Background: Physical activity is associated with improved health outcomes in many populations. It is assumed that physical activity levels in the rheumatoid arthritis (RA) population may be reduced as a result of symptoms of the disease. The objective of this review is to establish the current evidence base for levels of physical activity in the RA population. Methods: A systematic review was performed of 7 databases (Emabase, MEDLINE, AMED, Biomedical Reference Collection Expanded, CINAHL, Nursing and Allied Health Collection, and SportsDiscus) up to February 2011 to examine the evidence in the area. Results: One hundred and thirty-six studies were identified through electronic searching. One hundred and six were excluded based on title and/or abstract analysis and a further 14 were excluded based on full text analysis. Sixteen studies meeting the criteria were deemed suitable for inclusion. The results of the included studies indicate that the level of physical activity may be lower among individuals with RA when compared with healthy controls or normative data. Conclusions: There are a number of methodological considerations at play within the studies reviewed which prohibits definitive conclusion on the physical activity levels of this population group. Given the known health benefits of physical activity, further research in this area appears indicated.

Objective. To evaluate a 12-week group-based lifestyle intervention programme for women with prediabetes following gestational diabetes (GDM). Design. A two-group, mixed methods randomized controlled trial in which 50 women with a history of GDM and abnormal glucose tolerance postpartum were randomly assigned to intervention (n = 24) or wait control (n = 26) and postintervention qualitative interviews with participants. Main Outcome Measures. Modifiable biochemical, anthropometric, behavioural, and psychosocial risk factors associated with the development of type 2 diabetes. The primary outcome variable was the change in fasting plasma glucose (FPG) from study entry to one-year follow-up. Results. At one-year follow-up, the intervention group showed significant improvements over the wait control group on stress, diet self-efficacy, and quality of life. There was no evidence of an effect of the intervention on measures of biochemistry or anthropometry; the effect on one health behaviour, diet adherence, was close to significance. Conclusions. Prevention programmes must tackle the barriers to participation faced by this population; home-based interventions should be investigated. Strategies for promoting long-term health self-management need to be developed and tested.

Objective. Measuring physical activity in people with rheumatoid arthritis (RA) is of great importance in light of the increased mortality in this population due to cardiovascular disease. Validation of activity monitors in specific populations is recommended to ensure the accuracy of physical activity measurement. Thus, the purpose of this study was to determine the validity of the SenseWear Pro3 Armband (SWA) as a measure of physical activity during activities of daily living (ADL) in people with RA. Methods. Fourteen subjects (8 men and 6 women) with a diagnosis of RA were recruited from rheumatology clinics at the Mid-Western Regional Hospitals, Limerick, Ireland. Participants undertook a series of ADL of varying intensities. The SWA was compared to the criterion measures of the Oxycon Mobile indirect calorimetry system (energy expenditure in kJ) and of manual video observation (step count). Bland and Altman, intraclass correlation coefficient (ICC), and correlation analyses were done using SPSS, version 19.0. Results. The SWA showed substantial agreement (ICC 0.717, P < 0.001) and a strong relationship (Pearson's correlation coefficient ‫؍‬ 0.852) compared with the criterion measure when estimating energy expenditure during ADL. However, it was found that the SWA overestimated energy expenditure, particularly at higher intensity levels. The ability of the SWA to estimate step counts during ADL was poor (ICC 0.304, P ‫؍‬ 0.038). Conclusion. The SWA can be considered a valid tool to estimate energy expenditure during ADL in the RA population; however, attention should be paid to its tendency to overestimate energy expenditure.

Objectives. The aim of the present study was to qualitatively explore users' experiences of home monitoring of health with specific regard to physical activity monitors. Methods. Fourteen participants were randomly selected from a larger sample of individuals with rheumatoid arthritis (RA) who had taken part in a physical activity monitoring study and had worn two physical activity monitors for seven days in their homes. These individuals were assigned to one of two focus groups. Each focus group lasted for between 40 minutes and an hour and was audio-recorded. A semi-structured questioning route was used, followed by subsequent theoretical thematic analysis. Results. No statistically significant differences were noted in the demographic factors between those who took part in the focus groups and the entire RA sample. Three distinct themes were identified: i) Experiences of having health monitored in the home, which was found to be largely positive; ii) Experiences of use of specific technology to monitor physical activity, which was generally reported as unobtrusive and not to impact significantly negatively on their daily life; iii) Perceptions and experiences of physical activity and exercise, which monitoring was reported to facilitate focusing on physical activity choices. Conclusions. These focus groups were the first to highlight the perceptions held by individuals with RA regarding home monitoring and, in particular, physical activity monitoring. This has implications for those planning interventions for this group which involve home monitoring. Interesting findings were also highlighted regarding the perceptions and understanding of physical activity and exercise among people with RA.

BackgroundThere is no consensus on the effect of gestational diabetes mellitus (GDM) on health-related quality of life (HRQOL) for the mother in the short or long term. In this study we examined HRQOL in a group of women who had GDM in the index pregnancy 2 to 5 years previously and compared it to a group of women with normal glucose tolerance (NGT) in the index pregnancy during the same time period.MethodsThe sample included 234 women who met International Association of Diabetes Study Groups (IADPSG) criteria for GDM in the index pregnancy and 108 who had NGT. The sample was drawn from the ATLATIC-DIP (Diabetes In Pregnancy) cohort – a network of antenatal centers along the Irish Atlantic seaboard serving a population of approximately 500,000 people. HRQOL was measured using the visual analogue component of the EQ-5D-3 L instrument in a cross-sectional survey.ResultsThe difference in HRQOL between GDM and NGT groups was not significant when adjusted for the effects of the covariates. HRQOL was negatively affected by increased BMI and abnormal glucose tolerance post-partum in the NGT group. Moderate alcohol consumption was positively associated with HRQOL in the NGT group only. The negative association with smoking on HRQOL was substantially higher in the GDM group.ConclusionsA diagnosis of GDM does not appear to have an adverse effect on HRQOL, 2 to 5 years after the index pregnancy. On the contrary, its diagnosis might lead to the development of coping strategies, which, consequently attenuates the adverse effect of the subsequent acquisition of abnormal glucose tolerance post-partum on HRQOL. Women whose pregnancy was affected by GDM are more susceptible to the adverse effects on HRQOL of alcohol use and tobacco smoking.Electronic supplementary materialThe online version of this article (doi:10.1186/s12884-015-0705-y) contains supplementary material, which is available to authorized users.
