Abstract：
BACKGROUND: The presence of sensory impairment among older age cohorts exerts a significant impact on both individuals and society generally. Although the impact of dietary patterns on health is vital across all stages of life, there still a paucity of comprehensive research on the association between dietary variety and sensory impairments.
OBJECTIVE: To investigate the potential relationship between dietary diversity and the prevalence of visual and hearing impairment or dual sensory impairments (visual and hearing impairment) among the oldest old population.
METHODS: This is a cross-sectional study relied on data obtained from the 2018 survey conducted by the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Subjects aged 80 and older with complete vision and hearing data were included in the study. Multivariate logistic regression models were developed to examine the association between dietary components and visual and hearing impairment while controlling for age, gender, socioeconomic demographic factors, living habits, other food habits, and general health status.
RESULTS: The study included 10,093 participants, with an average age of 92.29 ± 7.75 years. Vision and hearing function were assessed based on the ability to distinguish the direction of the break in the circle and the requirement for hearing aids, respectively. Upon controlling for confounding variables, individuals with a greater Dietary Diversity Score (DDS, the number of food groups, range: 1-11) had a reduced likelihood of experiencing visual impairment (odds ratio [OR] = 0.944, 95% confidence interval [CI], 0.915-0.974) and dual sensory impairment (OR = 0.930, 95% CI, 0.905-0.955). In comparison to the low dietary variety group (insufficient dietary diversity, DDS < 4), the high dietary diversity group (sufficient dietary diversity, DDS ≥ 4) exhibited a decreased risk of visual impairment (OR = 0.820, 95% CI, 0.713-0.944) and dual sensory impairment (OR = 0.751, 95% CI, 0.667-0.846). However, no statistically significant correlation was observed between dietary diversity and the presence of only hearing impairment (OR = 0.924, 95% CI, 0.815-1.047) (P < 0.05). CONCLUSIONS AND IMPLICATIONS: The synthesis of research findings suggests that following diverse dietary patterns and healthy nutritional practices may be an effective and affordable way to prevent age-related decline in visual impairment and dual sensory impairment.

摘要：
背景：老年人群感觉障碍的存在对个人和社会都有显著影响。尽管饮食模式对健康的影响在生命的所有阶段都至关重要，关于饮食多样性与感觉障碍之间关系的综合研究仍然很少。
目的：调查年龄最大的老年人群的饮食多样性与视觉和听力障碍或双重感觉障碍（视觉和听力障碍）患病率之间的潜在关系。
方法：这是一项横断面研究，基于中国纵向健康长寿调查（CLHLS）进行的2018年调查获得的数据。研究包括80岁及以上具有完整视力和听力数据的受试者。建立了多变量逻辑回归模型，以检查饮食成分与视力和听力障碍之间的关系，同时控制年龄，性别,社会经济人口因素，生活习惯,其他饮食习惯,和一般健康状况。
结果：该研究包括10,093名参与者，平均年龄92.29±7.75岁。视觉和听力功能是根据区分圆圈中断裂方向的能力和对助听器的要求进行评估的。分别。在控制混杂变量后，饮食多样性评分较高的个体(DDS，食物组的数量，范围：1-11)视力障碍的可能性降低(比值比[OR]=0.944，95%置信区间[CI]，0.915-0.974)和双重感觉障碍(OR=0.930，95%CI，0.905-0.955)。与低膳食品种组(膳食多样性不足，DDS<4),高膳食多样性组(足够的膳食多样性，DDS≥4）表现出视觉障碍（OR=0.820，95％CI，0.713-0.944）和双重感觉障碍（OR=0.751，95％CI，0.667-0.846）的风险降低。然而,饮食多样性与听力障碍的存在无统计学意义（OR=0.924，95％CI，0.815-1.047）（P<0.05）。结论和意义：研究结果的综合表明，遵循不同的饮食模式和健康的营养习惯可能是预防与年龄相关的视觉障碍和双重感觉障碍下降的有效和负担得起的方法。
