Secondhand smoke exposure and dyslipidemia among non-smoking adults in the United States.

Dyslipidemia is a major public health challenge worldwide and whether secondhand smoke exposure (SHSE) is associated with dyslipidemia is yet to be understood. This study evaluated the relationship between SHSE and odds of dyslipidemia among adults in the United States. We identified 3064 adults who had never smoked in the 2015-2016 National Health and Nutrition Examination Survey and estimated the odds ratio and 95% confidence interval for the relationship between SHSE and odds of dyslipidemia using a multivariable adjusted-logistic regression at a two-sided p < 0.05. Overall, the mean age of respondents was 46.4 ± 18.0 years, 59.6% had dyslipidemia and 36.2% had SHSE. The odds of dyslipidemia among individuals with SHSE were 1.148 (1.147, 1.149) in the overall sample, 1.214 (1.214, 1.215) among women and 1.165 (1.163, 1.167) among men. The odds trended similarly independent of age groups: 1.130 (1.129, 1.131) for young adults (<60 years) and 1.304 (1.300, 1.308) for old adults (≥60 years). SHSE was associated with higher odds of dyslipidemia with higher odds among women and old adults. Primary intervention(s) targeted at reducing SHSE may show benefits in reducing the odds of dyslipidemia, and longitudinal studies would be necessary to clarify the association between SHSE and dyslipidemia.

Association of Environmental tobacco smoke exposure with depression among non-smoking adults.

BACKGROUND: Depression is a psychological dysfunction that impairs health and quality of life. However, whether environmental tobacco smoke exposure (ETSE) is associated with depression is poorly understood. This study was designed to evaluate the association of ETSE with depression among non-smoking adults in the United States. METHOD: Using the 2015-2016 United States National Health and Nutrition Examination Survey (NHANES), we identified 2623 adults (females - 64.2%, males - 35.8%) who had never smoked and applied multivariable adjusted-logistic regression to determine the adjusted odds ratio (aOR) and 95% confidence interval (CI) at P < 0.05 for the association of ETSE with depression adjusting for relevant confounders. RESULTS: Mean age of respondents was 46.5 ± 17.9 years, 23.5% reported ETSE, and 4.7% reported depression. Also, aORs for the association of ETSE with depression were 1.992 (1.987, 1.997) among females and 0.674 (0.670, 0.677) among males. When we examined the association by age groups, the aORs were 1.792 (1.787, 1.796) among young adults (< 60 years) and 1.146 (1.140, 1.152) among older adults (≥60 years). CONCLUSIONS: We found that ETSE was associated with higher odds of depression among females but not among males.

Passive smoking exposure and the risk of hypertension among non-smoking adults: the 2015-2016 NHANES data.

BACKGROUND: Hypertension is a major public health problem and a prominent risk factor for cardiovascular diseases. However, whether passive smoking exposure (PSE) is associated with the risk of hypertension is scarcely understood. This study assessed the association between PSE and the risk of hypertension among adults (≥18 years) in the United States of America. METHODS: Three thousand and sixty-seven adults were identified from the 2015-2016 National Health and Nutrition Examination Survey and the association between PSE and hypertension (adjusting for relevant confounders) was examined using multivariable adjusted-logistic regression analysis at P < 0.05. RESULTS: Mean age of respondents was 46.5 ± 17.9 years. Overall, 23.7% of respondents reported PSE and 32.6% were hypertensives (of which only 14.3% were aware of their hypertensive state) Also, adjusted odds of hypertension for participants with PSE was 1.038 (1.037, 1.040), P < 0.0001, in the overall population. Also, PSE aggravated odds of hypertension among young adults - < 60 years (aOR: 1.095, 95CI%: 1.094 to 1.097), P < 0.0001, and old adults - ≥60 years (aOR: 1.110, 95% CI: 1.108 to 1.113), P < 0.0001. Similarly, PSE was associated with increased odds of hypertension among women (aOR: 1.240, 95% CI: 1.238 to 1.242), P < 0.0001 but not among men (aOR: 0.755, 95% CI: 0.754 to 0.757), P < 0.0001. CONCLUSIONS: PSE was independently associated with the risk of hypertension particularly among women, young and old adults. A multi-ethnic longitudinal cohort may help ascertain causality and provide more evidence for appropriate interventions.
