Background Health beliefs are relevant to consider in patients with type 2 diabetes since disease control depends mainly on the patient’s behaviour. The aim of this study was to assess the association between health beliefs and glycated hemoglobin levels in Mexican patients with type 2 diabetes. Methods An analytical cross-sectional study was conducted, and 336 patients were included. Fasting blood levels of glycated hemoglobin, glucose, cholesterol; triglycerides, high-density lipoprotein cholesterol (HDL-c), and low-density lipoprotein cholesterol (LDL-c) were measured. Body fat percentage, weight, height; waist circumference, and systolic and diastolic blood pressures were also obtained. A previously validated self-administered questionnaire was used to assess the health beliefs with regards to non-pharmacological treatment. Health beliefs were classified as positive, neutral, and negative. Results The average age of patients was 54.7 ± 8.5 years, with a higher proportion of females (69%). The questionnaire had a good internal consistency with a Cronbach’s alpha score of 0.83. More than 90% of patients attributed a health benefit to diet and exercise, 30 to 40% experienced barriers, and more than 80% had a perception of complications associated to uncontrolled diabetes. Patients with positive health beliefs had lower HbA1c levels (8.2 ± 1.7%) compared to those with neutral (9.0 ± 2.3%), or negative (8.8 ± 1.8%; p = 0.042). The LDL-c levels were lower (p = 0.03), and HDL-c levels were higher (0.002) in patients with positive heath beliefs. Conclusions Positive health beliefs are associated with better metabolic control indicators in patients with type 2 diabetes.

Aim: To assess the effects of a multimedia diabetes education intervention and nutritional therapy on lifestyle changes and metabolic control of patients with type 2 diabetes mellitus. Material and Methods:We studied 219 patients with type 2 diabetes mellitus aged 56 ± 8 years (28% males). They received education through a multimedia site about control indicators, complications, nutrition and physical exercise, among others. They also received a personalized nutritional therapy. They were followed-up for one year. At baseline and the end of follow up they were weighed, and their waist circumference and blood pressure were measured. A fasting blood sample was withdrawn to measure glucose, glycosylated hemoglobin and lipid profile. Lifestyles were assessed using a self-administered questionnaire called IMEVID. Results: The median duration of diabetes was six years. During the follow up, patients had a significant reduction in body weight, waist circumference and blood pressure and improvements in glycosylated hemoglobin, HDL and LDL cholesterol. Seven and 13% of patients reported favorable lifestyles at baseline and the end of follow up, respectively (p < 0.01). Compared with their counterparts with unfavorable lifestyles, patients with a favorable lifestyle had a significantly lower weight and glycosylated hemoglobin at the end of follow up. Conclusions: The educational intervention along with nutritional therapy improved metabolic control and lifestyles in this group of diabetic patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
