Abstract

Purpose: The health risk of women increases after menopause. This study evaluated the effectiveness of a public health center-based nutrition education program for hypertension in women older than 50 years of age. Methods: The program included 8-week nutrition education and 8-week follow-up with keeping a health diary and nutrition counseling. The program was evaluated three times: before and after the nutrition education, and after the follow-up. The subjects were classified into hypertensives (n = 44) or normotensives (n = 71). Results: The rate of taking antihypertensive drugs in the hypertensive group was 86.4%. The systolic blood pressure decreased in the hypertensive and normotensive groups after nutrition education (p < 0.05). The body weight (p < 0.001), BMI (p < 0.001), waist circumference (p < 0.001), and percent body fat (p < 0.01) were also decreased after nutrition education in both groups. The hypertensive group showed an increase in HDL-cholesterol level (p < 0.001) and decreases in triglycerides (p < 0.01) and LDL-cholesterol (p < 0.05) levels after completion of the program. The normotensive group also displayed significant changes in HDL-cholesterol (p < 0.001) and triglycerides (p < 0.01). The dietary habits and nutrition knowledge on sodium and hypertension were improved in both groups (p < 0.001). The total score of dietary behavior related to the sodium intake was improved in the normotensive group (p < 0.001). The total score of the high sodium dish frequency questionnaire decreased in both groups after nutrition education and completion of the program compared to that before the program. Decreases in the consumption frequencies of noodles, pot stews and stews, Kimchi, and beverages were significant. The total self-efficacy score was increased in both groups by the program (p < 0.001). In particular, the hypertensive group showed improvement in all items. Conclusion: This public health center-based nutrition education program may contribute to the prevention and management of hypertension and chronic diseases in women over 50 years of age.

본 연구는 선행연구로 개발된 고혈압 관리를 위한 식생활 영양교육 프로그램의 효과를 평가하고자 서울의 3개 지역 보건소에서 50세 이상의 여성을 대상으로 영양교육 8주와 추후관리 8주로 구성된 16주간의 교육을 실시하고 정상혈압군 (71명)과 정상혈압을 초과한 고혈압군 (44명)으로 나누어 분석하였다. 교육시작 전, 8주 교육 후, 프로그램이 종료된 16주 후에 실시한 혈압 측정 및 신체계측, 혈액분석, 설문조사를 분석한 결과는 다음과 같다. 고혈압군의 혈압강하제 복용 비율은 86.4%였고 체중, BMI, 체지방비율, 허리둘레가 정상혈압군에 비해 높았다. 영양교육 8주 후 고혈압군과 정상혈압군의 수축기혈압이 감소되었고 (p < 0.05), 체중 (p < 0.001), BMI (p < 0.001), 허리둘레 (p < 0.001), 체지방비율 (p < 0.01)이 감소하였다. 혈액검사결과 고혈압군은 프로그램이 종료된 16주 후 HDL-콜레스테롤 증가 (p < 0.001)와 중성지방 감소 (p < 0.01), LDL-콜레스테롤 감소 (p < 0.05)가 나타났고, 정상혈압군도 HDL-콜레스테롤 (p < 0.001)과 중성지방 (p < 0.01)의 유의미한 변화가 나타났다. 일반식습관 총점수와 규칙적인 식습관, 균형 잡힌 식습관, 건강을 의식한 식습관의 항목 소계, 나트륨 관련 영양지식 총점이 두 군 모두 교육 후 유의적인 상승을 나타냈다 (p < 0.001). 또한 정상혈압군의 나트륨 관련 식행동 총점이 상승되었고 (p < 0.001) 고혈압군에서도 향상되는 경향을 나타냈다. 이와 부합하여 고나트륨 함유음식의 섭취빈도 총점이 교육 후 유의적으로 감소하였고 두 집단 모두 국수류, 찌개와 탕류, 김치류와 음료류의 섭취빈도가 낮아졌다. 혈압관리를 위한 자기효능감점수의 총점이 고혈압군과 정상혈압군 모두 유의적으로 상승하였는데 (p < 0.001) 특히 고혈압군은 자아효능감의 모든 문항점수가 향상되었다. 종합하면 50대 이상 여성을 대상으로 실시한 본 식생활영양교육은 혈압이 높은 군과 정상혈압군 모두에서 혈압관리 뿐만 아니라 신체계측지표 및 혈액지표에 긍정적인 변화를 유도하고 저나트륨 관련 식행동을 비롯한 일반식습관의 전반적 개선효과를 보였다. 이는 건강위험에 대한 각성, 식생활 변화를 유도할 수 있는 계기와 모니터링을 통한 실천 관리를 제공한 프로그램이 대상자의 요구에 부합한 결과로 생각된다. 본 연구는 건강위험이 높아지는 50대 이상 여성의 혈압관리 및 만성질환 예방과 식생활 관리를 위해 보건소에 기반한 지역사회 교육 프로그램의 유효한 모델을 제시한 점에 의의가 있다.
