[Epidemiological characteristics and influencing factors of diabetes and pre-diabetes among adult residents in Hainan Province].

Objective

To describe epidemiological characteristics and their influencing factors of diabetes and pre-diabetes among adult residents in Hainan Province and provide a theoretical basis to develop epidemic prevention and control strategies for diabetes.

Methods

This study used a two-stage unequal proportion cluster sampling method, and 32 857 subjects (≥18 years old) were collected from 24 cities/counties/districts in Hainan Province. All the subjects were investigated with questionnaires, physical examination, and laboratory tests from January to June 2023. The χ2 and Mantel-Haenszel trend χ2 tests were used to analyze the data. Multivariate logistic regression was used to analyze the factors influencing diabetes and pre-diabetes. SPSS 23.0 software was used to analyze the data.

Results

The crude prevalence of diabetes and pre-diabetes in adult residents of Hainan Province were 18.1% and 22.8%, while the weighted rates were 13.7% and 20.7%, respectively. The results of multivariate logistic regression analysis showed that: aging (30-39 years old: OR=2.65, 95%CI: 2.06-3.41; 40-49 years old: OR=5.64, 95%CI: 4.40-7.24; 50- 59 years old: OR=9.88, 95%CI: 7.71-12.67; 60-69 years old: OR=18.34, 95%CI: 14.28-23.55; 70-79 years old: OR=21.30, 95%CI: 16.41-27.65; 80 years old and above: OR=24.13, 95%CI: 17.94-32.46), nationality (Li minority group: OR=1.50, 95%CI: 1.38-1.63; other ethnic groups: OR=1.53, 95%CI: 1.20-1.94), urban (OR=1.12, 95%CI: 1.04-1.21), central obesity (OR=2.14, 95%CI: 2.01-2.29), higher frequency of alcohol consumption (5-7 day/week: OR=1.24, 95%CI: 1.11-1.38), physical inactivity (OR=1.09, 95%CI: 1.02-1.17) were risk factors for diabetes, while aging (30-39 years old: OR=1.53, 95%CI: 1.31-1.79; 40-49 years old: OR=2.36, 95%CI: 2.01-2.76; 50-59 years old: OR=3.03, 95%CI: 2.58-3.55; 60-69 years old: OR=4.22, 95%CI: 3.58-4.97; 70-79 years old: OR=5.05, 95%CI: 4.23-6.04; 80 years old and above: OR=6.08, 95%CI: 4.86-7.61), nationality: (Li minority group: OR=1.18, 95%CI: 1.10-1.28; other ethnic groups: OR=1.40, 95%CI: 1.14-1.71), urban (OR=1.12, 95%CI: 1.04-1.19), central obesity (OR=1.72, 95%CI: 1.62-1.83), higher frequency of alcohol consumption (1-4 day/week: OR=1.12, 95%CI: 1.01-1.23; 5-7 day/week: OR=1.35, 95%CI: 1.22-1.49) were risk factors for pre-diabetes.

Conclusions

The epidemic situation of diabetes and pre-diabetes among adult residents in Hainan Province was not optimistic. In order to control the development of abnormal blood glucose, measures and targeted health education should be carried out to strengthen the screening, treatment, and management of people with abnormal blood glucose among different populations.
