A diagnostic prediction model for hypertension in Han and Yugur population from the China National Health Survey (CNHS).

Background: The prevalence of hypertension is high among Chinese adults, thus, identifying non-hypertensive individuals at high risk for intervention will help to improve the efficiency of primary prevention strategies.

Methods: The cross-sectional data on 9699 participants aged 20 to 80 years were collected from the China National Health Survey in Gansu and Hebei provinces in 2016 to 2017, and they were nonrandomly split into the training set and validation set based on location. Multivariable logistic regression analysis was performed to develop the diagnostic prediction model, which was presented as a nomogram and a website with risk classification.

Association between Serum Uric Acid and Hypertension in Han and Yugur of Gansu Province: The China National Health Survey.

Introduction: Serum uric acid (SUA) has been found correlated with an increased risk of hypertension, but evidence is sparse regarding the association in Gansu Province, especially in Yugur people. This study aimed to explore the nonlinear relationship between SUA levels and hypertension in Han and Yugur people in China.

Methods: The cross-sectional study samples (n = 5,327) were from the China National Health Survey (CNHS) in Gansu Province.

The Additive Interaction between Body Mass Index and Hypertension Family History in Han and Yugur: The China National Health Survey (CNHS).

Objective: To estimate the additive interaction of body mass index (BMI) and family history of hypertension (FHH) on hypertension and explore whether the interaction could be influenced by behavioural risk factors.

Methods: The cross-sectional data on 5791 participants were from the China National Health Survey in Gansu province in 2016. We assessed the additive interaction by calculating the relative excess risk due to interaction (RERI), the attributable proportion due to interaction (AP), and the synergy index (SI).

[Effects of different feeding practices at 0-6 months and living economic conditions on anemia prevalence of infants and young children].

Objective: In order to understand the anemic prevalence in the infants and young children and its relation to the feeding pattern at 0-6 months and on economic income.

Methods: A questionnaire survey were used to collect the information on nutritional and health status of infants and young children (6 to 23 months) living in poverty-rural areas of Gansu Province, and hemoglobin concentration was measured.

Results: The prevalence of anemia was 58.
