Prevalence, Characteristics, and Risk Factors of Moderate or High Hyperopia among Multiethnic Children 6 to 72 Months of Age: A Pooled Analysis of Individual Participant Data.

ABSTRACT: PURPOSE:To describe the prevalence, ocular characteristics, and associated risk factors of moderate to high hyperopia in early childhood. DESIGN:Pooled analysis of individual participant data from population-based studies. PARTICIPANTS:Six- to 72-month-old multiethnic children who participated in 4 population-based studies of pediatric eye diseases. METHODS:The pooled studies conducted comparable parental interviews and ocular examinations including cycloplegic autorefraction. Presence of hyperopia was defined based on cycloplegic refractive error in the worse eye. Multivariate analyses were performed to evaluate the association of potential risk factors with hyperopia risk. MAIN OUTCOME MEASURES:Prevalence and odds ratios of moderate to high hyperopia (?4.0 diopters [D]). RESULTS:Cycloplegic refraction was completed in 15?051 children 6 to 72 months of age. Among these children, the overall prevalence of moderate to high hyperopia (?4.0 D) in the worse eye was 3.2% (95% confidence interval, 2.9%-3.5%), accounting for 15.6% of all hyperopia (?2.0 D). Among children with moderate to high hyperopia, both eyes were affected in 64.4%, 28.9% showed spherical anisometropia of 1.0 D or more, and 19.5% showed astigmatism of 1.5 D or more. Among 36- to 72-month-old children with moderate to high hyperopia, 17.6% wore glasses. Prevalence of moderate to high hyperopia was slightly less in 12- to 23-month-old children and was relatively stable in children 24 months of age and older. Non-Hispanic and Hispanic white race and ethnicity, family history of strabismus, maternal smoking during pregnancy, and being a participant in the United States studies were associated with a higher risk of moderate to high hyperopia (P < 0.05). CONCLUSIONS:By assembling similarly designed studies, our consortium provided robust estimates of the prevalence of moderate to high hyperopia in the general population and showed that in 6- to 72-month-old children, moderate to high hyperopia is not uncommon and its prevalence does not decrease with age. Risk factors for moderate to high hyperopia differ from those for low to moderate hyperopia (2.0-<4.0 D) in preschool children, with family history of strabismus and maternal smoking during pregnancy more strongly associated with moderate to high hyperopia than low to moderate hyperopia.

Project description:PurposeThis article provides recommendations for screening children aged 36 to younger than 72 months for eye and visual system disorders. The recommendations were developed by the National Expert Panel to the National Center for Children's Vision and Eye Health, sponsored by Prevent Blindness, and funded by the Maternal and Child Health Bureau of the Health Resources and Services Administration, United States Department of Health and Human Services. The recommendations describe both best and acceptable practice standards. Targeted vision disorders for screening are primarily amblyopia, strabismus, significant refractive error, and associated risk factors. The recommended screening tests are intended for use by lay screeners, nurses, and other personnel who screen children in educational, community, public health, or primary health care settings. Characteristics of children who should be examined by an optometrist or ophthalmologist rather than undergo vision screening are also described.ResultsThere are two current best practice vision screening methods for children aged 36 to younger than 72 months: (1) monocular visual acuity testing using single HOTV letters or LEA Symbols surrounded by crowding bars at a 5-ft (1.5 m) test distance, with the child responding by either matching or naming, or (2) instrument-based testing using the Retinomax autorefractor or the SureSight Vision Screener with the Vision in Preschoolers Study data software installed (version 2.24 or 2.25 set to minus cylinder form). Using the Plusoptix Photoscreener is acceptable practice, as is adding stereoacuity testing using the PASS (Preschool Assessment of Stereopsis with a Smile) stereotest as a supplemental procedure to visual acuity testing or autorefraction.ConclusionsThe National Expert Panel recommends that children aged 36 to younger than 72 months be screened annually (best practice) or at least once (accepted minimum standard) using one of the best practice approaches.

Project description:Kidney recipients have anal cancer rates 3 times higher than the general population in Australia and New Zealand. High-risk human papillomavirus (HPV) genotypes are implicated in the majority of anal cancers. Establishing the epidemiology of anal HPV infection and precursors of anal cancer in transplant recipient populations is 1 consideration in any potential screening program. The Transplant and Anal Neoplasia Study is a cross-sectional study of the prevalence of anal cytological abnormalities and HPV deoxyribonucleic acid in kidney transplant recipients, as well as evaluating the acceptability of an anal cancer screening intervention. The study aims to recruit 100 kidney transplant recipients, older than 18 years, in Australia. Transplant recipients attending for a protocol biopsy at 3 and 12 months and annually posttransplant are approached to participate. Participants undergo an anal swab, which is then analyzed using liquid-based cytological examination and tested for the detection of 37 anogenital HPV deoxyribonucleic acid genotypes. Participants also complete a demographic and behavioral questionnaire that covers sexual behavior, history of anal symptoms, and possible anal cancer risk factors. Associations will be tested using multiple regression analysis. Recruitment for the study began in 2015 and is ongoing. To date, 96 (77%) of 125 kidney transplant recipients approached have consented to the study. The mean age is 48 (median, 47 y; range, 20-76 y), 59% are male, and Northwest European (58%) represented the largest ethnic group. No participants self-identified as Aboriginal or Torres Strait Islander. High consent rates and positive qualitative results suggest that a larger screening program may be well received by kidney transplant recipients, with increased resources and some modification to the timing of approach. Further results of the study will inform the possible implementation of a larger screening trial for prevention of anal cancers in kidney and other solid organ transplant recipients.
