ABSTRACT
BACKGROUND: Considering the prevalence of overweight and abdominal obesity in middle-aged women, this study was conducted to determine the effect of empowerment program to reduce sugar consumption based on the Multi-Theory Model (MTM) on Body Mass Index (BMI) and abdominal obesity in women aged 30-60 in Joven. METHODS: This quasi-experimental study (include descriptive and interventional sections) was conducted on the Joven city, Khorasan Razavi province, Iran country from October 2020 to August 2021. Sampling was performed as a multi-stage cluster. First, a descriptive study was performed among 400 women, and then 128 people who were eligible to enter the interventional phase of the study were selected. In the control group, 63 people and in the intervention group, 65 people were eligible to enter the study. The educational intervention was performed in five 60-minute sessions for groups of 12 people. The instruments included the demographic questionnaire, sugar consumption checklist and researcher-made questionnaire based on MTM constructs. Before the intervention, one, three and six months after the intervention, the questionnaire was completed by both intervention and control groups also measurement of waist circumference and BMI were performed using standard instruments. The obtained data were analyzed by SPSS 17. RESULTS: After the educational intervention, there was a significant difference between the intervention and control groups in all the MTM constructs. Also, six months after the educational intervention, BMI, waist circumference and amount of consumption of sugary substances decreased significantly in the intervention group (p < 0.05). CONCLUSION: Educational intervention based on the MTM can be effective in reducing the consumption of sugary substances and shaping behaviors related to healthy lifestyle in women.

OBJECTIVE: This study investigated the associations between adherence to the Mediterranean Diet and the Eatwell Guide (EWG) and changes in weight and waist circumference in post-menopausal women. STUDY DESIGN: Post-hoc analysis of post-menopausal women from the UK Women's Cohort Study. MAIN OUTCOME MEASURES: Changes in weight, waist circumference and the risk of abdominal and general obesity. RESULTS: 4162 post-menopausal women were selected. Higher adherence to both the EWG and the Mediterranean Diet was associated with smaller increases in waist circumference over 4 years (EWG: ß -0.47, CI -0.75, -0.20 per 1 tertile increase in score), (Mediterranean Diet: ß -0.29, CI -0.58, -0.01 per 1 tertile increase in score); and lower risk of abdominal obesity (EWG: OR 0.55, CI 0.43, 0.70 third versus the first tertile), (Mediterranean Diet: OR 0.60, CI 0.46, 0.76 third versus the first tertile), but was not associated with weight changes (EWG: ß 0.14, CI -0.07, 0.36 per 1 tertile increase in score), (Mediterranean Diet: ß 0.03, CI -0.19, 0.25 per 1 tertile increase in score) or risk of becoming overweight or obese (EWG: OR 1.09, CI 0.77, 1.52 third versus the first tertile), (Mediterranean Diet: OR 0.91, CI 0.65, 1.27 third versus the first tertile). CONCLUSIONS: The results suggest that adherence to either the Mediterranean Diet or the EWG can help to prevent abdominal obesity in post-menopausal women.

BACKGROUND: South Asians are at high risk of type 2 diabetes (T2D). Lifestyle modification is effective at preventing T2D amongst South Asians, but the approaches to screening and intervention are limited by high costs, poor scalability and thus low impact on T2D burden. An intensive family-based lifestyle modification programme for the prevention of T2D was developed. The aim of the iHealth-T2D trial is to compare the effectiveness of this programme with usual care. METHODS: The iHealth-T2D trial is designed as a cluster randomised controlled trial (RCT) conducted at 120 sites across India, Pakistan, Sri Lanka and the UK. A total of 3682 South Asian men and women with age between 40 and 70 years without T2D but at elevated risk for T2D [defined by central obesity (waist circumference ≥ 95 cm in Sri Lanka or ≥ 100 cm in India, Pakistan and the UK) and/or prediabetes (HbA1c ≥ 6.0%)] were included in the trial. Here, we describe in detail the statistical analysis plan (SAP), which was finalised before outcomes were available to the investigators. The primary outcome will be evaluated after 3 years of follow-up after enrolment to the study and is defined as T2D incidence in the intervention arm compared to usual care. Secondary outcomes are evaluated both after 1 and 3 years of follow-up and include biochemical measurements, anthropometric measurements, behavioural components and treatment compliance. DISCUSSION: The iHealth-T2D trial will provide evidence of whether an intensive family-based lifestyle modification programme for South Asians who are at high risk for T2D is effective in the prevention of T2D. The data from the trial will be analysed according to this pre-specified SAP. ETHICS AND DISSEMINATION: The trial was approved by the international review board of each participating study site. Study findings will be disseminated through peer-reviewed publications and in conference presentations. TRIAL REGISTRATION: EudraCT 2016-001,350-18 . Registered on 14 April 2016.

BACKGROUND: Identifying environmental factors that influence health in children are necessary to develop preventive strategies. OBJECTIVE: To determine the association between the lifestyles of children (i.e., Mediterranean diet (MD), physical activity (PA), fitness and screen time (ST) with abdominal obesity (AO) of preschoolers from three Spanish-speaking countries (Chile, Colombia and Spain) with different socioeconomic levels and Human Development Index (HDI) indicators. MATERIAL AND METHODS: This cross-sectional study included 982 schoolchildren (aged 4-6 years; 56.8% girls) from Chile (n = 409), Colombia (n = 281), and Spain (n = 292). Body mass index (BMI), waist circumference (WC), waist-to-height ratio (WtHR), adherence to the MD, PA, ST and physical fitness were evaluated. RESULTS: Spanish preschoolers reported a lower WtHR (p < 0.001), greater physical fitness (Z-score) (p < 0.001) and higher adherence to the MD (p < 0.001) than their Chilean and Colombian peers. In addition, Colombian preschoolers had a better lifestyle (PA + ST) than their Chilean and Spanish peers (p < 0.001). Chilean preschoolers reported a higher prevalence of AO than the Spanish preschoolers (65% vs. 51.9%; p = 0.001). CONCLUSION: Lifestyle had a significant association with AO among Spanish-speaking preschool children, with physical fitness especially being a relevant factor regardless of the country of origin. The findings of the current study may support the development of public guidelines focusing on healthy lifestyles in children to create effective plans that contribute to the early treatment of AO in preschool children.

Abstract Background The long incubation periods of cardiovascular diseases offer opportunities for controlling risk factors. In addition, preventive interventions in childhood are more likely to succeed because lifestyle habits become ingrained as they are repeated. Objective To investigate the effects of recreational physical activities, in combination or not with a qualitative nutritional counseling, in cardiometabolic risk factors of students with dyslipidemia and abdominal obesity. Methods Students (8-14 years old) were randomly divided into three groups (n=23 each): i ) Control; ii ) PANC, students undergoing Physical Activity and Nutritional Counseling, and iii ) PA, students submitted to Physical Activity, only. Blood samples (12-h fasting) were collected for biochemical analysis and anthropometric markers were also assessed. Two-Way RM-ANOVA and Holm-Sidak's test, and Friedman ANOVA on Ranks and Dunn's test were applied. P ≤ 0.05 was considered significant. Effect sizes were evaluated by Hedges' g and Cliff's δ for normal and non-Gaussian data, respectively. Results Compared to the control group and to baseline values, both interventions caused significant average reductions in total cholesterol (11%; p <0.001), LDL-c (19%; p=0.002), and non-HDL-c (19%; p=0.003). Furthermore, students in the PANC group also experienced a significant decrease in body fat compared to baseline (p=0.005) and to control (5.2%; g=0.541). Conclusions The proposed strategies were effective to reduce cardiometabolic risk factors in children and adolescents. The low cost of these interventions allows the implementation of health care programs in schools to improve the students' quality of life.

ABSTRACT Physical inactivity is associated with low heart rate variability (HRV) in adolescents. However, whether the number of physical education (PE) classes impact HRV remains unclear. This cross-sectional study verified the association between the frequency of PE classes and HRV parameters in male adolescents. This study included 1152 boys (16.6 ± 1.2 years). The quantity of PE classes was assessed though questionnaire and the adolescents were stratified accordingly (no PE class; one PE class/wk; ≥2 PE classes/wk). Time- (SDNN, RMSSD, PNN50) and frequency-domains (LF, HF, sympathovagal balance) of HRV were obtained. Generalized Linear Models were used for comparing the HRV parameters according to the quantity of PE classes, adjusting for confounders. There was no difference in HRV measures of time: (SDNN, p = 0.77; RMSSD, p=0.72; PNN50, p=0.83) and frequency (LF, p=0.61; HF, p=0.61; sympathovagal balance, p=0.60) between the different frequencies of PE classes. The frequency of PE classes in not associated with HRV parameters of male adolescents.
RESUMO A inatividade física está associada à baixa variabilidade da frequência cardíaca (VFC) em adolescentes. Entretanto, não está claro se o número de aulas de Educação Física (EF) causa impacto na VFC. Este estudo transversal verificou a associação entre a frequência das aulas de EF com parâmetros de VFC em adolescentes do sexo masculino. Foram incluídos 1.152 meninos (16,6 ± 1,2 anos). A quantidade de aulas de EF foi avaliada através de questionário e os adolescentes foram estratificados de acordo (nenhuma aula de EF; uma aula de EF / sem; ≥2 aulas de EF / sem). Os domínios do tempo (SDNN, RMSSD, PNN50) e da frequência (LF, HF, balanço simpático-vagal) da VFC foram obtidos. Modelos Lineares Generalizados foram usados para comparar os parâmetros da VFC de acordo com a quantidade de aulas de EF, ajustando para fatores de confusão. Não houve diferença nas medidas de VFC de tempo: (SDNN, p = 0,77; RMSSD, p = 0,72; PNN50, p = 0,83) e frequência (LF, p = 0,61; HF, p = 0,61; balanço simpatovagal, p = 0,60) entre as diferentes frequências das aulas de EF. A frequência das aulas de EF não está associada aos parâmetros de VFC de adolescentes do sexo masculino.

ABSTRACT: Diet plays a crucial role as a modifiable risk factor related to the development of metabolic syndrome (MetS) and its cluster. Constitution type of traditional Korean medicine has shown accuracy to predict the risk for MetS. We attempted to examine the association between nutritional status, pre-MetS, and its cluster in Korean adults by their constitution type.Participants aged 30 to 55âyears who had no cancer or cardiovascular diseases (CVDs) were assigned to join in the present study. Pre-MetS was defined as ≥2 of the following factors: abdominal obesity; elevated triglycerides (TG); reduced high-density lipoprotein cholesterol (HDL-C); elevated blood pressure (BP); and elevated fasting plasma glucose (FPG). Constitution type was categorized into Tae-Eumin (TE) or non-TE. Dietary assessment of the subjects were surveyed using a short-form of the food frequency questionnaire (FFQ) and the nutrition quotient (NQ), which uses 4 factors, namely, balance, diversity, moderation, and dietary behavior.A total of 986 subjects were evaluated by constitution type with MetS status. Of these subjects, 48.6% had pre-MetS, 89.5% were obese and had the highest waist circumference (WC) in Pre-MetS TE. BP, FPG, TG were higher, while HDL-C was lower, than normal TE or non-TE both in Pre-MetS TE and non-TE. The prevalence of pre-MetS was positively associated with lower status of dietary behavior (odds ratio [ORs]: 2.153, 95% confidence interval [CI]: 1.179-3.931) while negatively related to higher vegetables and fruits intakes (ORs: 0.594, 95% CI: 0.359-0.983) in TE. Lower status of NQ had about 2 times higher risk of Pre-MetS (ORs: 1.855, 95% CI: 1.018-3.380) and abdominal obesity (ORs: 2.035, 95% CI: 1.097-3.775) in TE compared with higher status of NQ after controlling for covariates.Poor diet was a key contributor to the development of Pre-MetS and abdominal obesity in Korean adults with TE. Customized nutrition care and integrated medicinal approaches are strongly suggested to conduct optimal preventive care for people who are vulnerable to health risk.

BACKGROUND: Central obesity is a major manifestation of metabolic syndrome, which is a common health problem in middle-aged and older adults. OBJECTIVE: To examine the therapeutic efficacy of tai chi for management of central obesity. DESIGN: Randomized, controlled, assessor-blinded trial. (ClinicalTrials.gov: NCT03107741). SETTING: A single research site in Hong Kong between 27 February 2016 and 28 February 2019. PARTICIPANTS: Adults aged 50 years or older with central obesity. INTERVENTION: 543 participants were randomly assigned in a 1:1:1 ratio to a control group with no exercise intervention (n = 181), conventional exercise consisting of aerobic exercise and strength training (EX group) (n = 181), and a tai chi group (TC group) (n = 181). Interventions lasted 12 weeks. MEASUREMENTS: Outcomes were assessed at baseline, week 12, and week 38. The primary outcome was waist circumference (WC). Secondary outcomes were body weight; body mass index; high-density lipoprotein cholesterol (HDL-C), triglyceride, and fasting plasma glucose levels; blood pressure; and incidence of remission of central obesity. RESULTS: The adjusted mean difference in WC from baseline to week 12 in the control group was 0.8 cm (95% CI, -4.1 to 5.7 cm). Both intervention groups showed reductions in WC relative to control (adjusted mean differences: TC group vs. control, -1.8 cm [CI, -2.3 to -1.4 cm]; P < 0.001; EX group vs. control: -1.3 cm [CI, -1.8 to -0.9 cm]; P < 0.001); both intervention groups also showed reductions in body weight (P < 0.05) and attenuation of the decrease in HDL-C level relative to the control group. The favorable changes in WC and body weight were maintained in both the TC and EX groups, whereas the beneficial effect on HDL-C was only maintained in the TC group at week 38. LIMITATIONS: High attrition and no dietary intervention. CONCLUSION: Tai chi is an effective approach to reduce WC in adults with central obesity aged 50 years or older.

Fibrates, including fenofibrate, are a class of hypolipidemic drugs that activate peroxisome proliferator-activated receptor α (PPARα), which in-turn regulates the expression of lipid and lipoprotein metabolism genes. We investigated whether fenofibrate can reduce visceral obesity and nonalcoholic fatty liver disease via adipose tissue PPARα activation in female ovariectomized (OVX) C57BL/6J mice fed a high-fat diet (HFD), a mouse model of obese postmenopausal women. Fenofibrate reduced body weight gain (-38%, p < 0.05), visceral adipose tissue mass (-46%, p < 0.05), and visceral adipocyte size (-20%, p < 0.05) in HFD-fed obese OVX mice. In addition, plasma levels of alanine aminotransferase and aspartate aminotransferase, as well as free fatty acids, triglycerides, and total cholesterol, were decreased. Fenofibrate also inhibited hepatic lipid accumulation (-69%, p < 0.05) and infiltration of macrophages (-72%, p < 0.05), while concomitantly upregulating the expression of fatty acid ß-oxidation genes targeted by PPARα and decreasing macrophage infiltration and mRNA expression of inflammatory factors in visceral adipose tissue. These results suggest that fenofibrate inhibits visceral obesity, as well as hepatic steatosis and inflammation, in part through visceral adipose tissue PPARα activation in obese female OVX mice.

Metabolic syndrome is linked to an increased risk of cardiovascular complications by a mechanism involving mainly decreased nitric oxide (NO) bioavailability and impaired NO-soluble guanylate cyclase (sGC)- cyclic guanosine monophosphate (cGMP) signalling (NO-sGC-cGMP). To further develop this scientific point, this study aimed to investigate the effects of long-term treatment with BAY 41-2272 (a sGC stimulator) on cardiovascular reactivity of spontaneously hypertensive rats (SHR) as a model of metabolic syndrome. SHR were randomly divided into 3 groups: control group, cafeteria diet (CD)-fed group and CD-fed group treated daily with BAY 41-2272 (5 mg/kg) by gastric gavage for 12 weeks. In vivo measurements of body weight, abdominal circumference, blood pressure and glucose tolerance test were performed. At the end of the feeding period, ex vivo cumulative concentration-response curves were performed on isolated perfused heart (isoproterenol (0.1 nM - 1 µM)) and thoracic aorta (phenylephrine (1 nM-10 µM), acetylcholine (1 nM-10 µM), and sodium nitroprusside (SNP) (0.1 nM-0.1 µM)). We showed that chronic CD feeding induced abdominal obesity, hypertriglyceridemia, glucose intolerance and exacerbated arterial hypertension in SHR. Compared to control group, CD-fed group showed a decrease in ß-adrenoceptor-induced cardiac inotropy, in coronary perfusion pressure and in aortic contraction to phenylephrine. While relaxing effects of acetylcholine and SNP were unchanged. BAY 41-2272 long-term treatment markedly prevented arterial hypertension development and glucose intolerance, enhanced the α1-adrenoceptor-induced vasoconstriction, and restored cardiac inotropy and coronary vasodilation. These findings suggest that BAY 41-2272 may be a potential novel drug for preventing metabolic and cardiovascular complications of metabolic syndrome.

BACKGROUND & AIMS: The visceral adiposity index (VAI) has been shown to be a reliable estimate of visceral adiposity, but little is known about its association with specific dietary patterns such as the Dietary Approaches to Stop Hypertension (DASH) diet, particularly in older adults. Many studies have shown the DASH diet to be beneficial for cardiometabolic health. The purpose of this study was to investigate the relationship between DASH diet scores and the VAI in older adults using a nationally representative dataset. METHODS: Using the National Health and Nutrition Examination Surveys (NHANES) from 2011 to 2014, data from 508 community-dwelling older adults were examined, and dietary intake was evaluated using the Dixon's DASH diet index. Using multiple linear regression analysis, the relationship between VAI and DASH diet score was assessed while controlling for demographic variables. RESULTS: Participants' average DASH diet score was 2.41 (SE = 0.07), and the average VAI was 1.55 (SE = 0.08). The results suggest a significant inverse relationship between the DASH diet and VAI (ß = -0.19, t = -2.73, p = 0.009). CONCLUSIONS: Results of this study suggest that protective properties of the DASH diet pattern may be due in part to its inverse relationship with visceral adiposity. This information supports practitioners' use of the VAI with older adults in addition to providing nutrition counseling with the DASH diet to reduce patients' cardiometabolic risk.

OBJECTIVE: The present study was aimed to reveal the relationship between uric acid and fructose-induced obesity hypertension and its mechanisms. METHODS: A rat model with obesity hypertension was induced by a high-fructose diet. In the experiment I, the rats were fed with fructose for 8 wks along with allopurinol or benzbromarone at the beginning. In the experiment II, the rats were fed with fructose for 8 wks firstly. And then, these rats were treated with allopurinol or benzbromarone for additional 6 wks. RESULTS: Fructose-fed rats showed hyperuricemia, abdominal obesity hypertension and an activation in adipose renin-angiotensin system (RAS). Also, fructose-fed rats had higher levels of proinflammatory cytokines and more macrophages infiltrating in adipose tissue. In the experiment I, allopurinol and benzbromarone significantly reduced serum uric acid at 8 wk. Adipose RAS overactivation, adipose inflammatory responses and the development of obesity hypertension were all effectively prevented by hyperuricemia inhibition. In the experiment II, 6-wk treatment with allopurinol and benzbromarone significantly decreased serum uric acid, downregulated adipose RAS, abolished adipose inflammation and improved obesity hypertension. CONCLUSION: In conclusion, urate-lowering therapy protects rats against fructose-induced obesity hypertension. The mechanisms appear to be via downregulated adipose RAS and reduced inflammation in adipose tissue.

Menopause consequent to reduced circulating estrogen is associated with diminished insulin receptor sensitivity and fat redistribution, particularly central adiposity and increased waist circumference. Peri and menopausal women are at risk of hyperglycemia, prediabetes and attendant metabolic disturbances. Hormone replacement therapy increases insulin receptor sensitivity, but may precipitate an increased cardiovascular risk, depending on the route, if not commenced within the proposed period denoted by the 'timing hypothesis'. The therapeutic ideal of dietary modification with increased physical activity may have compliance issues. We theorize that selected antidiabetic agents reduce visceral fat deposits, restore insulin sensitivity and inhibit inflammatory mediator release. Glucagon-like peptide 1 agonists, sodium-glucose cotransporter 2 inhibitors and even metformin are worthy interventions to treat menopausal-induced obesogenic metabolic conditions. Loss of visceral fat restores insulin receptor sensitivity, decreases central obesity and adipokines to halt dysmetabolic changes.

Although abdominal obesity plays a fundamental role in the onset of immune and inflammatory reactions leading to cardiac abnormalities and premature mortality, the potential association between periumbilical fat and longevity mediated by the antibody-complement system and/or cardiac structure and function remains unclear. To address this issue, we collected biochemical and morphological data from 419 centenarians and 491 non-centenarian oldest-old individuals from the China Hainan Centenarian Cohort Study. Centenarians had lower waist circumference (WC), periumbilical fat thickness (PFT), serum complement C3 level, right atrium end-systolic diameter (RAESD), left atrium end-systolic diameter (LAESD), and left ventricular end-diastolic diameter (LVEDD) than non-centenarians (P<0.05 for all comparisons). WC, PFT, complement C3 levels, RAESD, LAESD, and LVEDD were inversely associated with centenarians (P<0.05 for all variables). Complement C3 level, LAESD, and LVEDD were positively associated with PFT and WC (P<0.05 for all variables). RAESD was positively associated with WC and complement C3 level (P<0.05 for both variables). Centenarians had less periumbilical fat, a weaker complement system, and smaller cardiac structure than non-centenarians. Importantly, periumbilical fat was inversely associated with longevity mediated by complement C3 and cardiac structure. This study suggests that successful aging can be promoted by increased efforts to prevent abdominal obesity.

BACKGROUND: The study aimed to investigate the association between daily consumption of coffee or green tea, with and without habitual bread consumption for breakfast, and components and prevalence of metabolic syndrome in Japanese populations. METHODS: The study population consisted of 3539 participants (1239 males and 2300 females). Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression analyses to evaluate the associations of daily coffee and green tea consumption with the prevalence of obesity, visceral obesity, and metabolic syndrome. RESULTS: Coffee consumption was associated with significantly lower proportions of visceral obesity (OR: 0.746, CI: 0.588-0.947) and metabolic syndrome (OR: 0.706, CI: 0.565-0.882). On the other hand, green tea was not associated with visceral obesity (OR: 1.105, CI: 0.885-1.380) or metabolic syndrome (OR: 0.980, CI: 0.796-1.206). The combination of daily drinking coffee and eating bread at breakfast time was associated with significantly lower proportions of obesity (OR: 0.613, CI: 0.500-0.751) (p = 0.911 for interaction), visceral obesity (OR: 0.549, CI: 0.425-0.710) (p = 0.991 for interaction), and metabolic syndrome (OR: 0.586, CI: 0.464-0.741) (p = 0.792 for interaction). CONCLUSION: Coffee consumption was significantly associated with lower visceral adipose tissue and lower proportions of visceral obesity, but the same was not true for green tea consumption. Furthermore, in combination with coffee consumption, the addition of eating bread at breakfast time significantly lowered proportions of visceral obesity and metabolic syndrome, although there was no interaction between coffee and bread.

Pathogenicity of visceral adipose tissue (VAT) has been linked to the metabolic stress of enlarging mature adipocytes and a limited ability to recruit new adipocytes. One of the major distinguishing features of VAT preadipocytes is the high expression of the zinc metalloprotease, pregnancy-associated plasma protein-A (PAPP-A), when compared to subcutaneous adipose tissue (SAT). In this study we used 2 different approaches to investigate the effect of PAPP-A inhibition on different fat depots in mice on a high-fat diet (HFD) for 15 weeks. Conditional knockdown of PAPP-A gene expression in female adult mice resulted in significant decreases of 30% to 40% in adipocyte size in VAT (mesenteric and pericardial depots) compared to control mice. There was no effect on SAT (inguinal) or intra-abdominal perigonadal fat. Liver lipid was also significantly decreased without any effect on heart and skeletal muscle lipid. We found similar effects when using a pharmacological approach. Weekly injections of a specific immunoneutralizing monoclonal antibody (mAb-PA 1/41) or isotype control were given to male and female wild-type mice on HFD for 15 weeks. Adipocyte size was significantly decreased (30%-50%) only in VAT with mAb-PA 1/41 treatment. In this model, cell number was significantly increased in mesenteric fat in mice treated with mAb-PA 1/41, suggesting hyperplasia along with reduced hypertrophy in this VAT depot. Gene expression data indicated a significant decrease in F4/80 (macrophage marker) and interleukin-6 (proinflammatory cytokine) and a significant increase in adiponectin (anti-inflammatory adipokine with beneficial metabolic effects) in mesenteric fat compared to inguinal fat in mice treated with mAb-PA 1/41. Furthermore, there was significantly decreased liver lipid content with mAb-PA 1/41 treatment. Thus, using 2 different models systems we provide proof of principle that PAPP-A inhibition is a potential therapeutic target to prevent visceral obesity and its metabolic sequelae, such as fatty liver.

PURPOSE: This study aims to determine whether breastfeeding may have any beneficial effects on metabolic syndrome in a cohort of postmenopausal Korean women. METHODS: A cross-sectional study with secondary data analysis was conducted using the cohort in the Korean Genome and Epidemiology Study. Data from 1,983 postmenopausal women were analyzed by logistic regression analysis. Controlled covariates were chosen based on a biopsychosocial model and included age, family history of hypertension; type 2 diabetes mellitus; and cerebro-cardiovascular diseases, body mass index, age of menarche, parity, socioeconomic status of family, educational level, past or current smoking experience, and current alcohol consumption experience. RESULTS: Breastfeeding experience and duration were not significantly associated with a decreased likelihood of metabolic syndrome among postmenopausal women. However, breastfeeding experience (adjusted odds ratio [AOR]: 0.52 [p = .010]) and a total duration of breastfeeding exceeding 3 months were significantly associated with decreased likelihood of abdominal obesity (≥3 and < 6 months: AOR: 0.49 [p = .014]; ≥6 and < 12 months: AOR: 0.51 [p = .009]; ≥12 months: AOR: 0.56 [p = .024]). CONCLUSION: Our findings indicate that breastfeeding might have beneficial effects on reducing abdominal obesity in postmenopausal women. Health-care providers should publicize beneficial long-term effects of breastfeeding on the prevention of abdominal obesity, a component of metabolic syndrome.

BACKGROUND AND OBJECTIVES: This study evaluated the association of the Mediterranean Diet Quality Index (KIDMED index) with neck circumference, obesity, and abdominal obesity in a national sample of Turkish children aged 6-9 years. It was hypothesized that the Mediterranean diet has beneficial effects on BMI and waist and neck circumferences in children. METHODS AND STUDY DESIGN: The study sample consisted of 900 children aged 6-9 years recruited from seven primary schools in Ünye District in Ordu, Turkey. Anthropometric data were collected. The KIDMED score was used to assess the children's adherence to the Mediterranean diet. RESULTS: Compared with girls, a higher percentage of boys were obese (27.9% vs 22.2%), and the KIDMED score differed between boys (4.89±2.0) and girls (5.27±2.48; p<0.05). Only 18.7% of children had optimal KIDMED scores, and 35.7% had poor KIDMED scores. Compared with boys and girls with medium and optimal KIDMED scores, boys and girls with poor KIDMED scores had higher body weight, height, BMI, and waist and neck circumferences (p<0.05). KIDMED scores of overweight boys and girls were higher than those of obese boys and girls (p<0.05). An inverse correlation was found between KIDMED scores and body weight, BMI, and waist and neck circumferences. CONCLUSIONS: The Mediterranean dietary pattern is significantly associated with improved anthropometric measurements in children. These results demonstrate that providing a diet similar to the Mediterranean diet can prevent obesity and related disorders in children.

BACKGROUND: A global epidemic of obesity has been documented, particularly among African countries. While central obesity and overweight have been reported for many countries, very limited information exists about the prevalence of these health problems in Sudan, and these data are nonexistent for Eastern Sudan. The present study aimed to determine the prevalence of obesity and central obesity, as well as the factors associated with both, among adults in Gadarif, Eastern Sudan. METHODS: A cross-sectional study was conducted in Gadarif, Eastern Sudan, during the period of January through May 2018. Sociodemographic and health characteristics data were collected through a questionnaire. Body mass index (BMI) and waist circumference (WC) were measured using the standard methods. Both descriptive and inferential statics were applied to analyze the data. RESULTS: A total of 594 adults participated in the study; 70.4% of them were female. The mean (standard deviation) age was 44.98 (16.64) years. Of the 594 enrolled participants, 33.7%, 7.4%, 26.8%, and 32.2% were normal weight, underweight, overweight, and obese, respectively. The prevalence of central obesity was (67.8%). Approximately, one-third of the participants (29.29%) were obese and had central obesity. In the multinomial regression, being married was the main risk factor associated with overweight, and older age, female sex, being married and hypertension were significantly associated with obesity. In the binary regression, the main risk factors associated with central obesity were female sex and being married. CONCLUSION: The prevalence rates of both obesity and central obesity among the study participants were high. Older age and hypertension were only associated with obesity. Obesity and central obesity were significantly associated with female sex and being married. This study provided valuable baseline information to develop appropriate strategies for the prevention and control of obesity in Eastern Sudan.
