Knowledge of modifiable risk factors of Coronary Atherosclerotic Heart Disease (CASHD) among a sample in India

Background

The prevalence of Coronary Atherosclerotic Heart Disease (CASHD) is increasing in India. Several modifiable risk factors contribute directly to this disease burden. Public knowledge of such risk factors among the urban Indian population is largely unknown. This investigation attempts to quantify knowledge of modifiable risk factors of CASHD as sampled among an Indian population at a large metropolitan hospital.

Methods

A hospital-based, cross sectional study was conducted at All India Institute of Medical Sciences (AIIMS), a major tertiary care hospital in New Delhi, India. Participants (n = 217) recruited from patient waiting areas in the emergency room were provided with standardized questionnaires to assess their knowledge of modifiable risk factors of CASHD. The risk factors specifically included smoking, hypertension, elevated cholesterol levels, diabetes mellitus and obesity. Identifying 3 or less risk factors was regarded as a poor knowledge level, whereas identifying 4 or more risk factors was regarded as a good knowledge level. A multiple logistic regression model was used to isolate independent demographic markers predictive of a participant's level of knowledge.

Results

41% of the sample surveyed had a good level of knowledge. 68%, 72%, 73% and 57% of the population identified smoking, obesity, hypertension, and high cholesterol correctly, respectively. 30% identified diabetes mellitus as a modifiable risk factor of CASHD. In multiple logistic regression analysis independent demographic predictors of a good knowledge level with a statistically significant (p < 0.05) adjusted odds ratio (aOR) were: routine exercise of moderate intensity, aOR 8.41 (compared to infrequent or no exercise), no history of smoking, aOR 8.25, and former smokers, aOR 48.28 (compared to current smokers). Although statistically insignificant, a trend towards a good knowledge level was associated with higher levels of education.

Conclusion

An Indian population in a hospital setting shows a lack of knowledge pertaining to modifiable risk factors of CASHD. By isolating demographic predictors of poor knowledge, such as current smokers and persons who do not exercise regularly, educational interventions can be effectively targeted and implemented as primary and secondary prevention strategies to reduce the burden of CASHD in India.

The From The Heart study: a global survey of patient understanding of cholesterol management and cardiovascular risk, and physician-patient communication

OBJECTIVES

Cardiovascular disease (CVD) is the leading cause of mortality worldwide. A high level of low-density lipoprotein cholesterol (LDL-C) is a major CVD risk factor. Guidelines recommend effective cholesterol management and set LDL-C goals, yet deficiencies exist in physician implementation of these recommendations and in patient uptake of the advice. However, little is known of patient perceptions about CVD risk.

METHODS

Patients and physicians were randomly selected from ten countries to complete a confidential, semi-structured questionnaire.

RESULTS

Response rates were 27% (n = 750) for physicians and 83% (n = 1547) for patients. Patients believed cancer (43%) to be a greater cause of mortality than heart attack or stroke (34%). Despite 77% of patients claiming to be satisfied with information on high cholesterol, only 26% were aware that heart attack was a possible consequence, and only 35% of patients thought they had achieved their cholesterol goals. Virtually all physicians (99%) claimed to inform patients of their cholesterol level, while 18% of patients reported that they were not informed. Although patients and physicians were selected at random, limitations of this survey relate typically to the reliability of physician and patient responses and the possibility that the survey population may not represent the overall population. A broad range of patients' backgrounds and a high response rate (83%) suggest these effects would be minimal in the patient population.

CONCLUSIONS

The From The Heart study has shown surprisingly poor knowledge of CVD risk amongst patients with elevated cholesterol. This may contribute to poor concordance with recommendations and treatment.

Knowledge of healthy diets among adolescents in eastern Saudi Arabia

BACKGROUND

Bad dietary habits, such as eating high-fat/high-energy food, can contribute to obesity in adolescents, which tends to persist into adulthood. The objective of this study was to determine the level and sources of knowledge about foods and healthy diets among male and female adolescents.

METHODS

This was a cross-sectional study of a sample of male (n=1240) and female (n=1331) adolescents from third grade, intermediate and all three grades of secondary school students in the Al-Khobar Area, eastern province of Saudi Arabia. A self-administered questionnaire was used to collect information.

RESULTS

Approximately 51% of the male and 65% of the female students recognized unsaturated fats as healthy foods. However, 10% of the males and 8% of females reported saturated fats as healthy food items. About 49% of the males and 66% of the females correctly defined cholesterol. Dietary knowledge of both male and female students on the dangers of unhealthy foods and the benefits of fiber-rich diets was found to be unsatisfactory. The main sources of knowledge about health and disease reported by the male and female respondents were television (58% and 61%, respectively), magazines (31% and 39%) and daily newspaper (33% and 34%). Primary health care centers (PHCCs) staff were the least source of knowledge (17% and 16%).

CONCLUSIONS

Knowledge of healthy diets among school students was inadequate. It is recommended that health education and information about healthy eating habits and lifestyle be included in school curricula.
