Effect of a Training Programme on Knowledge and Practice of Lifestyle Modification Among Hypertensive Patients Attending Out-patient Clinics in Lagos
Hypertension is the most common non-communicable disease and the leading cause of cardiovascular disease in the world.Many people with hypertension are unaware of their condition making treatment infrequent and inadequate. According to Seven Joint National Committee Criteria (JNC7), the precise rule for the treatment of hypertension begins with lifestyle modifications and ends with medication. Unfortunately, many patients diagnosed to be hypertensive don’t usually have proper education about lifestyle modification. Lifestyle modification is advised for all patients with hypertension, in respective of pharmacological treatment, because it may reduce or even abolish the need for medications.
The objective of the study was to determine the effect of a training programme on knowledge about hypertension, lifestyle modification and practice .Quasi experimental method was used for this study to determine the effect of a training programme on knowledge and practice of lifestyle modification. Sample size of 60 participants diagnosed to be hypertensive and registered at the general out-patients and medical out-patients clinics were used. (Control group n=30, intervention group n=30). Two research settings were selected randomly from the three tertiary hospitals in Lagos state. One of the hospitals was randomly selected to be the control group and the other the experimental group. Purposive sampling was used to select the participant from each setting. Data were collected through administered questionnaire using a modified structured questionnaire from World health organization for hypertensive patients and hypertension knowledge-level scale (HK-LS). Data obtained were coded and analysed using SPSS version 21.0 statistical software. Variables and research questions were analysed using descriptive analysis e.g. percentage, mean, and standard deviation and to show relationship between dependent and independent variables. Hypotheses were tested using inferential t-test at 0.05 level of significance.
Demographic data showed that female were more prevalent in the study, level of literacy was fair in both groups. Above ninety three percent were Yoruba in the control group and above 44% in the experimental group. This is because this study was carried out in South-west Nigeria which is mainly dominated by the Yoruba. Results suggested that pre-test general knowledge of hypertension was low in both groups (t=2.836, p=0.065). Knowledge about lifestyle modification was also low in both groups (t=0.256, p=0.7989). Practice of lifestyle modification as reported by the participant was also inadequate (t=1.390, 0.1705). Intervention was given and there was significant increase in the level of knowledge about hypertension and lifestyle modification (t=2.665, p=0.010) and (t=4.741, p=0.001) and improvement on their practice ((t=5.599, p=0.001)) after intervention.
The study concluded that, there is relationship between knowledge and practice, hence, it is pertinent that health care providers especially the nurses should help provide continuous and focused health education and training for the hypertensive in order to improve their knowledge and practice of lifestyle modification therefore controlling their blood pressure and reducing the risk for cardiovascular diseases. It is therefore recommended that health sector should intensify efforts on health educating the populace on the type of lifestyle that put them at risk of developing hypertension.
