Cadmium (Cd), lead (Pb), and mercury (Hg) cause toxicological renal effects, but the clinical relevance at low-level exposures in general populations is unclear. The objective of this study is to assess the risk of developing end-stage renal disease in relation to Cd, Pb, and Hg exposure.

Accidental falls in the elderly are a major health problem, despite extensive research on risk factors and prevention. Only a limited number of multifactorial, long-term prospective studies have been performed on risk factors for falls in the general elderly population. The aim of this study was to identify risk factors predicting falls in a general elderly population after three and six years, using a prospective design.

Introduction: Contradictory results have been reported on the relationship between orthostatic hypotension (OH) and mild cognitive impairment (MCI). Objective: To study the incidence of MCI and dementia and their relationship to OH and subclinical OH with orthostatic symptoms (orthostatic intolerance). Study design and setting: This study used a prospective general population cohort design and was based on data from the Swedish Good Aging in Skåne study (GÅS-SNAC), they were studied 6 years after baseline of the present study, with the same study protocol at baseline and at follow-up. The study sample comprised 1,480 randomly invited subjects aged 60 to 93 years, and had a participation rate of 82% at follow-up. OH test included assessment of blood pressure and symptoms of OH. Results: The 6-year incidence of MCI was 8%, increasing from 12.1 to 40.5 per 1,000 person-years for men and 6.9 to 16.9 per 1,000 person-years for women aged 60 to >80 years. The corresponding 6-year incidence of dementia was 8%. Orthostatic intolerance during uprising was related to risk for MCI at follow-up (odds ratio [OR] =1.84 [1.20–2.80][95% CI]), adjusted for age and education independently of blood pressure during testing. After stratification for hypertension (HT), the corresponding age-adjusted OR for MCI in the non-HT group was 1.71 (1.10–2.31) and 1.76 (1.11–2.13) in the HT group. Among controls, the proportion of those with OH was 16%; those with MCI 24%; and those with dementia 31% (age-adjusted OR 1.93 [1.19–3.14]). Conclusion: Not only OH, but also symptoms of OH, seem to be a risk factor for cognitive decline and should be considered in the management of blood pressure among the elderly population.

A majority of us will at some point in our lives take care of family members, relatives and friends in need of assistance. How will this affect us? Strain related to life satisfaction (LS) and health related quality of life (HRQoL) among caregivers aged 60 years and older has not been previously studied. The main objective was to describe characteristics of non-caregivers (n=2233) and caregivers (n=369). Further objectives were to examine differences in HRQoL and LS between caregivers and non-caregivers, and between caregivers stratified by level of strain. We analyzed the differences in socio-demographics, social participation, locus of control and symptoms between groups. HRQoL was assessed by Short Form Health Survey (SF-12/PCS and MCS). LS was measured by the Life Satisfaction Index-A (LSI-A). Caregivers were younger, had more years of formal education, more often cohabiting and relied less on powerful others than non-caregivers. One hundred and thirty-three (36%) caregivers reported high strain. In a three-group comparison including non-caregivers and caregivers stratified for strain, high strain was associated with lower SF12-PCS, SF12-MCS and LSI-A (0.014, <0.001 and <0.001, respectively). High strain affects caregivers' HRQoL and LS in a negative way. It is important for the health care sector to consider the possibility that symptoms in a person acting as a caregiver can be related to high perceived strain. A general policy program aiming to identify caregivers and their needs for support is much needed.

Background: For a significant proportion of the older population, increasing age is associated with health problems and worsening health. Older family caregivers are largely responsible for care of next-of-kin living at home, which impacts their own physical and mental health both positively and negatively. However, evidence is insufficient regarding the health situation of older caregivers. The aim of this study was to investigate health-related quality of life (HRQoL) and pain, and their associations, among caregivers aged ≥60 years. Methods: The participants (n = 3444) were recruited from the Swedish National Study on Aging and Care-Blekinge and Good Aging in Skåne during 2001–2004. Participants aged ≥60 years were selected randomly and underwent cognitive tests, with demographic information obtained through questionnaires. The response rate was 60%. A predefined research protocol was used. HRQoL was measured with the Short-Form Health Survey, dimension mental health. Logistic regression models were used to investigate the associations between HRQoL and pain as well as control factors. Results: Family caregiving was reported by 395 (11.5%) of the participants, and 56.7% of the caregivers reported pain. Family caregivers reported lower pain intensity on the Visual Analogue Scale and were younger, on median, than non-caregivers. Irrespective of caregiver status, pain was associated with mental HRQoL. Concerns about personal health and financial status had the strongest associations with mental HRQOL in both groups, but the levels were higher among caregivers. Conclusion: Pain was one factor associated with low HRQoL regardless of family caregiver status and remained important when controlling for factors related to advanced age. This finding remained among family caregivers, though they reported lower pain intensity. Factors other than pain were shown to be important to mental HRQoL and should also be taken into consideration when discussing actions for family caregivers to maintain and improve health and HRQoL.
