Prenatal alcohol exposure and childhood balance ability:findings from a UK birth cohort study

OBJECTIVE: To investigate the association of prenatal alcohol exposure with balance in10-year-old children. DESIGN: Population-based prospective longitudinal study. SETTING: Former Avon region of UK (Southwest England). PARTICIPANTS: 6915 children from the Avon Longitudinal Study of Parents and Children who had a balance assessment at age 10 and had data on maternal alcohol consumption. OUTCOME MEASURES: 3 composite balance scores: dynamic balance (beam-walking), static balance eyes open, static balance eyes closed (heel-to-toe balance on a beam and standing on one leg, eyes open or closed). RESULTS: Most mothers (95.5%) consumed no-to-moderate amounts (3-7 glasses/week) of alcohol during pregnancy. Higher total-alcohol consumption was associated with maternal-social advantage, whereas binge drinking (≥4 units/day) and abstinence were associated with maternal social disadvantage. No evidence was found of an adverse effect of maternal-alcohol consumption on childhood balance. Higher maternal-alcohol use during pregnancy was generally associated with better offspring outcomes, with some specific effects appearing strong (static balance eyes open and moderate total alcohol exposure at 18 weeks, adjusted OR 1.23 (95% CI 1.01 to 1.49); static balance eyes closed and moderate total alcohol exposure at 18 weeks, adjusted OR 1.25 (95% CI 1.06 to 1.48). Similar results were found for both paternal and postnatal maternal alcohol exposure. A Mendelian-randomization approach was used to estimate the association between maternal genotype and offspring balance using the non-synonymous variant rs1229984*A (ADH1B) to proxy for lower maternal alcohol consumption; no strong associations were found between this genotype/proxy and offspring balance. CONCLUSIONS: No evidence was found to indicate that moderate maternal alcohol consumption in this population sample had an adverse effect on offspring balance at age 10. An apparent beneficial effect of higher total maternal alcohol consumption on offspring balance appeared likely to reflect residual confounding.

Balance ability of 7 and 10 year old children in the population:results from a large UK birth cohort study

OBJECTIVE: The literature contains many reports of balance function in children, but these are often on atypical samples taken from hospital-based clinics and may not be generalisable to the population as a whole. The purpose of the present study is to describe balance test results from a large UK-based birth cohort study. METHODS: Data from the Avon Longitudinal Study of Parents and Children (ALSPAC) were analysed. A total of 5402 children completed the heel-to-toe walking test at age 7 years. At age 10 years, 6915 children underwent clinical tests of balance including beam-walking, standing heel-to-toe on a beam and standing on one leg. A proportion of the children returned to the clinic for retesting within 3 months allowing test-retest agreement to be measured. RESULTS: Frequency distributions for each of the balance tests are given. Correlations between measures of dynamic balance at ages 7 and 10 years were weak. The static balance of 10 year old children was found to be poorer with eyes closed than with eyes open, and poorer in boys than in girls for all measures. Balance on one leg was poorer than heel-to-toe balance on a beam. A significant learning effect was found when first and second attempts of the tests were compared. Measures of static and dynamic balance appeared independent. Consistent with previous reports in the literature, test-retest reliability was found to be low. CONCLUSIONS: This study provides information about the balance ability of children aged 7 and 10 years and provides clinicians with reference data for balance tests commonly used in the paediatric clinic.

Envelhecimento e Diabetes Mellitus Tipo 2: estudo dos efeitos do exercício físico no comportamento postural e capacidade funcional de pacientes com Diabetes Mellitus Tipo 2

A Diabetes Mellitus é uma patologia fortemente associada ao processo de envelhecimento, afectando cada vez mais pessoas em todo o mundo. Uma das maiores complicações observadas nesta população prende-se com a diminuição do controlo postural e da capacidade funcional relacionada com a locomoção. O exercício físico tem sido apontado como uma das formas de prevenção e tratamento deste problema, no entanto existe ainda uma lacuna no conhecimento sobre o modo mais indicado de exercício. O presente pretende avaliar os efeitos de um programa de exercício físico aeróbio sobre o controlo postural e a capacidade funcional de pacientes portadores de Diabetes Mellitus Tipo 2. A amostra do estudo foi composta por 30 sujeitos de ambos os sexos, distribuídos por um grupo experimental (n=16) a quem foi aplicado o programa de exercício físico, e por um grupo de controlo (n=14), o qual não usufruiu de qualquer programa de exercício físico. O programa teve a duração de 12 semanas de treino, e uma frequência de 3 vezes por semana. Os participantes mantiveram-se em movimento constante durante as sessões tendo os exercícios realizados possuído uma forte componente dinâmica. Foi avaliado o controlo postural através de uma plataforma de forças e a capacidade funcional através de um conjunto de cinco testes funcionais. Os resultados obtidos revelam não terem existido diferenças estatisticamente significativas (p>0,05) na interacção entre grupos e momentos de avaliação nas variáveis analisadas, com excepção para a performance no Timed Get Up & Go Test, a qual melhorou significativamente (p<0,05) no grupo experimental. Estes dados sugerem que a especificidade tanto estática como dinâmica dos exercícios e a intensidade a que são realizados são factores fundamentais a ter em consideração no planeamento de programas de exercício físico, com vista à melhoria quer do controlo postural quer da capacidade funcional em portadores de Diabetes Mellius Tipo 2. ABSTRACT: Diabetes Mellitus is a disease associated with aging, affecting a growing number of people all over the world. One of the major concerns in this population relates to the decline of postural control and functional capacity. Exercise has been suggested as one way of preventing and treating this problem, however little is known about the most appropriate mode of exercise. This study evaluates the effect of an aerobic exercise program on postural control and functional capacity of patients with Type 2 Diabetes Mellitus. The sample consisted of 30 subjects, over an experimental group (n = 16) applied to an exercise program, and a control group (n = 14), that received no treatment. The program lasted 12 weeks, three times a week. Participants remained in constant motion during the sessions and the exercises performed had a strong dynamic component. Postural control was assessed using a force platform and functional capacity through a set of five functional tests. The results show that there were no statistically significant differences (p>O, O5) in group/moment interaction in the variables analyzed, except for the Timed Get Up & Go Test, which improved significantly (p <0,05) in the experimental group. These data suggest that both static and dynamic specificity and intensity of exercises are key factors in exercises programs planning, targeted to improve both postural control and functional capacity in patients with Type 2 Diabetes Mellius.

Work/Family Balance: HRM Policy and Practice in Australia

An employee's inability to balance work and family responsibilities has resulted in an increase in stress related illnesses. Historically, research into the nexus between work and family has primarily focused on the work/family conflict relationship, predominately investigating the impact of this conflict on parents, usually mothers. To date research has not sufficiently examined the human resource management practices that enable all parents to achieve a balance between their work and family lives. This paper explores the relationship between contemporary family friendly HRM policies and employed parents perceptions of work/family enhancement, work/family satisfaction, propensity to turnover, and work/family conflict. Self-report questionnaire data from 326 men and women is analysed and discussed to enable organisations to consider the use of family friendly policies and thus create a convergence between the well-being of employees and the effectiveness of the organisation.

Aging, retirement, and changes in physical activity : prospective cohort findings from the globe study

There is increased recognition that determinants of health should be investigated in a life-course perspective. Retirement is a major transition in the life course and offers opportunities for changes in physical activity that may improve health in the aging population. The authors examined the effect of retirement on changes in physical activity in the GLOBE Study, a prospective cohort study known by the Dutch acronym for "Health and Living Conditions of the Population of Eindhoven and surroundings," 1991–2004. They followed respondents (n = 971) by postal questionnaire who were employed and aged 40–65 years in 1991 for 13 years, after which they were still employed (n = 287) or had retired (n = 684). Physical activity included 1) work-related transportation, 2) sports participation, and 3) nonsports leisure-time physical activity. Multinomial logistic regression analyses indicated that retirement was associated with a significantly higher odds for a decline in physical activity from work-related transportation (odds ratio (OR) = 3.03, 95% confidence interval (CI): 1.97, 4.65), adjusted for sex, age, marital status, chronic diseases, and education, compared with remaining employed. Retirement was not associated with an increase in sports participation (OR = 1.12, 95% CI: 0.71, 1.75) or nonsports leisure-time physical activity (OR = 0.80, 95% CI: 0.54, 1.19). In conclusion, retirement introduces a reduction in physical activity from work-related transportation that is not compensated for by an increase in sports participation or an increase in nonsports leisure-time physical activity.

Contrast sensitivity changes due to glaucoma and normal aging: low-spatial-frequency losses in both magnocellular and parvocellular pathways

PURPOSE: To explore the effects of glaucoma and aging on low-spatial-frequency contrast sensitivity by using tests designed to assess performance of either the magnocellular (M) or parvocellular (P) visual pathways. METHODS: Contrast sensitivity was measured for spatial frequencies of 0.25 to 2 cyc/deg by using a published steady- and pulsed-pedestal approach. Sixteen patients with glaucoma and 16 approximately age-matched control subjects participated. Patients with glaucoma were tested foveally and at two midperipheral locations: (1) an area of early visual field loss, and (2) an area of normal visual field. Control subjects were assessed in matched locations. An additional group of 12 younger control subjects (aged 20-35 years) were also tested. RESULTS: Older control subjects demonstrated reduced sensitivity relative to the younger group for the steady (presumed M)- and pulsed (presumed P)-pedestal conditions. Sensitivity was reduced foveally and in the midperiphery across the spatial frequency range. In the area of early visual field loss, the glaucoma group demonstrated further sensitivity reduction relative to older control subjects across the spatial frequency range for both the steady- and pulsed-pedestal tasks. Sensitivity was also reduced in the midperipheral location of "normal" visual field for the pulsed condition. CONCLUSIONS: Normal aging results in a reduction of contrast sensitivity for the low-spatial-frequency-sensitive components of both the M and P pathways. Glaucoma results in a further reduction of sensitivity that is not selective for M or P function. The low-spatial-frequency-sensitive channels of both pathways, which are presumably mediated by cells with larger receptive fields, are approximately equivalently impaired in early glaucoma.
