“…Of note, Ganie et al 36 investigated 320 healthy participants and 144 women with polycystic ovary syndrome (PCOS), both groups separated by diet (vegetarian vs. non-vegetarian). Hung et al 23 and Lee et al 27 conducted the study in a mixed population of apparently healthy participants and patients with metabolic syndrome (less than 20% of the study population). Moreover, six studies were conducted in participants diagnosed with impaired kidney function 26 , 30 , 32 , 35 , type 2 diabetes 31 or PCOS 36 .…”

“…Last, sensitivity analysis for study quality was performed to investigate single studies as potential sources of heterogeneity including study quality score (< 6 or ≥ 6 stars), continents (Asia, Europe, South America) and duration of vegetarian diet (< 10 or ≥ 10 years). Of note, for Hung et al 23 and Ganie et al 36 the last classification was not possible, due to missing information on duration of vegetarian diet. Meta‐regression analyses were performed examine whether there were differences in inflammatory biomarkers between dietary groups, controlling for BMI (mean BMI or difference of BMI between diet groups).…”

Plant-based diets like vegetarian or vegan diets might influence circulating levels of inflammatory biomarkers, thereby reducing the risk of chronic diseases. This systematic review and meta-analysis aimed to investigate the associations of veganism and vegetarianism with circulating inflammatory biomarkers in comparison to omnivores. Literature search was conducted in Pubmed and EMBASE until April 2020 and mean differences of biomarkers were assessed for: C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-18 (IL-18), interleukin-1 receptor antagonist (IL-1 RA), tumor necrosis factor-alpha (TNF-ɑ), E-selectin, intercellular adhesion molecule-1 (ICAM-1), monocyte chemoattractant protein-1 (MCP-1), adiponectin, omentin-1 and resistin. Of initially identified 1073 publications, 21 cross-sectional studies met the inclusion criteria and were included in the systematic review and meta-analysis. Vegan diet was associated with lower levels of CRP compared to omnivores [mean difference − 0.54 mg/l, 95%-CI: − 0.79 to − 0.28, p < 0.0001]. This association was less pronounced in vegetarians [mean difference − 0.25 mg/l, 95%-CI: − 0.49 to 0.00, p = 0.05]. In patients with impaired kidney function, the association between vegetarian nutrition and CRP was much stronger with − 3.91 mg/l (95%-CI: − 5.23 to − 2.60; p < 0.0001). No substantial effects were observed for all other inflammatory biomarkers. Despite strong associations between CRP and a vegan or vegetarian diet were seen, further research is needed, as most inflammatory biomarkers were investigated only in single studies so far.

“…Notably, the prevalence of MetS in Malaysian vegetarians was lower than the Korean postmenopausal vegetarians (33.9%) [ 13 ], and US vegetarians (25.2%) [ 11 ], but higher than the Taiwanese vegetarians (13.3%) [ 12 ]. The discrepancies in prevalence could be due to the different MetS criteria used by these studies [ 11 , 12 , 13 , 14 , 31 ]. The present study showed that high BP (48.7%) and large WC (43.6%) were found to be the most common MetS components among the vegetarians.…”

“…Despite the prevalence of MetS has been reported [ 11 , 12 , 13 , 14 ], factors that contribute to the development of MetS in vegetarians remain unknown. The present study showed that vegetarians who were overweight and obese had higher odds for MetS compared to those who were underweight and with normal weight, and this observation remained significant after adjustments have been made for sex and age in the multiple logistic regression analysis.…”

“…Likewise, postmenopausal vegetarians had a lower risk of MetS (33.9%) than non-vegetarians (47.9%) in Korea [ 13 ]. The existing studies, which compared the prevalence of MetS between vegetarians and non-vegetarians found that vegetarians had lower prevalence of MetS than non-vegetarians [ 11 , 12 , 13 , 14 ]. Despite the lower prevalence of MetS in vegetarians than non-vegetarians, the MetS issues in vegetarians (6.7–33.9%) [ 11 , 12 , 13 , 14 ] should not be neglected.…”

The prevalence and factors associated with metabolic syndrome (MetS) remain unknown in Malaysian vegetarians. This cross-sectional study aimed to determine the prevalence of MetS among vegetarians in Kuala Lumpur and Selangor and its associated factors. The data on socio-demographic characteristics, vegetarianism practises, lifestyle behaviours, body weight, height, waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), and blood lipid profiles were collected from 273 vegetarians. A majority of the respondents were lacto-ovo vegetarians (44.0%), females (64.8%) and Chinese (54.9%). The prevalence of MetS was 24.2%. High BP (48.7%) and high WC (43.6%) were the most common MetS components. Females had lower WC, SBP, DBP, FBG, TG and higher HDL-c (p < 0.05) as compared to males. Multiple logistic regression analysis showed that being overweight and obese (Odds Ratio (OR) = 7.74, 95% Confidence Interval (CI): 4.04–14.82) was the main risk factor of MetS after being adjusted for sex and age. This study found that one in four vegetarians had MetS. An intervention programme should be developed to reduce Body Mass Index (BMI) among vegetarians, especially among those who are found to be overweight and obese.

Effect of vegetarian diets on the presentation of metabolic syndrome or its components: A systematic review and meta-analysis

VD in comparison with omnivorous diet is not associated with a lower risk of MetS based on results of meta-analysis of cross-sectional studies. The association between VD and lower levels of SBP, DBP, HDL-C, and fasting glucose is uncertain due to high heterogeneity across the cross-sectional studies. Larger and controlled studies are needed to evaluate the association between VD and MetS and its components.
