Anthropometry, Amplitude of Accommodation, and Spherical Equivalent Refractive Error in a Nigerian Population

Aim . The aim of this study was to investigate the association between anthropometry, amplitude of accommodation assessed by minus-lens to blur (AA PUB ) and push-up to blur (AA MLB ), and spherical equivalent refraction (SEQ). Method . A total of two hundred and one subjects aged between 17 and 70 years with mean age of 34.2 ± 13.3 years, consisting of 93 males and 108 females were recruited for this study. Anthropometric variables were measured with standard instruments like the free-standing rod for height, weighing balance for body weight, and body mass index (BMI) calculated. The refractive error was measured by static retinoscopy and subjective refraction. Result . An inverse correlation was found between age, AA MLB and AA PUB ( r = −0.84, −0.81, both P < 0.0001). BMI increased with age ( r = 0.32, P < 0.0001). There was an inverse correlation between BMI, AA PUB and AA MLB ( r = −0.27, −0.25, both P < 0.0001), respectively. However, the association between SEQ and anthropometry was not significant ( P > 0.05). The AA PUB and AA MLB decreased with age while BMI increased. AA PUB and AA MLB decreased with BMI, but were not affected by the SEQ. Conclusion . BMI increased with age while AA measured by the two methods decreased with age, and BMI increased with decreasing AA.
