Introduction: Our previous cross-sectional study revealed the association between neck circumference (NC) and hyperuricemia. This study aimed to further investigate the longitudinal association between NC and hyperuricemia and to compare the strengths of longitudinal association of NC and waist circumference (WC) with hyperuricemia. Methods: A total of 4383 subjects without hyperuricemia at baseline were included. Multivariable linear regression was used to assess the association between baseline anthropometric indices and uric acid level at follow-up. Cox regression was used to assess the relationship between baseline anthropometric indices and the risk of future hyperuricemia. A receiver-operating characteristic curve was used to compare the predictive ability of baseline anthropometric indices for future hyperuricemia. Results: Among women, only baseline NC was positively, linearly associated with uric acid level at follow-up (β = 1.75) and risk of future hyperuricemia (ptrend < 0.05); risk of hyperuricemia in the third and fourth quartile groups of baseline NC significantly increased, compared with the first quartile group of baseline NC (HR = 1.48 and 1.81, respectively). Among men, neither NC nor WC was associated with hyperuricemia after adjusting for confounder factors. The area under the curve of baseline NC and WC for hyperuricemia was comparable in both genders (0.606 for NC and 0.599 for WC in women, 0.578 for NC and 0.602 for WC in men). Conclusions: For women, only baseline NC is an independent risk factor of hyperuricemia within 3 years. NC and WC have a similar 3-year predictive ability for hyperuricemia in both genders. Key Points • This is the first study to assess the longitudinal association between neck circumference and hyperuricemia. • According to the results of this study, we propose for the first time that neck circumference is an independent risk factor for hyperuricemia in women in the future, rather than waist circumference. • We found for the first time that neck circumference and waist circumference have similar predictive ability for future hyperuricemia in both genders.

The aim of present study was to explore the relationships between osteopenia and dyslipidemia, glycemic levels or blood pressure in postmenopausal Chinese women. A total of 4080 women aged 42-85 years were enrolled in this cross-sectional study, which was nested in an ongoing longitudinal (REACTION) study. Calcaneus quantitative ultrasound (QUS) was performed and QUS T score was calculated to assess bone mineral density. Osteopenia was defined as a T score ≤−1.0. The relationship between osteopenia and dyslipidemia, glycemic levels or blood pressure was investigated. The prevalence of osteopenia was significantly lower in subjects with systolic blood pressure (SBP) ≥140 mmHg, fasting blood glucose (FBG) ≥8.0 mmol/L, postprandial blood glucose (PBG) ≥15.0 mmol/L, hemoglobin A1c (HbA1C) 6.5-7.5 %, HbA1C ≥7.5 %. These relationships remained significant after controlling for multiple factors. Moreover, significant trend between osteopenia and SBP, FBG, PBG and HbA1C was observed in women. In contrast, no significant associations between osteopenia and diastolic blood pressure (DBP), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) were found, and no significant trend relationship between osteopenia and DBP, TC, TG, HDL-C, LDL-C was found in postmenopausal Chinese women. The present study showed a relationship between SBP, FBG, PBG, HbA1C and osteopenia in postmenopausal Chinese women, while no significant relationship was observed between dyslipidemia, DBP and osteopenia, even after controlling for multiple confounding factors.
