The association of fear of falling and physical and mental Health-Related Quality of Life (HRQoL) among community-dwelling older persons; a cross-sectional study of Urban Health Centres Europe (UHCE).

BACKGROUND: The share of people over 80 years in the European Union is estimated to increase two-and-a-half-fold from 2000 to 2100. A substantial share of older persons experiences fear of falling. This fear is partly associated with a fall in the recent past. Because of the associations between fear of falling, avoiding physical activity, and the potential impact of those on health, an association between fear of falling and low health-related quality of life, is suggested. This study examined the association of fear of falling with physical and mental Health-Related Quality of Life (HRQoL) among community-dwelling older persons in five European countries. METHODS: A cross-sectional study was conducted using baseline data of community-dwelling persons of 70 years and older participating in the Urban Health Centers Europe project in five European countries: United Kingdom, Greece, Croatia, the Netherlands and Spain. This study assessed fear of falling with the Short Falls Efficacy Scale-International and HRQoL with the 12-Item Short-Form Health Survey. The association between low, moderate or high fear of falling and HRQoL was examined using adjusted multivariable linear regression models. RESULTS: Data of 2189 persons were analyzed (mean age 79.6 years; 60.6% females). Among the participants, 1096 (50.1%) experienced low fear of falling; 648 (29.6%) moderate fear of falling and 445 (20.3%) high fear of falling. Compared to those who reported low fear of falling in multivariate analysis, participants who reported moderate or high fear of falling experienced lower physical HRQoL (ß = -6.10, P < 0.001 and ß = -13.15, P < 0.001, respectively). In addition, participants who reported moderate or high fear of falling also experienced lower mental HRQoL than those who reported low fear of falling (ß = -2.31, P < 0.001 and ß = -8.80, P < 0.001, respectively). CONCLUSIONS: This study observed a negative association between fear of falling and physical and mental HRQoL in a population of older European persons. These findings emphasize the relevance for health professionals to assess and address fear of falling. In addition, attention should be given to programs that promote physical activity, reduce fear of falling, and maintain or increase physical strength among older adults; this may contribute to physical and mental HRQoL.

Faecal water content and egg survival of goat gastro-intestinal strongyles under dry tropical conditions in Guadeloupe.

Faeces from naturally infected goats were deposited on a natural grassland during the dry season in Guadeloupe (French West Indies) at different times throughout the day. The grass was either 7 or 20-30 cm tall. After a period of between several hours and 7 days, the number of viable strongyle eggs and the faecal water content were measured. Faecal temperature was recorded continuously. Faecal temperature was greater than 40 degrees-45 degrees C at midday and dehydration was rapid between 8 a.m. and 2 p.m. Egg mortality was greater on short than on tall grass and higher in morning than in evening deposits. Minimal faecal water content during the first 36 h explained the 74%, 55% and 38% mortality rate for eggs of Oesophagostomum columbianum (OC), Haemonchus contortus (HC) and Trichostrongylus colubriformis (TC), respectively. In all, 5%-22% of the eggs of the latter species remained viable in a state of anhydrobiosis after 7 days on the ground. A delay of only 2 days between goat departure and irrigation would be sufficient to ensure that greater than 95% of O. columbianum and H. contortus eggs and 70% of T. colubriformis eggs are destroyed.
