.274) or WC (SMD = -0.233 cm; 95% CI = -0.625 to 0.159; p = 0.244). CONCLUSION: We conclude that c9, t11- and t10, c12-CLA administered as a supplement or used to enrich foods does not affect FBG or WC in humans.

Adiponectin Potentially Contributes to the Antidepressive Effects of Baduanjin Qigong Exercise in Women With Chronic Fatigue Syndrome-Like Illness.

Our recent study demonstrates that adiponectin signaling plays a significant role in mediating physical exercise-exerted effects on hippocampal neurogenesis and antidepression in mice. Whether the findings can be translated to humans remains unknown. This study aimed to investigate the effects of Baduanjin Qigong exercise on adiponectin and to evaluate whether adiponectin is involved in the antidepressive effects of Qigong exercise on chronic fatigue syndrome (CFS)-like illness. This is a randomized, waitlist-controlled trial. One hundred eight female participants were randomly assigned to either Qigong exercise or waitlist groups. Sixteen 1.5-h Qigong lessons were conducted. Outcome measures were taken at three time points. Baseline adiponectin levels were negatively associated with body weight, body mass index, waist circumference, hip circumference, and waist/hip ratio in women with CFS-like illness. Compared with the waitlist control, Qigong exercise significantly reduced anxiety and depression symptoms and significantly raised plasma adiponectin levels (median = 0.8 vs. -0.1, p < 0.05). More interestingly, increases in adiponectin levels following Qigong exercise were associated with decreases in depression scores for the Qigong group (r = -0.38, p = 0.04). Moreover, adjusted linear regression analysis further identified Qigong exercise and change in adiponectin levels as the significant factors accounting for reduction of depression symptoms. Baduanjin Qigong significantly increased adiponectin levels in females with CFS-like illness. Decreases in depression symptoms were associated with increases in adiponectin levels following Qigong exercise, indicating that the potential contribution of adiponectin to Qigong exercise elicited antidepressive effects in human subjects.

Impulsivity is associated with blood pressure and waist circumference among adolescents with bipolar disorder.

OBJECTIVE: Cardiovascular risk factors (CVRFs) and impulsivity are common in bipolar disorder (BD), and CVRFs are also linked with impulsivity through a number of mechanisms, both behavioral and biological. This study examines the association between CVRFs and impulsivity in adolescents with BD. METHODS: Subjects were 34 adolescents with BD and 35 healthy control (HC) adolescents. CVRFs were based on International Diabetes Federation metabolic syndrome criteria (triglycerides, high-density lipoprotein cholesterol, waist circumference, blood pressure (BP) and glucose). Impulsivity was measured using the computerized Cambridge Gambling Task (CGT). Analyses controlled for age, IQ, lifetime attention deficit hyperactivity disorder, and current antipsychotic use. RESULTS: Adolescents with BD had higher diastolic BP (73.36 ± 9.57 mmHg vs. 67.91 ± 8.74 mmHg, U = 401.0, p = 0.03), higher triglycerides (1.13 ± 0.60 mmol/L vs. 0.78 ± 0.38 mmol/L, U = 373.5, p = 0.008), and were more likely to meet high-risk criteria for waist circumference (17.6% vs. 2.9%, p = 0.04) vs. HC. Within the BD group, CGT sub-scores were correlated with CVRFs. For example, overall proportion bet was positively correlated with systolic (r = 0.387, p = 0.026) and diastolic (ρ = 0.404, p = 0.020) BP. Quality of decision-making was negatively correlated with systolic BP (ρ = -0.401, p = 0.021) and waist circumference (ρ = -0.534, p = 0.003). Significant interactions were observed, such that BD diagnosis moderates the relationship between both waist circumference and BP with CGT sub-scores. CONCLUSION: BP and waist circumference are associated with impulsivity in BD adolescents, but not in HC adolescents. Future studies are warranted to determine temporality and to evaluate whether optimizing CVRFs improves impulsivity among BD adolescents.

Overall and abdominal adiposity in midlife and subsequent cognitive function.

OBJECTIVES: The scientific literature supports a link between midlife adiposity and cognitive function or decline but most studies to-date have investigated only overall adiposity, often omitting important confounders from the analyses. We investigated in a cross-time design the relationships between two different midlife adiposity markers and subsequent cognitive function, testing midlife dietary patterns as a potential confounder of the associations. DESIGN: The study was based on the «Supplémentation en Vitamines et Minéraux Antioxydants¼ randomized trial (SU.VI.MAX, 1994-2002) and the SU.VI.MAX 2 observational follow-up study (2007-2009). SETTING: A general-population cohort in France. PARTICIPANTS: N=2,817 individuals (1,493 men and 1,324 women) included in both the SU.VI.MAX and SU.VI.MAX 2 studies. MEASUREMENTS: The cognitive performance of 2,817 middle-aged adults participating in the SU.VI.MAX (Supplémentation en Vitamines et Minéraux Antioxydant) study was assessed in 2007-2009 using 6 neuropsychological tests. Principal component analysis was used to derive specific cognitive scores. A composite cognitive score was also computed. Body mass index (BMI) and waist circumference (WC) were measured 13 years earlier (1994). Associations between midlife adiposity and cognitive functioning were estimated through covariance analyses. RESULTS: After adjustment for obesity-related cardio-metabolic parameters, higher BMI and larger WC at midlife predicted lower executive function. For example, the adjusted mean difference (95% confidence interval) for 1 SD increase in WC was -0.48 (-0.97, 0.00). Obese participants in midlife showed an adjusted mean difference (95% confidence interval) of -1.68 (-3.15, -0.22) compared with non-obese. Further adjustment for midlife dietary patterns slightly attenuated these associations. No relationships were observed with verbal memory or global cognitive function. CONCLUSION: Midlife overall and abdominal adiposity were similarly associated with lower executive functioning scores. Dietary patterns may partly explain such a relationship, arguing for the importance of controlling for lifestyle confounders in future studies.

Beanblock® (standardized dry extract of Phaseolus vulgaris) in mildly overweight subjects: a pilot study.

OBJECTIVE: This study evaluates the efficacy of Beanblock®, a standardized extract of Phaseolus vulgaris L., on weight control in healthy overweight subjects on a weight management plan that combined lifestyle and dietary advice. PATIENTS AND METHODS: Sixty overweight (BMI 25-30 kg/m2) healthy subjects were enroled. All subjects were instructed to follow a weight management plan, accompanied by dietary advice. Thirty subjects used Beanblock® for at least 12 weeks (50 mg tablets, two times daily). The remaining 30 subjects did not receive any supplementation (management-only). The main endpoints were changes in body weight and waist circumference, with plasmatic oxidative stress, satiey and appetite being also evaluated. RESULTS: At week 12, the supplementation with Beanblock® was associated with a reduction in body weight (from 82.8 ± 9.1 kg to 78.8 ± 8.9 kg; p < 0.0001) and a decrease of waist circumference from 94.4 ± 10.3 cm to 88.2 ± 10.0 cm (p < 0.0001). Conversely, only marginal changes were observed in the control group. Oxidative stress was also significantly decreased with Beanblock® (from 380.4 ± 14.8 to 340.7 ± 14.8 Carr Units; p < 0.0001). Satiety and appetite improved in the supplement group. No side effects were observed and compliance was optimal. CONCLUSIONS: Beanblock®, in association with a health management plan, was useful for weight control in mildly overweight healthy subjects.

An appropriate diet and aerobic physical activity are effective in overweight management. In studies, Glucerna helped decrease the body weight and waist circumference in obesity and diabetes mellitus.

Association of a reduction in central obesity and phosphorus intake with changes in urinary albumin excretion: the PREMIER study.

BACKGROUND: Excess adiposity and dietary factors may be important determinants of urinary albumin excretion (UAE). STUDY DESIGN: Observational analysis of PREMIER, a randomized trial designed to lower blood pressure using behavioral interventions (counseling on weight loss, healthy diet, and exercise). SETTING & PARTICIPANTS: 481 participants with normal kidney function who provided adequate 24-hour urine collections at baseline and 6 months. PREDICTORS: Change in waist circumference; 24-hour urine sodium, potassium, and phosphorus excretion; and protein intake estimated from urea nitrogen. OUTCOMES & MEASUREMENTS: The primary outcome was change in log-transformed 24-hour UAE over 6 months. RESULTS: After 6 months, the proportion of individuals with UAE ≥10 mg/d decreased from 18.7% to 12.7% (P < 0.001). Changes in mean waist circumference (-4.2 ± 6.6 [SD] cm), 24-hour excretion of sodium (-28.2 ± 71.7 mmol/d), potassium (+8.4 ± 27.8 mmol/d), phosphorus (-27.7 ± 314.1 mg/d), and protein intake (-1.7 ± 19.4 g/d) were observed. After adjustment for relevant covariates, the following variables were associated significantly with reduction in ln(UAE) in separate models: decrease in waist circumference (P = 0.001), decrease in 24-hour urine phosphorus excretion (P < 0.001), and decrease in protein intake (P = 0.01). In a multivariable model including these 3 predictors, decreases in waist circumference (P = 0.002) and 24-hour urine phosphorus excretion (P = 0.03), but not change in protein intake (P = 0.5), remained associated significantly with reduction in ln(UAE). These associations remained significant even after adjustment for changes in blood pressure and insulin resistance. Baseline UAE and metabolic syndrome modified the relationship of waist circumference with ln(UAE); specifically, individuals with higher UAE and baseline metabolic syndrome experienced greater reductions in ln(UAE) from decreases in waist circumference. LIMITATIONS: Observational study with potential for confounding. CONCLUSIONS: In adults with normal kidney function, decreases in waist circumference and 24-hour urine phosphorus excretion are associated with reductions in UAE. These findings support the rationale for clinical trials to determine whether reducing dietary phosphorus intake or waist circumference could prevent chronic kidney disease or slow its progression.

Effect of yogic intervention on the autonomic nervous system in the patients with coronary artery disease: a randomized controlled trial.

In this study 258 patients from the Department of Cardiology in Chhatrapati Shahuji Maharaj Medical University, Lucknow were selected to participate. All had been diagnosed with coronary artery disease. They were randomly divided into 2 groups, the yoga group and the non-yoga group, 129 in each group; 208 completed the study protocol. The yogic intervention consisted of 35-40 min/day, 5 days a week over a period of 18 months in the Department of Physiology. Autonomic function testing was done in both the groups at zero time and after 18 months. We observed a statistically significant reduction in body mass index, waist circumference, systolic and diastolic blood pressure, and heart rate (P < 0.05), i.e., a significant positive effect was observed when yoga therapy was used as an adjunct in patients with coronary artery disease.

Effects of yoga exercise on serum adiponectin and metabolic syndrome factors in obese postmenopausal women.

OBJECTIVE: Regular and continuous yoga exercise is one of the most important nonpharmacological methods of improving serum lipid concentrations, adipose tissue, and metabolic syndrome factors. The purpose of this study was to analyze the effects of yoga exercise on serum adiponectin and metabolic syndrome factors in obese postmenopausal Korean women. METHODS: Sixteen healthy postmenopausal women aged 54.50 ± 2.75 years with more than 36% body fat were randomly assigned to either a yoga exercise group (n = 8) or to a "no exercise" control group (n = 8). The variables of body composition, visceral fat, serum adiponectin, and metabolic syndrome factors were measured in all the participants before and after the 16-week study. RESULTS: Body weight, percentage of body fat, lean body mass, body mass index, waist circumference, and visceral fat area had significantly decreased. High-density lipoprotein cholesterol and adiponectin had significantly increased, but total cholesterol, triglyceride, low-density lipoprotein cholesterol, blood pressure, insulin, glucose, and homoeostasis model assessment-insulin resistance had significantly decreased. Serum adiponectin concentrations were significantly correlated with waist circumference, high-density lipoprotein cholesterol, diastolic blood pressure, and homoeostasis model assessment-insulin resistance in the postyoga exercise group. CONCLUSIONS: Our findings indicate that yoga exercise improves adiponectin level, serum lipids, and metabolic syndrome risk factors in obese postmenopausal women. Consequently, yoga exercise will be effective in preventing cardiovascular disease caused by obesity in obese postmenopausal Korean women.

[Assessment of the nutritional status of a group of people older than 50 years by means of dietary and body composition parameters]. / Evaluación del estado nutricional de un grupo de adultos mayores de 50 años mediante parámetros dietéticos y de composición corporal.

OBJECTIVE: To assess the nutritional status of elder adults by means of dietary and body composition parameters. METHODOLOGY: The sample comprised 49 adults, older than 50 years (23 men and 26 women) with a mean age of 54.84±4.56 years, working at a private university. The body composition was analyzed by using anthropometric parameters. The energy and nutrients intake was gathered by means of a registry of all the foods and beverages consumed during 3 days that was filled-up by each (previously instructed) participant and estimating the amounts through photographic models. Total energy requirements were estimated by the Harris-Benedict and FAO/WHO calculations. RESULTS: The body mass index was similar (p=0.018) in both men and women (26.1±1.9 and 24.4±2.8 kg/m²). The percentage of fat obtained by anthropometrics was 29.6±3.6 and 36.8±3.1% (p=0.000) in men and women, respectively. The level of physical activity was very light to light. Daily energy intake was appropriate for total energy demands when these were calculated by the calculations proposed by FAO/WHO. The caloric profile indicated an unbalance with high proteins and lipids and low carbohydrates intake. As for the micronutrients, the diets assessed indicated a deficient intake of folic acid and vitamins D and E, in both genders, and zinc and selenium also in women. CONCLUSIONS AND RECOMMENDATIONS: We have found overweight problems according to the BMI and the waist circumference, and obesity according to the body fat percentage, with the potential risk for the development of an associated complication. It would be advisable to improve the quality of the diets consumed by increasing the amount of some micronutrients and fiber, and by promoting an increase in the physical activity.
