A sample of 398 35-44-yr-old and 559 65-74-yr-old Hong Kong Chinese were interviewed by trained interviewers using a structured questionnaire in an oral health survey conducted in 1991. The present analysis aimed to describe the dental-care-seeking behaviour and attitudes of these subjects. It was found that 43% of the younger and 23% of the older age group had visited a dentist within the past year. More than half of the elderly and a quarter of the adults had not been to a dentist for 3 yr or more, and the main reason given by these subjects was that they felt that nothing was wrong. The vast majority of the subjects consulted a dentist only when they had toothache or other dental problems. Less than 20% of the 35-44-yr-olds visited a dentist for a check-up or teeth cleaning, and these subjects were described as having a prevention-oriented attitude toward oral care. The result of a logistic regression analysis showed that there was a higher chance for subjects to have this attitude if they had dental programme coverage, perceived their teeth to be good, had better dental health knowledge, had a more positive dental attitude, and were less anxious about dental care. However, the influence of these factors was quite weak, because the overall percentage of correct classification of the model was 83.7% and the sensitivity was only 23.3%. [ABSTRACT FROM AUTHOR]

The purpose of this paper was to study possible relationships between traditional Chinese health beliefs and health practices in adult Chinese in a modernized society. The study populations comprised 398 35-44-yr-old and 559 65-74-yr-old Hong Kong Chinese. The respondents were categorized into three groups with weak, moderate, or strong Chinese beliefs on the basis of interview questions on the causes of gum disease. Chinese preventive practices and Chinese pain practices were defined according to respondents' reported use of recommended traditional cures. Questions on generally accepted oral practices were phrased in terms of frequency of daily brushing of teeth, use of toothpicks the previous day, and whether or not teeth were flossed the previous day. Around one-third of the respondents had weak, almost one-half had moderate, and around one-quarter expressed strong Chinese health beliefs. No significant differences in Chinese health beliefs were found between men and women in either age group, or between the age groups. In the 35-44 age group, more of those with a higher education were in the "weak" Chinese health belief category, whereas, conversely, more of those with a lower education expressed stronger Chinese health beliefs (P<0.05). Women in both age groups reported significantly more frequent brushing. Toothpicks were used by around three-quarters of both age groups, but flossing was extremely rare. Chinese preventive practices were reported significantly more frequently by those in the older group who held strong Chinese health beliefs than those with moderate or weak beliefs, whereas the trend in the younger group was not significant. Chinese pain practices were reported very infrequently. Chinese health beliefs did not correlate with use variables. In the older group, Chinese health beliefs correlated strongly with preventive practices and with knowledge. [ABSTRACT FROM AUTHOR]

The purpose of this study was to describe the state of the dentition of middle-aged and elderly Chinese in Hong Kong in terms of teeth present, tooth spaces, and prosthetic treatment received. In an oral health survey conducted in 1991 in Hong Kong, a sample of 372 35-44-yr-olds and 537 noninstitutionalized 65 74-yr-olds was interviewed and clinically examined. In all dentate subjects, each tooth was scored for the presence/absence of that tooth, a tooth space of 5.5 mm which had not been treated, or the presence of a denture or pontic replacing that tooth. Each denture was assessed according to a set of criteria. None of the 35 44-yr-olds were edentulous and the mean number of teeth present was 27.5. About 40% of the third molars and about 35% of the mandibular first molars were missing. For only 1% of the missing teeth had space closure resulted in missing teeth not being recorded as tooth spaces or treated tooth spaces. Overall, 72% of the 35-44-yr-olds had no prosthesis, 17% had a bridge or bridges, 12% had a denture or dentures, and 1% had both. Of the 65-74-yr-olds, 12% were edentulous, and the dentate subjects had a mean number of 17 teeth present. About 70% of the molars were missing. Overall, only 29% of the elderly had no prosthesis, 52% had a denture or dentures, 33% had a bridge or bridges, and 13% had both. Only 35% and 28%, respectively, of the middle-aged and elderly denture wearers had no complaint about their dentures. There were more assessed problems in the dentures of the elderly than in those of the younger adults, over one-third of the partial dentures and half of the mandibular complete dentures being unstable and unretentive.

The objectives of this analysis were to describe the dental service use pattern of the 35-44- and 65-74-yr-old age groups and to determine to what extent this pattern could be explained by selected sociodemographic and attitudinal variables. The study populations comprised 398 35-44-yr-old and 559 65-74-yr-old Hong Kong Chinese. Use of dental services was determined on the basis of the respondents' own perception of the regularity of their dental visits and by the time since the last dental visit. The younger groups was categorized into regular users, irregular users, and nonusers, and the older group was categorized into three groups according to last dental visit (within 2 yr, 2-5-yr, 5 yr or more). A modification of the Andersen and Newman model for individual determinants of health care use was used as the framework for a logistic regression analysis. Predisposing variables were sex, education, occupation, attitudes, knowledge, preventive orientation, and dental anxiety; enabling variables were Family Possession Index, income, family support and access to a dental programme; need variables were perceived conditions of teeth, dental problems, dental pain, need for treatment, normative need for treatment, and denture wearing. In general, use of dental services was low. For the 35-44-yr-olds, the best regression model (sensitivity: 62%, specificity: 95%, overall correct classification: 88%) indicated that there was an increased probability of having a regular dental care pattern if respondents were prevention oriented, had access to a dental benefit programme, had not experienced pain, had a higher income, perceived their teeth as fair or poor, and perceived a need of treatment. For the 65-74-yr-olds, three variables remained in the final model (sensitivity: 51%, specificity: 68%, overall correct classification: 61%). [ABSTRACT FROM AUTHOR]
