ABSTRACT
Background: Many studies have reported the effects of spicy food on human health, but no studies have been conducted on the impact of long-term spicy food consumption on bone mineral density (BMD). This study aimed to investigate the impact of daily consumption of spicy food on BMD in the population aged 50 years and older. Methods: This cross-sectional study was conducted from 2020 to 2022 in Jiangxi Province, China. This study investigated the differences in BMD between non-consumers and daily spicy food consumers in adults aged 50-85 years. A multiple linear regression model was used to investigate the association between spicy food consumption and BMD of the total lumbar spine (LS), femoral neck (FN), and total hip, as well as biochemical markers of bone metabolism (BMBM) levels. Results: The results showed that daily consumption of spicy food was negatively associated with total LS BMD (ß = -0.013, P = 0.015). Subgroup analyses showed this negative association was more pronounced among smokers and drinkers compared to non-smokers (ß: -0.006 vs. -0.042; P for interaction <0.05) and non-drinkers (ß: -0.004 vs. -0.037; P for interaction <0.05). In addition, according to the daily frequency of spicy food consumption, the daily spicy food consumers were categorized into one meal per day, two meals per day, and three meals per day groups. Further analysis revealed that the negative association between spicy food and total LS BMD was progressively stronger as the frequency of daily consumption of spicy food increased (P for trend <0.05). For BMBM, daily consumption of spicy food was positively associated with serum PINP levels and negatively associated with serum Ca and serum Mg levels. Conclusions: Our study suggested that daily consumption of spicy food was associated with lower LS BMD in middle-aged and older Chinese adults, and this association was more pronounced in the smoking and drinking populations. The adverse effects of spicy food on LS BMD become progressively stronger with increasing frequency of daily consumption of spicy food. In addition, daily consumption of spicy food was associated with higher PINP levels and lower serum Ca and Mg levels.

Background: Osteoporosis has already been a growing health concern worldwide. The influence of living area, lifestyle, socioeconomic, and medical conditions on the occurrence of osteoporosis in the middle-aged and elderly people in China has not been fully addressed. Methods: The study was a multicenter cross-sectional study on the middle-aged and elderly permanent residents, which gathered information of 22,081 residents from June 2015 to August 2021 in seven representative regions of China. The bone mineral density of lumbar vertebrae and hip were determined using the dual-energy X-ray absorptiometry densitometer instruments. Serum levels of bone metabolism markers were also measured. Information about education, smoking, and chronic diseases were also collected through face-to-face interviews. Age-standardized prevalence and 95% confidence intervals (CIs) of osteopenia and osteoporosis by various criteria were estimated by subgroups and overall based on the data of China 2010 census. The relationships between the osteoporosis or osteopenia and sociodemographic variables or other factors were examined using univariate linear models and multivariable multinomial logit analyses. Results: After screening, 19,848 participants (90%) were enrolled for the final analysis. The age-standardized prevalence of osteoporosis was estimated to be 33.49%(95%CI, 32.80-34.18%) in the middle-aged and elderly Chinese permanent residents, for men and women was 20.73% (95% CI, 19.58-21.87%) and 38.05% (95% CI, 37.22-38.89%), respectively. The serum concentrations of bone metabolic markers, and calcium and phosphorus metabolism were influenced by age, body mass index (BMI), gender, education level, regions, and bone mass status. Women, aged 60 or above, BMI lower than 18.5 kg/m2, low education level including middle school, primary school and no formal education as well as current regular smoking, a history of fracture were all significantly associated with a higher risk of osteoporosis and osteopenia in the middle-aged and elderly people. Conclusions: This study revealed dramatic regional differences in osteoporosis prevalence in China, and female, aged 60 or older, low BMI, low education level, current regular smoking, and a history of fracture were associated with a high risk of osteoporosis. More prevention and treatment resources should be invested into particular population exposed to these risk factors.

Introduction: The correlation between the non-use of cooking oil fumes (COFs) extractors and bone mineral density (BMD) have not been clarified. Consequently, this study attempted to explore the impact of non-use COFs extractors on BMD in population aged 45 years and older based on a cross-sectional study. Methods: This study was a cross-sectional study within the framework of an ongoing prospective population-based cohort study in China. The multivariate linear regression models were used to evaluate the correlation between the non-use of fume extractors in family cooking and total lumbar spine (LS), femoral neck (FN), total hip BMD and levels of bone metabolism markers. Results: A total of 3433 participants were included in the final analyses, of which 2607 (75.93%) participants used fume extractors. The results of models indicated that there were significant correlations of the non-use of fume extractors on total LS BMD (ß = -0.024, 95% CI, -0.036, -0.012, p < 0.001), PINP (ß = 4.363, 95% CI, 2.371, 6.356, p < 0.001) and ALP (ß = 4.555, 95% CI, 2.593, 6.517, p < 0.001) levels. Conclusions: This study verified that the use of fume extractors is an efficacious measure to prevent LS bone loss. For the sake of public bone health, people should install a fume extractor in the kitchen and use it routinely when cooking.
