Ferritin, metabolic syndrome and NAFLD: Elective attractions and dangerous liaisons

Objective:This study aims to compare the prevalence of metabolic syndrome between different age groups of middle-aged and older women and to assess whether these differences are independent of potential covariates.Methods:Study conducted with 510 women divided into three age groups: 45–54, 55–64 and 65–74 years. Socioeconomic, reproductive and lifestyle variables were self-reported. We defined metabolic syndrome using the National Cholesterol Education Program Adult Treatment Panel III criteria (abdominal obesity, diabetes, reduced high-density lipoprotein, elevated triglycerides, and hypertension). Logistic regression assessed the association between age groups, and metabolic syndrome was adjusted for covariates (socioeconomic variables, age at menarche and at first childbirth, parity, menopausal status, physical activity variables and smoking).Results:Women aged 55–64 years presented higher prevalence of all metabolic syndrome criteria than the other groups, except for abdominal obesity, which was higher in the oldest group. In the fully adjusted analysis, the 55–64 years age group continues to exhibit significantly higher odds of presenting metabolic syndrome when compared to the youngest group (45–54 years) (OR = 2.257; 95% CI = 1.20:4.24). There was no statistical difference in the odds of presenting metabolic syndrome when comparing the oldest and the youngest groups (OR = 1.500; 95% CI = 0.85:2.65).Conclusion:The higher prevalence of metabolic syndrome among those aged 55–64 years may indicate that middle-aged women become unhealthy earlier in the life course and that many of them may die prematurely. This result highlights the importance of screening metabolic syndrome earlier in the midlife and the need for public health policies aimed at reducing adverse effects in later years.

To evaluate the risk of breast cancer in middle-aged women with metabolic syndrome using the National Health Insurance Service-National Sample Cohort (NHIS-NSC). We analyzed 23,820 women aged 50-64years who participated in the NHIS-NCS in 2008 and 2009. We excluded subjects with any previous history of cancer or with inadequate information regarding metabolic syndrome. Participated subjects underwent anthropometric measurements and provided fasting blood samples for the assessment of glucose and lipid profiles, and answered a lifestyle questionnaire. Cox regression analysis was performed to evaluate relative risks (RRs) and 95% confidence intervals (CIs) for the association between metabolic syndrome and breast cancer. During the 5-year follow-up, 131 subjects were newly diagnosed with breast cancer (incidence, 10.86 per 10,000 person years). After adjusting for age and body mass index, the RR for incident breast cancer in participants with metabolic syndrome versus those without it was 1.47 (95% CI 1.01-2.13). For those individuals of metabolic syndrome, hyperglycemia was most primarily related with the incidence of breast cancer (RR 1.44, 95% CI 1.02-2.04). Among the study individuals who were middle-aged Korean women, metabolic syndrome is highly related with the risk of breast cancer. Therefore, it needs to be managed or prevented to reduce the incidence of breast cancer.

Background: Clinical studies have demonstrated that higher protein intake based on caloric restriction (CR) alleviates metabolic abnormalities. However, no study has examined the effects of plasma protein profiles on caloric restriction with protein supplementation (CRPS) in metabolic syndrome (MetS). Therefore, using a proteomic perspective, this pilot study investigated whether CRPS ameliorated metabolic abnormalities associated with MetS in middle-aged women. Methods: Plasma samples of middle-aged women with MetS in CR (n = 7) and CRPS (n = 6) groups for a 12-week intervention were obtained and their protein profiles were analysed. Briefly, blood samples from qualified participants were drawn before and after the dietary treatment. Anthropometric, clinical, and biochemical variables were measured and correlated with plasma proteomics. Results: In results, we found that body mass index, total body fat, and fasting blood glucose decreased significantly after the interventions but were not different between the CR and CRPS groups. After liquid chromatography–tandem mass spectrometry analysis, the relative plasma levels of alpha-2-macroglobulin (A2M), C4b-binding protein alpha chain (C4BPA), complement C1r subcomponent-like protein (C1RL), complement component C6 (C6), complement component C8 gamma chain (C8G), and vitamin K-dependent protein S (PROS) were significantly different between the CRPS and CR groups. These proteins are involved in inflammation, the immune system, and coagulation responses. Moreover, blood low-density lipoprotein cholesterol levels were significantly and positively correlated with C6 plasma levels in both groups. Conclusions: These findings suggest that CRPS improves inflammatory responses in middle-aged women with MetS. Specific plasma protein expression (i.e., A2M, C4BPA, C1RL, C6, C8G, and PROS) associated with the complement system was highly correlated with fasting blood glucose (FBG), blood lipids (BLs), and body fat.

Metabolic syndrome is one of the emerging health issues in developing countries. It includes diabetes, high blood pressure, obesity, and elevated blood cholesterol. This study aimed to compare the effects of two different types of interventions: multi-interventional therapy (MIT) and lifestyle interventions (LIs) on high-density lipoprotein (HDL), triglycerides, and fasting blood sugar (FBS) among women with metabolic syndrome. The study used a quasi-experimental nonequivalent control group design with two experimental groups and one control group. This study was conducted among self-help group women from nine area development societies (ADS) in a selected area in South India from March 1, 2019, to February 28, 2020. Women (aged between 35 and 55 years) with metabolic syndrome were recruited by multistage sampling (N = 220) and randomly assigned into three groups: (a) control, (b) MIT (intervention 1), and (c) LIs (intervention 2). Reflexology foot massage, dietary modification, moderate-intensity exercise, and structured education were given to the MIT group and dietary modification, moderate-intensity exercise, and structured education were given to the LI group for 12 weeks. The control group received routine care. A demographic and clinical data sheet is used to collect the basic information. Biochemical variables (HDL, triglycerides, and FBS) were assessed before and after the intervention. The data obtained from the study were computed using a frequency distribution to describe the demographic characteristics, and a Chi-square (x2) test was conducted to find the homogeneity. Both parametric and nonparametric tests were conducted for the comparison of the effectiveness of different methods of interventions on biochemical parameters of metabolic syndrome. Women who received MIT and LI had significantly lower values of HDL, triglycerides, and FBS after the treatment from baseline and compared with the control group. The study found a significant improvement in the biochemical parameters in the MIT group as compared to the control group and the LI group (<0.001). Paired t-test shows significant improvement in HDL, triglycerides, and FBS (P < 0.001) in both the LI and MIT groups. In case of triglycerides, MIT was found to be more effective (P < 0.001). Both MIT and LIs can be considered interventions for reducing triglycerides and FBS and increasing HDL.

Metabolic syndrome in women with polycystic ovary syndrome

Dietary restriction (DR) reduces adiposity and improves metabolism in patients with one or more symptoms of metabolic syndrome. Nonetheless, it remains elusive whether the benefits of DR in humans are mediated by calorie or nutrient restriction. This study was conducted to determine whether isocaloric dietary protein restriction is sufficient to confer the beneficial effects of dietary restriction in patients with metabolic syndrome. We performed a prospective, randomized controlled dietary intervention under constant nutritional and medical supervision. Twenty-one individuals diagnosed with metabolic syndrome were randomly assigned for caloric restriction (CR; n = 11, diet of 5941 ± 686 KJ per day) or isocaloric dietary protein restriction (PR; n = 10, diet of 8409 ± 2360 KJ per day) and followed for 27 days. Like CR, PR promoted weight loss due to a reduction in adiposity, which was associated with reductions in blood glucose, lipid levels, and blood pressure. More strikingly, both CR and PR improved insulin sensitivity by 62.3% and 93.2%, respectively, after treatment. Fecal microbiome diversity was not affected by the interventions. Adipose tissue bulk RNA-Seq data revealed minor changes elicited by the interventions. After PR, terms related to leukocyte proliferation were enriched among the upregulated genes. Protein restriction is sufficient to confer almost the same clinical outcomes as calorie restriction without the need for a reduction in calorie intake. The isocaloric characteristic of the PR intervention makes this approach a more attractive and less drastic dietary strategy in clinical settings and has more significant potential to be used as adjuvant therapy for people with metabolic syndrome.

Do sex hormones influence features of the metabolic syndrome in middle-aged women? A population-based study of Swedish women: The Women’s Health in the Lund Area (WHILA) Study

To investigate whether physical activity is a protective factor against metabolic syndrome in middle-aged and older women. Socio-demographic and lifestyle behaviour factors contribute to metabolic syndrome. To minimise the risk of metabolic syndrome, several global guidelines recommend increasing physical activity level. However, only limited research has investigated the relationship between physical activity levels and metabolic syndrome in middle-aged and older women after adjusting for socio-demographic and lifestyle behaviour factors. Cross-sectional design. A convenience sample of 326 middle-aged and older women was recruited. Metabolic syndrome was confirmed according to the National Cholesterol Education Program, Adult Treatment Panel III guidelines, and physical activity levels were measured by the International Physical Activity Questionnaire. The sample had a mean age of 60·9 years, and the prevalence of metabolic syndrome was 43·3%. Postmenopausal women and women with low socioeconomic status (low-education background, without personal income and currently unemployed) had a significantly higher risk of developing metabolic syndrome. After adjusting for significant socio-demographic and lifestyle behaviour factors, the women with moderate or high physical activity levels had a significantly lower (OR = 0·10; OR = 0·11, p < 0·001) risk of metabolic syndrome and a lower risk for each specific component of metabolic syndrome, including elevated fasting plasma glucose (OR = 0·29; OR = 0·26, p = 0·009), elevated blood pressure (OR = 0·18; OR = 0·32, p = 0·029), elevated triglycerides (OR = 0·41; OR = 0·15, p = 0·001), reduced high-density lipoprotein (OR = 0·28; OR = 0·27, p = 0·004) and central obesity (OR = 0·31; OR = 0·22, p = 0·027). After adjusting for socio-demographic and lifestyle behaviour factors, physical activity level was a significant protective factor against metabolic syndrome in middle-aged and older women. Higher physical activity levels (moderate or high physical activity level) reduced the risk of metabolic syndrome in middle-aged and older women. Appropriate strategies should be developed to encourage middle-aged and older women across different socio-demographic backgrounds to engage in moderate or high levels of physical activity to reduce the risk of metabolic syndrome.

Background: Dietary restriction (DR) reduces adiposity and improves metabolism in patients with one or more symptoms of the metabolic syndrome. Nonetheless, it remained elusive whether the benefits of DR in humans are mediated by calorie or nutrient restriction. Methods: Here we subjected 21 individuals diagnosed with the metabolic syndrome to short-term (i.e., 27-days) caloric restriction (CR; n = 11) or isocaloric dietary protein restriction (PR; n = 10) and compared the metabolic outcomes of the interventions. Findings: Like CR, PR promoted weight loss due to reduction in adiposity, and reduced blood glucose, lipid levels and blood pressure in these individuals. Hence, a reduction in calorie intake is not necessary to confer the metabolic benefits of DR. Instead, a reduction in protein intake with a mild increase in carbohydrate intake to maintain the caloric balance of the diet is sufficient to improve metabolic control in patients with the metabolic syndrome. Interpretation: Because PR is a less drastic food intervention to be conducted, it has a greater potential to be used as an adjuvant therapy to treat the metabolic syndrome.

Mid-life obesity has been reported to be a significant risk factor for later-life dementia and Alzheimer's disease. Metabolic syndrome (MetS) has been suggested to have an adverse effect while cardiorespiratory fitness (CRF) has been suggested to have a protective effect on cognitive function of older adults. However, studies investigating such effects in middle-aged obese women are limited. To compare cognitive performances between obese and normal weight middle-aged women and examine the effects of MetS and CRF on cognitive performances when combined with obesity. Cross-sectional study with the data of 87 middle-aged women (58 obese and 29 normal weight, with age and education matched). The non-invasive screening method for metabolic syndrome (NIM-MetS) was used to detect MetS. CRF was determined by using maximal oxygen consumption (VO2 max) and was classified as high or low (VO2 max higher or lower than 50th percentile) based on the American College of Sports Medicine's guidelines. Neurocognitive tests including Montreal Cognitive Assessment (MoCA), digit span (DS), trail making test (TMT), hand reaction time (HRT), logical memory (LM), and semantic verbal fluency test (SVFT) were administered to all participants. The obese group demonstrated significantly lower score in MoCA, DS, TMT, HRT, and LM than the normal weight group (p < 0.05). The obese with MetS subgroup (n = 28) showed significantly lower score in LM than the obese non-MetS subgroup (n = 30) (p = 0.002). Normal weight with high CRF participants (NW-high CRF; n = 28) demonstrated significantly higher score in MoCA and HRT than obese with high CRF participants (OB-high CRF; n = 24) (p < 0.05), and demonstrated better score in MoCA, DS, TMT, HRT, and LM than obese with low CRF participants (OB-low CRF; n = 24) (p < 0.05). OB-high CRF showed significantly greater score in DS, TMT and LM than OB-low CRF (p < 0.05). Obesity shows negative impact on several cognitive functions, which memory appears to be further affected when combined with MetS in middle-aged women, whereas CRF is suggested to have benefit on certain aspects of cognitive domains. Maintaining a healthy body weight and improving CRF are beneficial for cognitive function of middle-aged women.

1539 Background: The WHI Diet Modification (DM) trial randomized 48,835 postmenopausal women with no prior breast cancer to a low-fat dietary intervention or comparison group. After 16.1 years follow-up, the intervention was associated with an 18% reduction in risk of death after breast cancer (P =0.01), with greater reduction (29%) in those with waist circumference≥88 cm (J Clin Oncol 2017). To extend these findings, we examined the influence of the dietary intervention on breast cancer mortality in subgroups defined by number of metabolic syndrome (MS) components with 19.6 years median cumulative follow-up. Methods: WHI DM has been previously described. Four MS components were determined at entry: 1) waist circumference≥ 88 cm, 2) high blood pressure or anti-hypertensive use, 3) high cholesterol history and 4) diabetes history, with women categorized as having 0 (n=10,639), 1-2 (n=30,948), or 3-4 (n=4,246) MS components. Forest plots of hazard ratios (HRs) were generated with P-values for interaction between randomized group assignment and number of MS components. Results: Women with 3-4 MS components were more likely to be Black, be obese (BMI ≥30), and have diabetes (all P &lt; 0.001). Breast cancers in women with 3-4 MS components were less likely to be local stage (P = 0.005) or well differentiated (P = 0.03). The magnitude of reduction in deaths from breast cancer in the dietary intervention vs comparison group increased as the number of MS components increased (interaction P = 0.01). Hazard ratios (HR) and 95% confidence intervals (CI) for death from breast cancer for intervention vs comparison groups for women with 0 MS components was 1.09 95% CI, 0.63-1.87, with risk low in both randomization groups (0.028% and 0.026%, respectively); for women with 1-2 MS components, HR 0.80 95% CI 0.62-1.02; and for women with 3-4 MS components, HR 0.31 95% CI, 0.14-0.69, with risk in the intervention group reduced to 0.026%. Conclusions: Adoption of a low-fat dietary pattern had a greater effect on reducing deaths from breast cancer in women with more MS components, suggesting that this is a high risk group more likely to benefit from the dietary intervention.

The aim of this study was to assess clinical and inflammatory markers in nonalcoholic fatty liver disease (NAFLD) in postmenopausal women with metabolic syndrome. This cross-sectional study included 180 Brazilian women (age ≥45 years and amenorrhea ≥12 months). Metabolic syndrome was diagnosed by the presence of at least three of the following indicators: Waist circumference (WC) >88 cm, triglycerides (TGs) ≥150 mg/dL, high-density lipoprotein (HDL) <50 mg/dL; blood pressure ≥130/85 mmHg; and glucose ≥100 mg/dL. NAFLD was diagnosed by abdominal ultrasound. Participants were divided into three groups: Metabolic syndrome alone (n=53); metabolic syndrome+NAFLD (n=67); or absence of metabolic syndrome or NAFLD (control, n=60). Clinical, anthropometric, and biochemical variables were quantified. The inflammatory profile included adiponectin, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). Data were submitted to statistical analysis using a Tukey test, analysis of variance (ANOVA), chi-squared, Pearson correlation, and logistic regression (odds ratio, OR). Women with metabolic syndrome+NAFLD, abdominal obesity, high glucose, and insulin resistance by HOMA-IR were compared to women with metabolic syndrome alone and controls (P<0.05). High values of IL-6 and TNF-α and low values of adiponectin were observed among women with metabolic syndrome alone or metabolic syndrome+NAFLD when compared to controls (P<0.05). In multivariate analysis, the variables considered as risk of NAFLD development were: High systolic blood pressure (SBP) [(OR 1.02, 95% confidence interval (CI) 1.0-1.04]; large WC (OR 1.07, 95% CI 1.01-1.13); insulin resistance (OR 3.81, 95% CI 2.01-7.13); and metabolic syndrome (OR 8.68, 95% CI 3.3-24.1). Adiponectin levels reduced NAFLD risk (OR 0.88, 95% CI 0.80-0.96). In postmenopausal women, metabolic syndrome, abdominal obesity, and insulin resistance were risk markers for the development of NAFLD, whereas higher adiponectin values indicated a protection marker.

To investigate the correlation between vitamin B12 and body mass index (BMI) along with insulin resistance (IR) in middle-aged obese women. Materials and methods: The study was designed as a case-control study. The study group included middle-aged obese women and the control group included aged-matched lean women. Weight, height, and hip and waist circumferences were measured. Biochemical parameters such as fasting and postprandial glucose, vitamin B12 and folic acid levels, and lipid profiles were assayed. Results: Enrolled in the study were 116 middle-aged obese and 103 aged-matched healthy lean women. The vitamin B12 level of the obese women was significantly lower than that of the lean women (244.1 ± 131.5 pg/mL vs. 336.2 ± 163.1 pg/mL, P = 0.002). However, there was no significant difference in folic acid levels between the groups (P > 0.05). The vitamin B12 level was similar in the obese women with metabolic syndrome and those without (245.1 ± 145.3 pg/mL vs. 241.2 ± 96.5 pg/mL, P > 0.05), but the level in the control group was significantly higher than that of patients with obesity and metabolic syndrome (P = 0.010 and P = 0.020, respectively). Vitamin B12 levels correlated with BMI (r = –0.259, P = 0.003) but not with IR (r = –0.053, P > 0.05). Conclusion: The vitamin B12 concentration was low in obese patients and this level negatively correlated with BMI, but not with homeostasis model assessment-estimated IR (HOMA-IR).

Background Metabolic syndrome (MS) is a common health problem in menopausal women. According to The Adult Treatment Panel (ATP) III, MS includes the combination of three or more of the following risk factors: abdominal obesity, glucose intolerance, high blood pressure, high serum triglycerides and low levels of high density lipoprotein cholesterol.Objectives To assess the prevalence of the MS in middle-aged women, and the relationships of sociodemographic factors to the MS.Methods This analysis covers 10 766 women born between December 2, 1935 and December 1, 1945, living in the Lund area of Sweden by December 1, 1995.Results We found that 11.6% of women with a mean (±standard deviation) age of 56.9 ± 3.06 years had MS. Women with MS were older and had higher scores for body weight, body mass index, waist/hip ratio, pulse rate, pulse pressure, serum triglycerides and total serum cholesterol (p < 0.001 for all) compared to the control group. More MS women were smokers, less often consumers of alcohol, and less qualified. In addition, they had low-intensity physical activity at leisure time (p < 0.001) and high-intensity physical activity at work (p = 0.009). Premenopausal women and those treated with hormones had less MS (p < 0.001). Education, physical activity at leisure time, moderate intensity of physical activity at work, alcohol intake and smoking had strong association with MS but work status, household status and dietary habits had no significant association with MS.Conclusions Sociodemographic features may contribute to MS. Hence, prevention of MS should encompass sociodemographic features.
