This study examined factors influencing cumulative lead burden in male veterans, utilizing bone lead measurements via K-shell X-ray fluorescence. Findings indicated that age, occupational exposure, and lifestyle factors such as smoking were significant predictors of elevated bone lead levels. The research underscores the importance of considering these variables when assessing
This multicenter retrospective cohort study analyzed 611 patients who remained cancer-free for at least two years following treatment for histologically confirmed small-cell lung cancer (SCLC). The study assessed the incidence of second primary cancers (SPCs) in this population. Findings revealed that the overall risk of SPCs was 3.5 times higher
This 2018 study analyzed data from NHANES III (1988–1994) and NHANES IV (2007–2010) to assess shifts in biological aging among U.S. adults. Findings indicated that biological age decreased over time, particularly among older adults and males. These improvements were partially attributed to changes in modifiable behaviors such as reduced smoking
This pooled analysis of over 34,000 U.S. adults from NHANES III (1988–1994) and continuous NHANES (1999–2006) examined associations between serum levels of antioxidant vitamins (A, C, D, α- and γ-tocopherol) and respiratory health outcomes. Lower serum vitamin C was linked to increased odds of wheeze (aOR: 1.08), and among smokers,
This cohort study examined the effect of lifestyle factors like smoking, diet, coffee, and alcohol consumption on plasma total homocysteine (tHcy) concentrations in individuals with different MTHFR C677T genotypes. It found that smoking and poor diet were linked to higher tHcy levels, with beer consumption associated with lower tHcy, particularly
This cohort study examined how lifestyle factors, such as smoking, alcohol consumption, and physical activity, interact with MTHFR C677T gene polymorphisms to affect homocysteine (Hcy) levels in young adults from the Pelotas Birth Cohort. The study, which included 3,803 participants, found that individuals with the MTHFR C677T polymorphism, particularly those
This 2013 observational study published in PLoS One (DOI: 10.1371/journal.pone.0067833) analyzed data from 9,895 U.S. adults in the NHANES survey to assess how lifestyle factors impact inflammation, as measured by high-sensitivity C-reactive protein (hsCRP), and how these effects vary by BMI. The study found that in normal weight and overweight
This observational study, published in Atherosclerosis (DOI: 10.1016/s0021-9150(02)00380-5), explored the relationship between plasma high-sensitivity C-reactive protein (hsCRP) levels and traditional cardiovascular risk factors in 908 participants aged 30-79. The study found that hsCRP levels were significantly higher in individuals with hypertension, diabetes, or coronary artery disease, and multiple regression analysis
This cross-sectional study analyzed factors associated with inflammation markers in healthy women, finding significant correlations between higher BMI, smoking, physical inactivity, and elevated levels of C-reactive protein (CRP) and other inflammatory biomarkers. These results highlight the role of lifestyle and body composition in systemic inflammation, underscoring the importance of weight
This observational study examined associations between various demographic, lifestyle, and dietary factors and systemic inflammation markers in adults aged 50–76 years. Higher age and BMI were linked to increased levels of most inflammation markers, while physical activity, dietary vitamin C, fiber intake, and omega-3 fatty acids were associated with lower
