[Implementation and evaluation of a childhood dental health program in a community: twenty-year observational data].

UNLABELLED: PURPOSE To evaluate a long-term community-based childhood dental health program comprising of caries screenings of one- and two-year old kindergarten and pre-school children as well as in groups aged 1.5- and 3-years. METHODS: Fluoride treatment was introduced to 1.5-year, 2-year, 3-year screening from 1995, 1-year screening from 1997, and kindergarten/pre-school children from 2002 in Kyowa town, Makabe, Ibaraki (Kyowa district of Chikusei city) . Tests for caries prediction and caries bacteria load were also introduced from 1990 and 1995, respectively. To evaluate improvement in the dental health program between 1984 and 2004, we compared the prevalence trend for dental caries in Kyowa town with that in 7 other adjacent communities within the same public health center area, the Ibaraki prefectural average and data for all Japan. RESULTS: Between 1984 and 2004, the prevalence of dental caries declined by 59% for 3-year children with a large decrease from 1995, and by 57% for 1.5-year children. Decline during the twenty years ranked first and second among the communities, respectively, and was also larger than the prefectural and national averages. For 3-year children, the reduced prevalence of dental caries may have been enhanced by the introduction of fluoride treatment in 1995. CONCLUSION: A community-based dental health program including fluoride treatment for 1- and 2-year old kindergarten/pre-school children as well as for those aged 3- and 1.5 years may have had a larger impact on reducing dental caries in Kyowa town than in other communities, Ibaraki prefecture and all Japan.

[Individualized health education with sports gym use and dietary advice for overweight and obese persons in a community. Kokuho Health-up model Program in Chikusei-shi (former Kyowa town)].

OBJECTIVE: We aimed to evaluate the effect of a community-based health educational program for overweight or obesity persons, as the Kokuho Health-up model Program in Kyowa area of Chikusei-shi. METHODS: The subjects were men and women aged 35 to 60 years who participated in annual health check-ups from 1998 to 2003 and were living in Chikusei-shi (Former Kyowa town) Ibaraki prefecture, had a body mass index > or = 25.0 kg/m2 at baseline, and agreed to a 6-month intervention. The participants were divided into 59 persons for the intense intervention group (health checkups, dietary advice, monthly individual health education, and exercise in sports facilities three times/ week), 62 persons for the moderate intervention group (health checkups, dietary advice, monthly individual health education, and exercise in sports facilities or at home once/week), and 34 persons for the control group (only health checkups). Criteria for the metabolic syndrome were those published by the Japanese 8 committee. RESULT: During the 6-month intervention, the follow-up rate was 86%. At the baseline, there were no differences in physical status or lifestyles among the intervention and control groups. The frequency of use of sports facilities was 6.4 times/month for the intense intervention group and 1.9 times/month for the moderate intervention group. Mean body weight did not change in the control group (70.6 kg to 70.9 kg, P = 0.84) but decreased in the intense intervention group (71.4 kg to 69.5 kg, P < 0.001) and moderate intervention group (69.5 kg to 66.7 kg, P < 0.001). Mean abdominal circumference increased in the control group (91.0 cm to 93.9 cm, P = 0.001) but did not change in intense intervention group (90.1 cm to 90.0 cm, P = 0.29) or moderate intervention group (90.4 cm to 88.7 cm, P = 0.39). The prevalence of metabolic syndrome increased in the control group (18.2% to 40.0%, P = 0.01) but did not change in either of the intervention groups. CONCLUSIONS: We found a significant reduction of body weight and an attenuation of the increase of metabolic syndrome in both intensive and moderate intervention groups. The present community-based educational program may be effective for health promotion with overweight or obese middle-aged adults.

[Evaluation of a community-based health education program for salt reduction through media campaigns].

PURPOSE: To provide the strategies, achievement and evaluation of a community health education program for salt reduction with media campaigns. METHODS: The intervention community was Kyowa town (A district of Chikusei city, census population in 1985 = 16,792) where we have systematically conducted a community-based blood pressure control program since 1981, and health education on reduction of salt intake since 1983 for primary prevention of hypertension. The education program was performed through media campaigns including use of banners, signboards, posters, and calendars with health catchphrases. We also used catchphrase-labeled envelopes when sending documents from the municipal health center to individuals. Health festivals were held annually to enhance health consciousnesses and to improve health behavior. Some of the posters and calligraphy were painted or drawn by elementary schoolchildren as part of their education. The program was evaluated by repeated questionnaires and examination of salt concentrations of miso soup and dietary salt intake. RESULTS: Between 1983 and 1988, the prevalence of persons who were aware that health consultation including blood pressure measurements were available at the town office increased from 65% to 84%. The prevalence of those who knew the salt intake goal (10 g or less/day) increased from 47% to 63% and that of those who reported to reduce salt intake also increased from 38% to 58%. As for salt concentrations of miso soup, the proportion with less than 1.1% increased from 47% to 66% between 1985 and 2004. Age-adjusted mean salt intake for persons aged 40-69 years declined from 14 g to 11 g in men and from 12 g to 10 g in women between 1982-1986 and 2000-2004. CONCLUSION: A long-term systemic education program through media campaigns proved feasible with the cooperation of community leaders, schools and food associations.
