To determine the near vision spectacle coverage and barriers to obtaining near vision correction among adults aged 35 years and older in the Cape Coast Metropolis of Ghana.
A population-based cross-sectional study design was adopted and 500 out of 576 participants aged 35 years and older were examined from 12 randomly selected clusters in Cape Coast, Ghana. All participants underwent a comprehensive eye examination which included: distance and near visual acuities measurements and external and internal ocular health assessments. Distance and near refractions were performed using subjective refraction technique. Information on participants' demographics, near vision correction status, near visual needs and barriers to acquiring near vision correction were obtained through a questionnaire administered as part of the study.
The mean age of participants was 52.3±10.3 years of whom 280 (56%) were females and 220 (44%) were males. The near vision spectacle coverage was 25%, 33% "met need" for near vision correction in the presbyopic population, and 64% unmet need in the entire study population. After controlling for other variables, age (5 and 6 decades) and educational level were associated with "met need" for near vision correction (OR=2.7 (1.55-4.68), p =0.00, and OR=2.36 (1.18-4.72), p=0.02 respectively). Among those who needed but did not have near vision correction, 64 (26%) did not feel the need for correction, 55 (22%) stated that they were unaware of available interventions, and 53 (21%) found the cost of near vision correction prohibitive.
There was a low near vision spectacle coverage in this population which suggests the need for strategies on health education and promotion to address the lack of awareness of spectacle need and cost of services.
确定加纳海岸角大都会35岁及以上成年人的近视力眼镜覆盖率以及获得近视力矫正的障碍。
采用基于人群的横断面研究设计,从加纳海岸角12个随机选取的群组中检查了576名35岁及以上参与者中的500名。所有参与者均接受了全面的眼部检查,包括:远视力和近视力测量以及眼外部和内部健康评估。使用主观验光技术进行远视力和近视力验光。通过作为研究一部分发放的问卷获取参与者的人口统计学信息、近视力矫正状况、近视力需求以及获得近视力矫正的障碍。
参与者的平均年龄为52.3±10.3岁,其中280名(56%)为女性,220名(44%)为男性。近视力眼镜覆盖率为25%,老花人群中近视力矫正“满足需求”的比例为33%,整个研究人群中未满足需求的比例为64%。在控制其他变量后,年龄(50岁和60岁)和教育水平与近视力矫正“满足需求”相关(比值比分别为2.7(1.55 - 4.68),p = 0.00,以及2.36(1.18 - 4.72),p = 0.02)。在那些需要但没有近视力矫正的人中,64名(26%)不觉得有矫正的必要,55名(22%)表示他们不知道有可用的干预措施,53名(21%)认为近视力矫正的费用过高。
该人群的近视力眼镜覆盖率较低,这表明需要制定健康教育和促进策略,以解决对眼镜需求和服务费用缺乏认识的问题。
