Association between Bell's Palsy and Cardiometabolic Risks: An Age- and Sex-Matched Case-Control Study

BACKGROUND

Bell's palsy is possibly an ischemic cranial neuropathy, although reactivation of herpes virus infection has been proposed.

METHODS

This was an age-and sex-matched and 1:2 case-control study enrolling Bell's palsy patients during 2011-2021 in a university hospital to investigate the significant associations of cardiometabolic risks (CMRs) with Bell's palsy. We analyzed the differences in waist circumference (WC), body mass index (BMI), systolic and diastolic blood pressures (SBP and DBP), fasting blood sugar (FBS), and lipid levels at 12 weeks post-Bell's palsy with those of the controls by descriptive statistics (p < 0.05). The differences in means or medians of individual CMR values across the consecutive 10-year age intervals were analyzed by ANOVA F-tests and Kruskal-Wallis tests (p < 0.05).

RESULTS

A total of 140 cases and 280 controls were enrolled. Bell's palsy patients had significantly higher WC, BMI, SBP, DBP, FBS, and triglyceride but lower high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Moreover, high WC, elevated FBS (≥100 mg/dL), SBP (≥130 mmHg), and total cholesterol were significantly associated with Bell's palsy cases by multivariable analysis. Only FBS in Bell's palsy patients significantly elevated across consecutive 10-year age intervals.

CONCLUSION

Screening and monitoring for CMRs, especially hyperglycemia, in every patient presenting with Bell's palsy is essential despite initial normoglycemia, particularly in older-onset cases.

Cardiometabolic risk factors in South American children: A systematic review and meta-analysis

BACKGROUND

Cardiometabolic risk factors (impaired fasting glucose, abdominal obesity, high blood pressure, dyslipidemia) cluster in children, may predict adult disease burden, and are inadequately characterized in South American children.

OBJECTIVES

To quantify the burden of cardiometabolic risk factors in South American children (0-21 years) and identify knowledge gaps.

METHODS

We systematically searched PubMed, Google Scholar, and the Latin American and Caribbean Health Sciences Literature via Virtual Health Library from 2000-2021 in any language. Two independent reviewers screened and extracted all data.

RESULTS

179 studies of 2,181 screened were included representing 10 countries (n = 2,975,261). 12.2% of South American children experienced obesity, 21.9% elevated waist circumference, 3.0% elevated fasting glucose, 18.1% high triglycerides, 29.6% low HDL cholesterol, and 8.6% high blood pressure. Cardiometabolic risk factor definitions varied widely. Chile exhibited the highest prevalence of obesity/overweight, low HDL, and impaired fasting glucose. Ecuador exhibited the highest prevalence of elevated blood pressure. Rural setting (vs. urban or mixed) and indigenous origin protected against most cardiometabolic risk factors.

CONCLUSIONS

South American children experience high rates of obesity, overweight, and dyslipidemia. International consensus on cardiometabolic risk factor definitions for children will lead to improved diagnosis of cardiometabolic risk factors in this population, and future research should ensure inclusion of unreported countries and increased representation of indigenous populations.
