Association between lifestyle and metabolic syndrome incidence of workers in northern Okinawa, Japan: A cohort study

Impact of Changes in Lifestyle and Psychological Factors on the Incidence of Metabolic Syndrome after the Great East Japan Earthquake: Follow-up of the Fukushima Health Management Survey

AIM

The Fukushima Daiichi Nuclear Power Plant accident caused lifestyle changes and psychological distress in residents living near the plant. This study clarified the associations between changes in residents' lifestyles and psychological factors with the onset of metabolic syndrome (METs) after the accident.

METHODS

This longitudinal study included 10,373 residents who underwent the Comprehensive Health Check and Mental Health and Lifestyle Survey in Fiscal Year (FY) 2013. Follow-up surveys were conducted between FY 2014 and FY 2017. Lifestyle changes and the METs incidence were evaluated using a logistic regression model.

RESULTS

METs developed in 14.0% of subjects. In addition to metabolic factors, such as the body mass index, hypertension, dyslipidemia, and diabetes mellitus, there were differences in physical activity, fast walking, eating fast, eating habits before bedtime, skipping breakfast, current smoking, and alcohol intake between subjects with and without new-onset METs. Eating fast, current smoking, and drinking alcohol were positively associated with new-onset METs, whereas starting physical activity and fast walking were inversely associated with new-onset METs.

CONCLUSIONS

Disaster-related lifestyle changes, such as eating fast, starting to smoke, and continued alcohol intake, were risk factors for new-onset METs after the Fukushima Daiichi Nuclear Power Plant accident.

The impact of breakfast skipping on plasma glucose levels in non-diabetic individuals: gender-based differences and implications

Chrono-nutritional factors may play a significant role in glucose regulation and the risk of type 2 diabetes (T2D). We investigated the association between breakfast skipping (BS) and fasting plasma glucose (FPG) levels in a non-diabetic cohort of the ABCD project (nutrition, cardiovascular wellness and diabetes) representing the general population of Palermo, Italy Among the 623 participants included in the analysis, 118 individuals were identified as BS. In men, BS was associated with higher values of FPG (p < .05), glycated haemoglobin (p < .01), triglycerides (p < .05) and insulin (p < .005). Among women, no significant differences were observed between BS and non-skippers. Multivariate regression analysis confirmed that BS was an independent predictor of higher FPG levels in men (p < .01); waist circumference emerged as the primary predictor of FPG in women (p < .001). This study supports the importance of dietary habits in glycaemic control and T2D risk.

Metabolic syndrome risk in adult coffee drinkers with the rs301 variant of the LPL gene

BACKGROUND

Metabolic syndrome (MetS), a cluster of metabolic and cardiovascular risk factors is influenced by environmental, lifestyle, and genetic factors. We explored whether coffee consumption and the rs301 variant of the lipoprotein lipase (LPL) gene are related to MetS.

METHODS

We conducted multiple logistic regression analyses using data gathered from 9523 subjects in Taiwan Biobank (TWB).

RESULTS

Our findings indicated that individuals who consumed coffee had a reduced odds ratio (OR) for MetS (0.750 (95% confidence interval [CI] 0.653-0.861) compared to non-coffee drinkers. Additionally, the risk of MetS was lower for individuals with the 'TC' and 'CC' genotypes of rs301 compared to those with the 'TT' genotype. Specifically, the OR for MetS was 0.827 (95% CI 0.721-0.949) for the 'TC' genotype and 0.848 (95% CI 0.610-1.177) for the 'CC' genotype. We observed an interaction between coffee consumption and the rs301 variant, with a p-value for the interaction of 0.0437. Compared to the reference group ('no coffee drinking/TT'), the ORs for MetS were 0.836 (95% CI 0.706-0.992) for 'coffee drinking/TT', 0.557 (95% CI 0.438-0.707) for 'coffee drinking/TC', and 0.544 (95% CI 0.319-0.927) for 'coffee drinking/CC'. Notably, MetS was not observed in non-coffee drinkers regardless of their rs301 genotype.

CONCLUSION

Our findings suggest that rs301 genotypes may protect against MetS in Taiwanese adults who consume coffee compared to non-coffee drinkers.
