RESUMO
BACKGROUND: Water-loss dehydration in older people is associated with increased mortality and disability. We aimed to assess the prevalence of dehydration in older people living in UK long-term care and associated cognitive, functional, and health characteristics. METHODS: The Dehydration Recognition In our Elders (DRIE) cohort study included people aged 65 or older living in long-term care without heart or renal failure. In a cross-sectional baseline analysis, we assessed serum osmolality, previously suggested dehydration risk factors, general health, markers of continence, cognitive and functional health, nutrition status, and medications. Univariate linear regression was used to assess relationships between participant characteristics and serum osmolality, then associated characteristics entered into stepwise backwards multivariate linear regression. RESULTS: DRIE included 188 residents (mean age 86 years, 66% women) of whom 20% were dehydrated (serum osmolality >300 mOsm/kg). Linear and logistic regression suggested that renal, cognitive, and diabetic status were consistently associated with serum osmolality and odds of dehydration, while potassium-sparing diuretics, sex, number of recent health contacts, and bladder incontinence were sometimes associated. Thirst was not associated with hydration status. CONCLUSIONS: DRIE found high prevalence of dehydration in older people living in UK long-term care, reinforcing the proposed association between cognitive and renal function and hydration. Dehydration is associated with increased mortality and disability in older people, but trials to assess effects of interventions to support healthy fluid intakes in older people living in residential care are needed to enable us to formally assess causal direction and any health benefits of increasing fluid intakes.

BACKGROUND: The prevalence of overweight and obesity is increasing amongst women of child bearing age. Maternal obesity has implications for both mother and baby including increased health risks from gestational hypertensive disorders, caesarean section and stillbirth. Despite the increasing prevalence of maternal obesity little is known of the experiences of these women within the health care system. The aim of this research was to investigate the perspectives of pregnant women with a body mass index (BMI) of ≥30kg/m(2) receiving antenatal care. METHODS: A qualitative study using individual interviews was undertaken. Sixteen pregnant women with a BMI ≥30kg/m(2) participated. Interviews were audio recorded, transcribed, cross checked for consistency and then entered into a word processing document for analysis. Data was analysed using Interpretative Phenomenological Analysis. In any phenomenological study the researcher's objective is to elicit the participant's views on their lived experiences. FINDINGS: Four major themes emerged: (1) obese during pregnancy as part of a long history of obesity; (2) lack of knowledge of the key complications of obesity for both mother and child; (3) communication about weight and gestational weight gain can be conflicting, confusing and judgmental; (4) most women are motivated to eat well during pregnancy and want help to do so. CONCLUSION: Specialist lifestyle interventions for obese women should be a priority in antenatal care. Extra support is required to assist obese women in pregnancy achieve recommended nutritional and weight goals. Health professionals should approach the issue of maternal obesity in an informative but non-judgmental way.
