健康日本21（第二次）に関する国民の健康意識・認知度とその推移に関する調査研究

Abstract

Objectives To examine the prevalence of health consciousness regarding "Health Japan 21" (2nd edition) among the Japanese population, we conducted a telephone survey of a sample extracted randomly from the whole nation in 2013 and 2014.Methods We extracted 1800 men and women with 150 persons for each gender and 10-year age group (6 age groups ranging from 20 years to 70 years and older) using Random Digital Dialing sampling. Each participant was asked about 1) recognition of the following items: "Health Japan 21," "healthy life expectancy," "metabolic syndrome (MetS)," "chronic obstructive pulmonary disease (COPD)," "locomotive syndrome," "Active Guide," "WHO Framework Convention on Tobacco Control," and "Smart Life Project" and 2) health consciousness toward the following: "health examination taken within the past one year," "smoking status," and "the amount of vegetables considered desirable to consume per day for health." We performed simple tabulation of the collected answers and cross-tabulation by sex and age groups, respectively. For each question about recognition, we categorized "I know the name and meaning" and "I know the name but not the meaning" as "awareness." We compared data between 2013 and 2014, sexes, and age groups, using chi-squared test.Results In 2013, the top 5 items with high awareness were "MetS" (96.2%), "COPD" (51.1%), "healthy life expectancy" (34.2%), "locomotive syndrome" (30.2%), and "WHO Framework Convention on Tobacco Control" (28.0%). Moreover, awareness of "healthy life expectancy," "locomotive syndrome," and "Active Guide" were significantly higher in 2014 than in 2013. Meanwhile, the proportion of participants who correctly chose "350 grams" as "the desirable amount of vegetables to consume per day" was 41.6% in 2013 and became significantly higher at 50.1% in 2014. In 2013, awareness of "healthy life expectancy," "COPD," and "locomotive syndrome" and the proportion of correct answers for "the desirable amount of vegetables to consume per day" were significantly higher among women than among men. In 2013, there were significant differences among age groups in awareness of "MetS," "COPD," "healthy life expectancy," and "locomotive syndrome" and the proportion of correct answers for "the desirable amount of vegetables to consume per day."Conclusion Awareness of "healthy life expectancy," "locomotive syndrome," and health consciousness of "the desirable amount of vegetables to consume per day" were significantly higher in 2014 than in 2013. There were discrepancies on respective items among both sexes and age groups. Therefore, interventions for groups with lower awareness or health consciousness may be required.
