Abstract:
Objective:To investigate the knowledge, attitudes and practice related to salt reduction among residents in Xicheng District, Beijing Municipality, and to analyze the influencing factors of salt reduction practice, so as to provide the evidence for formulating salt reduction strategies.
Methods:In July 2023, permanent residents aged 18-79 years in Xicheng District were selected using the multistage stratified random sampling method and probability proportionate to size sampling method. Data on demographic information, history of chronic diseases, salt intake, as well as knowledge, attitudes, and practices regarding salt reduction were collected through questionnaire surveys. The residents' salt intake excess rate, salt reduction awareness rate, salt reduction attitudes support rate, and salt reduction practice rate were analyzed. The influencing factors of salt reduction practice were analyzed by a multivariable logistic regression model.
Results:Totally 6 360 questionnaires were allocated, and 6 211 valid questionnaires were recovered, with an effective recovery rate of 97.66%. Among the respondents, 3 022 (48.66%) were males and 3 189 (51.34%) were females, with a mean age of (46.80±15.10) years. Excessive salt intake was identified in 2 111 individuals, with an excess rate of 33.99%. Knowledge awareness of salt reduction was observed in 4 187 participants, with an awareness rate of 67.41%. Supportive attitudes were reported by 5 636 participants, with a support rate of 90.74%. And salt reduction practices were adopted by 3 152 participants, with a practice rate of 50.75%. The multivariable logistic regression analysis revealed that female (OR=1.397, 95%CI: 1.257-1.553), aged 40-79 years (40-<60 years, OR=1.290, 95%CI: 1.141-1.459; 60-79 years, OR=1.301, 95%CI: 1.114-1.519, having chronic diseases (OR=1.826, 95%CI: 1.582-2.108), awareness of salt reduction (OR=1.695, 95%CI: 1.511-1.901), and a supportive attitude towards salt reduction (OR=6.235, 95%CI: 4.900-7.933) were promoting factors for residents' salt reduction practice.
Conclusions:Residents in Xicheng District demonstrated high awareness and supportive attitudes regarding salt reduction, yet the actual practice rate was relatively low. Factors influencing salt reduction practice included gender, age, chronic disease, salt reduction knowledge and attitude.
