Association of metabolic syndrome with mobility in the older adults: a Korean nationwide representative cross-sectional study

Examining determinants of control of metabolic syndrome among older adults with NCDs receiving service at NCD Plus clinics: multilevel analysis

BACKGROUND

Metabolic syndrome (MetS) in older adults with hypertension, diabetes, and hyperlipidemia increases the risks of cardiovascular diseases by 2.5 times and type 2 diabetes by five times. This study aimed to explain the multilevel relationships between health service system factors and individual-level factors influencing the control of MetS among older adults with NCDs receiving health care services at the NCD Plus clinics of hospitals in 1 year.

METHODS

This cross-sectional analytical study employed a systematic sampling method to have two groups of samples from 4 regions of Thailand: (1) 600 older adults having at least one diagnosis of NCDs receiving services at NCD Plus clinics and (2) 12 nurses in charge of the NCD Plus clinics at the hospitals providing services to these patient samples. Data were analyzed using multilevel logistic regression analysis.

RESULTS

24% of older adults with NCDs can control MetS within one year. The MetS escalation from the initial assessment to 1-year follow-up varied according to the level of the hospitals. The transition from MetS to non-MetS status was rare in older adults with NCDs. Among health service system factors, complete screening for MetS influenced 1-year MetS control (95% CI [1.06, 2.92]). Older adults who were female and who had polypharmacy had a 66% (95% CI [0.22, 0.53]) and a 54% (95% CI [0.29 - 0.71]) reduction chance in MetS control. Older adults, who were ≥ 80 years old, labor-employed, healthy dietary patterns, and medication adherence increased chances of controlling MetS by 2.38 times (95% CI [1.12, 5.05]), 2.14 times (95% CI [1.03, 4.42]), 1.61 times (95% CI [1.06-2.46]), and 3.18 times (95% CI [1.51, 6.70]), respectively.

CONCLUSIONS

NCDs Plus clinics that provide complete screening for MetS significantly enhance their effectiveness in reducing the proportion of older adults with MetS. In addition, the service should pay attention to older adults who are female, are retired, and take multiple medications to achieve MetS control better. The insights gained from such an analysis could be instrumental in pinpointing the resources necessary to bolster the efficacy of NCD Plus clinics.

Semiparametric modeling for the cardiometabolic risk index and individual risk factors in the older adult population: A novel proposal

The accurate monitoring of metabolic syndrome in older adults is relevant in terms of its early detection, and its management. This study aimed at proposing a novel semiparametric modeling for a cardiometabolic risk index (CMRI) and individual risk factors in older adults.

METHODS

Multivariate semiparametric regression models were used to study the association between the CMRI with the individual risk factors, which was achieved using secondary analysis the data from the SABE study (Survey on Health, Well-Being, and Aging in Colombia, 2015).

RESULTS

The risk factors were selected through a stepwise procedure. The covariates included showed evidence of non-linear relationships with the CMRI, revealing non-linear interactions between: BMI and age (p< 0.00); arm and calf circumferences (p<0.00); age and females (p<0.00); walking speed and joint pain (p<0.02); and arm circumference and joint pain (p<0.00).

CONCLUSIONS

Semiparametric modeling explained 24.5% of the observed deviance, which was higher than the 18.2% explained by the linear model.

Association between Cardiorespiratory Fitness and Metabolic Syndrome in Korean Older Adults

BACKGROUND

Little is known about the relationship between non-exercise-based estimation of cardiorespiratory fitness (eCRF) and metabolic syndrome (MetS) in Korea. The current study examined the prognostic role of eCRF in the risk stratification of MetS in a representative sample of Korean older adults (1822 men and 3069 women).

METHODS

The data used in the current study were extracted from the Korea National Health and Nutrition Examination Surveys IV and V. eCRF was obtained using a previously validated algorithm. MetS was defined according to the National Cholesterol Education Program definition with the acceptance of a Korean-specific waist circumference cutoff point.

RESULTS

Lower eCRF was significantly correlated with abnormalities in several components of MetS, including abdominal obesity, elevated glucose, elevated triglycerides, and decreased high-density lipoprotein cholesterol. Furthermore, there was an inverse linear relationship between MetS prevalence and eCRF levels; higher eCRF was significantly and independently associated with lower prevalence of MetS.

CONCLUSION

The current findings suggest that eCRF can be adopted as a prognostic measure in determining the risk for MetS for elderly persons.
