title: Opportunistic Screening for Hypertension and Selected Cardiovascular Risk Factors among Adults Attending a Primary Health Center in Puducherry, India.
abstract: BACKGROUND
  India is currently suffering from an epidemic of noncommunicable diseases; it is thus imperative to screen for cardiovascular risk factors in people visiting Primary Health Centers (PHCs). The objective of the study was to measure the amount of undiagnosed hypertension and selected cardiovascular risk factors present among the adult population through opportunistic screening at the PHC.
  
  
  METHODS
  A facility-based opportunistic screening program was carried out in a PHC in rural Puducherry. Patients and accompanying persons aged 30 years and above, who attended the daily outpatient department (OPD) were included. The OPD provides outpatient services and medical procedures or tests without requirement of an overnight stay, and functions for 4 h a day. Known hypertensive patients and pregnant women were excluded. Information on age, gender, diabetes status, and personal history of tobacco and alcohol use were collected using an interview schedule. Height, weight and waist circumference were measured, along with blood pressure and blood sugar using standard protocols. Systolic blood pressure (SBP) ≥140 and/or diastolic blood pressure (DBP) ≥90 mm Hg was taken as hypertension. SBP of 120-139 mm Hg and/or DBP of 80-89 mm Hg were taken as prehypertension.
  
  
  RESULTS
  A total of 324 participants were screened; 56.8% were females. The mean standard deviation (SD) age of the participants was 47.7 (SD 12.6) years. Hypertension and prehypertension were present in 17.9% and 37.7% of the participants respectively. 17.3% participants had diabetes. 22.2% and 21.3% of all participants were current users of tobacco and alcohol respectively. Generalized obesity was present in 31.8% of the participants; 19.1% were overweight. 45.1% participants had central obesity.
  
  
  CONCLUSIONS
  A relatively large proportion of adults were found to have prehypertension and obesity, thus showing the need for early intervention.
