Socioeconomics, health-related factors, and tooth loss among the population aged over 80 years in China

Abstract

Background The prevalence of tooth loss varies across the globe among oldest-old individuals. The presence of fewer than 20 teeth in old age was associated with a decrease in people’s health and quality of life. This paper explored the association between socioeconomics, health-related factors, and tooth loss among the population over the age of 80 in China. Methods The tooth loss status of older Chinese adults was collected with a structured questionnaire from the 8th wave of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). A total of 6716 individuals aged 80 years and above were included. Logistic regression was used to assess the association between socioeconomic statuses, dietary intake at approximately 60 years old, health-related factors, and tooth loss. Results Of the 6716 individuals aged 80 years and above, the composition of the group with fewer teeth for both men and women was statistically significant in many ways. Multivariate logistic regression analyses show that for men, being older than 90 years and being ADL disabled (adjusted OR: 1.71, 95% CI: 1.01–2.89) are factors that are significantly and consistently associated with a higher risk of having fewer than 20 teeth, while having a higher household income per capita (adjusted OR: 0.56, 95% CI: 0.32–0.99) decreases the risk. For women, an age of above 95 years, brushing teeth less than once per day (adjusted OR: 1.96, 95% CI: 1.26–3.03), consuming sugar some of the time as opposed to less than once per month at approximately 60 years old (adjusted OR = 1.74, 95% CI: 1.15–2.62), and being ADL disabled (adjusted OR: 1.70, 95% CI: 1.04–2.77) are factors that are significantly associated with the risk of having fewer than 20 teeth. Conclusion The analysis suggests that socioeconomic status, dietary intake in early old age, and ADL capacity are associated with the risk of having fewer teeth for the population aged 80 years and above, and the risk factors vary between sexes.

Association between tea types and number of teeth: a cross-sectional study of the Chinese Longitudinal Healthy Longevity Survey

“…Additionally, we found that geographical factors may be associated with oral health, which is consistent with previous findings [ 38 ]. Moreover, men living in rural areas have a higher prevalence of severe oral tooth loss (<10 teeth), which is consistent with our findings using the same dataset analysis [ 23 ]. This may be attributed to the poor geographical accessibility of dental services for men in rural areas, and delayed treatment may contribute to this trend [ 39 – 41 ].…”

“…The CLHLS conducted face-to-face interviews with centenarians (people aged 100 or above) randomly chosen across 23 Chinese provinces. For each centenarian, two local residents (same village, street, town, or city district) were also interviewed [ 23 ]. Predefined age and sex were randomly determined based on the assigned code numbers for matched comparisons of both sexes in each age group [ 7 ].…”

“…Specifically, the survey covered diverse aspects of their lives, including demographics, family structure, diet, chronic diseases, healthcare, smoking and alcohol consumption, early nutrition, and health-related conditions. Refusal rates among the Chinese elderly were minimal due to their enjoyment of interaction and pride in their longevity [ 23 ]. For disabled individuals, proxy respondents (typically spouses or other close family members) were interviewed [ 23 ].…”

“…Refusal rates among the Chinese elderly were minimal due to their enjoyment of interaction and pride in their longevity [ 23 ]. For disabled individuals, proxy respondents (typically spouses or other close family members) were interviewed [ 23 ]. The survey included 15,874 older adults in 23 out of 31 Chinese provinces; among them, 67.4% were aged ≥80 years.…”

Clinical analysis of prophylactic uterine artery embolization combined with double balloon catheter for second-trimester pregnancy termination in cases of complete placenta previa: A retrospective study

“…With the introduction of the three-child policy in China, an increasing number of women with a history of CD or vaginal delivery are opting for another pregnancy. [16] However, as maternal age increases, there is a higher incidence of fetal malformations and intrauterine death. [3,4] Patients presenting with complete placenta previa and PAS, who require an induced abortion during the second-trimester, face a high risk of substantial hemorrhage and infection.…”
