Anthropomorphic measurements and general and ocular parameters in adult Chinese: the Beijing Eye Study

Purpose: To determine whether anthropomorphic measurements are associated with ocular and general parameters. Methods: The population-based Beijing Eye Study, which included 4439 participants (age > 40 years) out of 5324 individuals invited to be examined in 2001, was repeated in 2006 with 3251 (73.2% of 4439, or 61.1% of 5324) participants. The anthropomorphic measurements body height and weight, socioeconomic variables and ocular parameters were evaluated. Results: Of the 3251 individuals included in the study, measurements of body height and weight were available for 3214 (98.9%) participants. In multivariate analysis, body height was significantly associated with the systemic parameters higher level of education (p = 0.004), higher income (p < 0.001), lower body mass index (p < 0.001), lower systolic blood pressure (p = 0.012), higher diastolic blood pressure (p < 0.001), male gender (p < 0.001), lower age (p < 0.001) and living in an urban region (p < 0.001), and with the ocular parameter of a deep anterior chamber (p < 0.001). The association between marked hyperopia and low body height was statistically marginal (p = 0.11). Conclusion: In adult Chinese, body height is associated with higher level of education, higher income, lower systolic blood pressure, higher diastolic blood pressure and lower body mass index, in addition to living in an urban region and being male. From an ophthalmic point of view, tall individuals had deeper anterior chambers. There was a tendency towards lower body height and marked hyperopia. Because the socioeconomic, systemic and ocular parameters examined influence the occurrence and therapy of ocular diseases, these data may be helpful in the assessment of risk factors and in the diagnosis and treatment of ocular diseases.
