Development of hypertension in obese subjects seen in general practice
Insights
Overweight individuals have a 3-4 times higher risk of hypertension compared to normal-weight individuals. Abdominal fat distribution is particularly linked to hypertension prevalence in those under 50.
Area of Science:
- Cardiology
- Public Health
- General Practice
Background:
- Hypertension is a significant public health concern.
- Obesity is a known risk factor for hypertension.
- Understanding the relationship between overweight, fat distribution, and hypertension is crucial for prevention and early detection.
Purpose of the Study:
- To investigate the association between overweight and hypertension.
- To explore the role of fat distribution in hypertension prevalence.
- To assess the risk of hypertension in overweight individuals compared to normal-weight individuals.
Main Methods:
- Analysis of continuous morbidity registration data from four general practices.
- Comparison of overweight individuals (317 men, 565 women) with age-matched normal-weight controls (444 men, 627 women).
- Follow-up period of up to 17 years, including analysis of fat distribution in 292 overweight subjects.
Main Results:
- Overweight individuals exhibited a 3-4 times higher risk of hypertension compared to normal-weight individuals.
- A linear relationship was observed between the degree of overweight and hypertension incidence in women.
- Abdominal fat deposition was associated with hypertension prevalence, especially in individuals under 50 years of age.
Conclusions:
- Overweight status and abdominal fat distribution are significant risk factors for hypertension.
- Fat distribution, alongside the degree of overweight, can aid in the early detection of hypertension.
- Prevention of overweight is essential in general practice due to challenges in long-term treatment success.
Abstract:
A group of 317 overweight men and 565 overweight women was compared with an age-matched normal control group of 444 men and 627 women in order to establish whether hypertension was more often recorded in the obese group. This was done by analysing the continuous morbidity registration of four general practices with a follow-up of up to 17 years. The risk of hypertension was found to be three to four times higher in overweight persons than in those of normal weight, and in women a linear relationship was found between the degree of overweight and the incidence of hypertension. The fat distribution was studied in 292 overweight persons, and fat deposited predominantly in the abdominal region was found to be related to the prevalence of hypertension, particularly in subjects under 50 years of age. Along with the degree of overweight, therefore, the fat distribution might be a useful aid in the early detection of hypertension. Since it is difficult to achieve long-term success in the treatment of overweight, its prevention merits special attention in general practice.
