Predictors of Falls per Step and Falls per Year At and Away From Home in Glaucoma.

ABSTRACT: OBJECTIVE:To determine where glaucoma patients most often fall and how integrated visual field (IVF) damage affects falls rates per year (falls/year) and per step (falls/step) at and away from home. DESIGN:Prospective, observational cohort study. METHODS:In 225 patients with glaucoma or suspected glaucoma, falls data were collected via calendars, fall location was classified through follow-up questionnaires, and steps taken at and away from home were judged by integrating data from annual week-long accelerometer and GPS trials. Main outcome measures were the association of IVF sensitivity with fall rates per year or step, stratified by location. RESULTS:Participants took more away steps than home steps (2366 vs 1524, P < .001), and differences in away vs home steps did not vary with IVF sensitivity (P = .22). A total of 57% of falls occurred at home, with each home step twice as likely to result in a fall as compared to each away step (rate ratio = 2.02, P < .001). Worse IVF sensitivity was not associated with a higher rate of home falls/year or away falls/year (P > .1 for both), but was associated with a higher rate of home falls/step (rate ratio = 1.34/5 dB worse sensitivity, P = .03) and away falls/step (rate ratio = 1.47/5 dB worse sensitivity, P = .003). CONCLUSIONS:In this glaucoma population, most falls occurred at home, and the risk of any step resulting in a fall was higher at home. Those with greater VF damage were more likely to fall for each step taken both at and away from home. Efforts such as home environmental modification should be considered in the visually impaired to prevent falls while maintaining physical activity.

Project description:BACKGROUND:Modifying a household's food environment by targeting a single retailer type, like supermarkets, has a limited impact on dietary outcomes. This may be because the food environment has a limited impact on shopping behaviors, or because households are not as reliant on supermarkets as we assume. However, our understanding of how households shop for food, especially when considering the use of both food at home (FAH) retailers, such as supermarkets, and away from home retailers (FAFH), such as restaurants, is limited. Thus, understanding how households shop for food is a necessary first step when developing programs to modify food purchasing behavior. METHODS:K-means cluster analysis was used to identify weekly food shopping trip patterns based on the percentage of trips to FAH and FAFH retailers in the 2013 Food Acquisition and Purchase Survey (FoodAPS) dataset (n?=?4665 households). Multinomial logistic regression was used to examine the relationship between shopping trip patterns, household and food environment characteristics. RESULTS:Three patterns emerged: primarily supermarket, primarily supercenter, or mix (i.e. no dominant retailer type, but high FAFH use). Households with incomes below 185% of the federal poverty line were evenly divided between patterns that rely primarily on FAH retailers, and the mix pattern. While nearly 70% of households with incomes above 185% of the federal poverty line are in the mix cluster. Supermarket and superstore availability significantly influenced the likelihood of belonging to those clusters respectively, while having a child, higher income, and attitudes towards healthy meal preparation time or taste significantly influenced the likelihood of belonging to the mix cluster. CONCLUSION:Although lower-income households are more likely to rely primarily on FAH retailers, household's, regardless of income, that primarily utilize FAH retailers show a strong preference for either superstores or supermarkets suggesting a need for interventions to reach both retailer types. However, altering the food environment alone may not be sufficient to discourage use of FAFH retailers as households relying on FAFH retailers are significantly influenced by meal preparation time and healthy food taste.
