OBJECTIVES: This study aimed to investigate the associations of obesity phenotypes with hypertension stages, phenotypes, and transitions among middle-aged and older Chinese. METHODS: Using the 2011-2015 waves of the China Health and Retirement Longitudinal Study, we conducted a cross-sectional analysis included 9,015 subjects and a longitudinal analysis included 4,961 subjects, with 4,872 having full data on the hypertension stage and 4,784 having full data on the hypertension phenotype. Based on body mass index and waist circumstance, subjects were categorized into 4 mutually exclusive obesity phenotypes: normal weight with no central obesity (NWNCO), abnormal weight with no central obesity (AWNCO), normal weight with central obesity (NWCO), and abnormal weight with central obesity (AWCO). Hypertension stages were classified into normotension, pre-hypertension, stage 1 hypertension, and stage 2 hypertension. Hypertension phenotypes were categorized as normotension, pre-hypertension, isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic-diastolic hypertension (SDH). The association between obesity phenotypes and hypertension was estimated by logistic regression. A comparison between different sexes was conducted by testing the interaction effect of sex. RESULTS: NWCO was associated with normal→stage 2 (odds ratio [OR], 1.95; 95% confidence interval [CI], 1.11 to 3.42), maintained stage 1 (OR, 1.62; 95% CI, 1.14 to 2.29), and normal→ISH (OR, 1.39; 95% CI, 1.05 to 1.85). AWCO was associated with normal→stage 1 (OR, 1.75; 95% CI, 1.40 to 2.19), maintained stage 1 (OR, 2.77; 95% CI, 2.06 to 3.72), maintained stage 2 (OR, 2.80; 95% CI, 1.50 to 5.25), normal→ISH (OR, 1.56; 95% CI, 1.20 to 2.02), and normal→SDH (OR, 2.54; 95% CI, 1.72 to 3.75). An interaction effect of sex existed in the association between obesity phenotypes and hypertension stages. CONCLUSIONS: This study highlights the importance of various obesity phenotypes and sex differences in hypertension progression. Tailored interventions for different obesity phenotypes may be warranted in hypertension management, taking into account sex-specific differences to improve outcomes.

Browning is one of the key factors that influenced the callus subculture of tree peony (Paeonia suffruticosa Andr.). Effects of medium composition and exogenous hormones: macro elements of Murashige and Skoog (MS salts) and iron salt (Fe2+), pH, agar and 6-benzylaminopurine (6-BA), 1-naphthaleneacetic acid (NAA) and kinetin (KT) on the callus browning of P. suffruticosa ‘Shan Hu Tai’ in vitro were studied in this paper. Results showed that the browning of P. suffruticosa callus were more sensitive to KT than 6-BA in different concentrations of 6-BA and KT separately with different concentrations of NAA, and reduced to the lowest (13.3%) under 0.5 mg·L-1 NAA plus 0.3 mg·L-1 KT. 1/4 × MS plus 1/4 × Fe2+ was the best basic medium in which the browning rate was only 18.2%. The browning rate of the callus was the lowest of 4.0% under pH 6.5 and the callus grew better in 7.0 g·L-1 agar than others. This study indicated that the best medium preventing P. suffruticosa callus in vitro from browning was: 1/4 × MS medium supplemented with 6.95 mg·L-1Fe2+, 0.3 mg·L-1 KT, 0.5 mg·L-1 NAA, 6.0 g·L-1 agar and 30 g·L-1 sucrose in pH 6.5.
