Non-communicable disease (NCD) epidemics are emerging or accelerating in most developed countries, and cardiovascular diseases (CVD), cancers, diabetes and chronic obstructive pulmonary diseases are becoming major contributors to the burden of disease. [1] India too illustrates the phenomenon of 'health transition', which positions NCDs as a major public health challenge of growing magnitude in the 21 st century. In 1990, India accounted for 19% of all deaths, 16% of all NCD deaths and 17% of all CVD deaths in the world. In India alone CVDs accounted for around 2.4 million deaths, in contrast to nearly 3.2 million deaths in all industrialized countries put together. [1] In recent times, life expectancy has increased with several undesirable alterations in lifestyle. Hence, there is an increase in both the dose and duration of risk factors, leading to an increase in lifestyle diseases and their consequences.

The incidence of CVDs is greater in urban areas than in rural areas, reflecting the acquisition of several risk factors such as tobacco consumption, lack of physical activity, unhealthy diet and obesity. Usually skilled workers estimate the prevalence of CVDs after surveys. However, there is less evidence available regarding the use of alternative methods of estimating prevalence. Keeping these things in mind, a study was carried out in a selected community of Chandigarh to find out the prevalence of self-reported cardiovascular diseases.

   Materials and Methods Top

A cross-sectional survey was carried out in ≥40-year age group, in a purposively selected urban sector of Chandigarh. The study was conducted during January to April 2005. Nine hundred subjects selected purposively were considered for the study. The first house for the survey was selected randomly, and thereafter houses to the left were taken continuously. A health worker who was trained in WHO CVD risk assessment and management package [2] sought information regarding physician-diagnosed cardiovascular diseases. Diseases included in the survey were hypertension, diabetes and heart disease (angina, heart attack). The prescriptions of the doctors and intake of medicines for these problems were verified with the subjects. The self-reported prevalence was compared with organized studies done on similar problems in the area.

   Results Top

A total of 541 families were surveyed, and a total of 969 eligible populations were identified. Almost half (50.7%) the study subjects were males and 49.3% were females. Approximately half (45.4%) belonged to the age group of 40-50 years.

The prevalence of physician-diagnosed self-reported hypertension was found to be 32.3% in the study population with prevalence being 31.7% and 32.9% in males and females, respectively. The prevalence of self-reported hypertension was found to be more (64%) in the age group of >70 years.

As mentioned before, angina and heart attack were considered heart diseases. The prevalence of self-reported heart disease was found to be 10.8% (male: 11.2%, female: 10.5%). The overall prevalence of self-reported diabetes was found to be 13.4% with prevalence in males and females being 15.2 and 11.5%, respectively. It was observed that 11.6% cases had co-morbid conditions. The prevalence of physician-diagnosed CVDs is given in [Table - 1].

   Discussion Top

The prevalence of hypertension has almost doubled over 30 years in Chandigarh. The prevalence of hypertension in 1968 was 26.9%, and it has increased to 44.9% in 1996-97 among males of >30 years of age. [3] Unfavourable changes including prevalence of hypertension, physical inactivity and body fat make Chandigarh population highly vulnerable to cardiovascular morbidity and mortality. Our study shows the prevalence of self-reported hypertension to be 32.3%. Another study among the elderly (>65 years) in Chandigarh in 2002 showed the prevalence to be 58%. [4] In our study, the prevalence of self-reported hypertension was found to be 64% in the age group of >70 years.

Another study conducted in Chandigarh showed the prevalence of angina as ascertained by questionnaire to be 6.3% in both males and females in the age group of >55 years. [5] Similarly, the prevalence of physician-diagnosed heart attack was found to be 7.5 and 3.1% in males and females, respectively. [5] In our study, the prevalence of self-reported heart disease was 10.8% (11.2% and 10.8% in males and females, respectively). In the same study, the prevalence of physician-diagnosed diabetes was found to be 13.8 and 13.2% in males and females, respectively. In our study, the overall prevalence of self-reported diabetes was found to be 13.4%, with prevalence in males and females being 15.2 and 11.5%, respectively. The results of both these studies were comparable.

The study is different from other studies because of its methodology. The prevalence pattern found out by this method showed comparable results with that of surveys conducted in this area by skilled workers. The findings of the study are important for developing countries due to the shortage of skilled manpower for undertaking organized surveys. This methodology could be used in literate urban population to find out the magnitude of CVDs.
