1108Effectiveness of nursing counseling for patients with cardiovascular risk factors: controlled clinical trial with a 24 months post-intervention follow-up
Abstract Objective To establish the effect after 24 months of a face-to-face and telephone nursing counseling intervention, aimed at controlling cardiovascular risk factors (hypertension, dyslipidemia and overweight) and improving health-related quality of life (HRQoL) in patients of the cardiovascular health program of family health centers of Concepciόn, Chile. Methods Randomized controlled clinical trial with a 24 months post-intervention follow-up. 120 patients with cardiovascular risk factors under the cardiovascular health program were recruited from 6 family health centers and randomized into a control group (60) and an intervention group (60). The intervention group received the regular care in addition to face-to-face and telephone nursing counseling. Baseline measurements were taken and also at the end of the intervention (7 months). Participants returned then after 12 and 24 months for follow-up evaluations. A total of 109 subjects completed the intervention at 7 months and 45 returned at 24 months. During follow-up evaluations both groups continued to receive regular care given in the health centers. The measurements consisted of HRQoL (physical and mental health), systolic blood pressure (SBP) and diastolic blood pressure (DBP), body mass index (BMI), abdominal circumference (AC), total cholesterol (TC), low density lipoproteins (LDL-Chol), high density lipoprotein (HDL-Chol), atherogenicity index (LDL/HDL), cardiovascular risk factor (TC/HDL), 10-year coronary risk. Ethical requirements were considered and statistical analysis was carried out using MANCOVA and d-Cohen repeated measurements. Results The analysis of the effects of the intervention in the 24-month follow-up showed that subjects in the intervention group only maintained significant improvement of AC over time (F=3.18; p=0.03), compared to the control group. Conclusion Although participants in the intervention group only maintained the AC improvement over time, this can be regarded as an indirect indicator of the presence of intra-abdominal fat that makes it possible to predict and classify the risk of cardiovascular disease. Long-term follow-up studies are required to investigate behaviors and mechanisms that contribute to maintaining improvements in this indicator. Additionally, future research should include reinforcement activities, either face-to-face or by telephone, to help maintain the positive results of interventions.
