Community based yoga classes for type 2 diabetes: an exploratory randomised controlled trial.

BACKGROUND: Yoga is a popular therapy for diabetes but its efficacy is contested. The aim of this study was to explore the feasibility of researching community based yoga classes in Type 2 diabetes with a view to informing the design of a definitive, multi-centre trial METHODS: The study design was an exploratory randomised controlled trial with in-depth process evaluation. The setting was two multi-ethnic boroughs in London, UK; one with average and one with low mean socio-economic deprivation score. Classes were held at a sports centre or GP surgery. Participants were 59 people with Type 2 diabetes not taking insulin, recruited from general practice lists or opportunistically by general practice staff. The intervention group were offered 12 weeks of a twice-weekly 90-minute yoga class; the control group was a waiting list for the yoga classes. Both groups received advice and leaflets on healthy lifestyle and were encouraged to exercise. Primary outcome measure was HbA1c. Secondary outcome measures included attendance, weight, waist circumference, lipid levels, blood pressure, UKPDS cardiovascular risk score, diabetes-related quality of life (ADDQoL), and self-efficacy. Process measures were attendance at yoga sessions, self-reported frequency of practice between taught sessions, and qualitative data (interviews with patients and therapists, ethnographic observation of the yoga classes, and analysis of documents including minutes of meetings, correspondence, and exercise plans). RESULTS: Despite broad inclusion criteria, around two-thirds of the patients on GP diabetic registers proved ineligible, and 90% of the remainder declined to participate. Mean age of participants was 60 +/- 10 years. Attendance at yoga classes was around 50%. Nobody did the exercises regularly at home. Yoga teachers felt that most participants were unsuitable for 'standard' yoga exercises because of limited flexibility, lack of basic fitness, co-morbidity, and lack of confidence. There was a small fall in HbA1c in the yoga group which was not statistically significant and which was not sustained six months later, and no significant change in other outcome measures. CONCLUSION: The benefits of yoga in type 2 diabetes suggested in some previous studies were not confirmed. Possible explanations (apart from lack of efficacy) include recruitment challenges; practical and motivational barriers to class attendance; physical and motivational barriers to engaging in the exercises; inadequate intensity and/or duration of yoga intervention; and insufficient personalisation of exercises to individual needs. All these factors should be considered when designing future trials. TRIAL REGISTRATION: National Research Register (1410) and Current Controlled Trials (ISRCTN63637211).

A systematic review of mental disorder, suicide, and deliberate self harm in lesbian, gay and bisexual people.

BACKGROUND: Lesbian, gay and bisexual (LGB) people may be at higher risk of mental disorders than heterosexual people. METHOD: We conducted a systematic review and meta-analysis of the prevalence of mental disorder, substance misuse, suicide, suicidal ideation and deliberate self harm in LGB people. We searched Medline, Embase, PsycInfo, Cinahl, the Cochrane Library Database, the Web of Knowledge, the Applied Social Sciences Index and Abstracts, the International Bibliography of the Social Sciences, Sociological Abstracts, the Campbell Collaboration and grey literature databases for articles published January 1966 to April 2005. We also used Google and Google Scholar and contacted authors where necessary. We searched all terms related to homosexual, lesbian and bisexual people and all terms related to mental disorders, suicide, and deliberate self harm. We included papers on population based studies which contained concurrent heterosexual comparison groups and valid definition of sexual orientation and mental health outcomes. RESULTS: Of 13706 papers identified, 476 were initially selected and 28 (25 studies) met inclusion criteria. Only one study met all our four quality criteria and seven met three of these criteria. Data was extracted on 214,344 heterosexual and 11,971 non heterosexual people. Meta-analyses revealed a two fold excess in suicide attempts in lesbian, gay and bisexual people [pooled risk ratio for lifetime risk 2.47 (CI 1.87, 3.28)]. The risk for depression and anxiety disorders (over a period of 12 months or a lifetime) on meta-analyses were at least 1.5 times higher in lesbian, gay and bisexual people (RR range 1.54-2.58) and alcohol and other substance dependence over 12 months was also 1.5 times higher (RR range 1.51-4.00). Results were similar in both sexes but meta analyses revealed that lesbian and bisexual women were particularly at risk of substance dependence (alcohol 12 months: RR 4.00, CI 2.85, 5.61; drug dependence: RR 3.50, CI 1.87, 6.53; any substance use disorder RR 3.42, CI 1.97-5.92), while lifetime prevalence of suicide attempt was especially high in gay and bisexual men (RR 4.28, CI 2.32, 7.88). CONCLUSION: LGB people are at higher risk of mental disorder, suicidal ideation, substance misuse, and deliberate self harm than heterosexual people.

Can primary care identify an 'at risk' group in the older population.

The promotion of health and independence for older people through preventative strategies is rising up the public health agenda in many countries and has been made a government policy objective in the UK. Despite forty years of experimentation, community nursing and general practice involvement in this field has been characterized by a lack of evidence to support broad screening and surveillance programmes and a failure to reach consensus on the most effective approaches to health promotion in later life. One initiative brought together community nursing, general practice and the voluntary social welfare sector in an inner urban setting to proactively identify and address unmet need and promote health through short term case management in an older population. This paper reports on the ability of the primary care teams to identify 'at risk' groups in the older population, which can then be targeted for comprehensive assessment.

The development of a short instrument to identify common unmet needs in older people in general practice.

BACKGROUND: No structured needs assessment tool exists that is appropriate for older people and also suitable for use in routine consultations in general practice. AIMS: To engage older people in the development of a brief, valid, practical, and acceptable instrument to help identify common unmet needs suitable for use in routine clinical practice in primary care. DESIGN OF STUDY: User involvement in a multi-stages approach to heuristic development. SETTING: General practices, voluntary groups, and community organisations in north and central London. METHOD: Subjects included patients aged 65 years and over in purposively selected practices, voluntary organisations for older people in the same localities, community organisations involving older people, general practitioners and community nurses. Data were collected through mixed methodology interviews using a structured assessment tool (Camberwell Assessment of Need for the Elderly), a postal questionnaire, and focus groups. Synthesis and interpretation of results was done through a consensus conference followed by a Delphi process involving primary care professionals. RESULTS: Five domains of unmet need were identified as priority areas by all three data collection methods, the consensus conference, and the Delphi process: senses (vision and hearing), physical ability (mobility and falls), incontinence, cognition, and emotional distress (depression and anxiety) (SPICE). CONCLUSIONS: Public involvement in the design of clinical tools allowed the development of a brief assessment instrument that could potentially identify common, important, and tractable unmet needs in older people.

Older people's services. A picture of health.

A scheme offering joint health and social care assessments to people aged over 75 in inner London identified more than a quarter in need of services. The older people were accessed via general practice, but this proved an inefficient way of identifying the target population. In some practices, almost half of those contacted were no longer at the same address. The assessments, conducted by a community nurse and social welfare officer, often involved two visits. The mobility of the elderly population needs to be taken into account when planning joint assessments. Organisations involved had different aspirations for the scheme and management proved problematic.
