RESUMO

Substantial health benefits can be derived from walking at a moderate intensity cadence. To help regulate this cadence, three distinct aids exist 1) self-perception; 2) cadence prescription; 3) auditory cues. This study aimed to compare the effectiveness and explore perceptions of these aids to promote moderate intensity walking and effects on affective states, thereby addressing an important research gap. Individualised moderate relative intensity waking cadence was determined for participants (n = 23, Mage = 26.35, SD = 10.11). A convergent mixed-methods design was employed. A within-persons repeated measures design was used to explore the effectiveness of three aids (general guidelines, cadence prescription, and music) on promoting moderate intensity physical activity and positive affective states. Perceptions of these aids were elicited through qualitative interviews and thematic content analysis. Main effects for condition on relative physical activity intensity (η2 = .72) and positive affect (η2 = .25) were observed. Music evoked significantly higher relative physical activity intensity than other conditions (p values < .01), and higher positive affect compared to the general guidelines condition (p = .038). A significantly greater proportion of participants achieved moderate relative intensity physical activity during the music compared to general guidelines condition (p = .03). Congruently, qualitative findings suggested that participants predominantly perceived music as most effective for promoting a moderate intensity cadence and positive affect. However, individual variability existed in ability to utilise this aid. Implications of the findings for practitioners seeking to promote a moderate intensity cadence and positive affect during walking are discussed.

RESUMO

Menopause is a natural developmental phase that all women go through from their early forties to mid-fifties, marking the transition from the reproductive to the non-reproductive years. This is characterised as the permanent cessation of menses due to progressive ovarian failure. Each woman's experience of the menopause is unique. Biopsychosocial changes occur during this time with some symptoms affecting up to 80 % of women and lasting for 4-5 years from the peri- to post-menopause. Reduced oestrogen may predispose some women to health issues following menopause, such as heart disease, diabetes, stroke and cognitive decline. It is vital to understand how to promote health and well-being to reduce the risk of developing chronic conditions in later life. Increased symptoms and concerns about health during the menopausal transition can be cues to action for some women to actively maintain their health. Menopause represents a window of opportunity to promote health, and to support women to make healthier lifestyle choices, part of the National Institute for Clinical Excellence guidelines for menopause management. Identifying appropriate strategies to change behaviour is less clear. Theories of behaviour change can provide frameworks to gain more insight into the facilitators and barriers to behaviour and can inform the researcher on what needs to change. This information can be used to inform the design, content, implementation and evaluation of a lifestyle intervention. This review paper will explore the impact of menopause on health and well-being generally, and the benefits of designing more effective theory-driven behaviour change interventions for menopause.

RESUMO

AIMS: The aim of this study is to analyse the demographics, diagnosis, nodal yield, metastatic rates and outcomes of patients undergoing neck dissections within the Waikato Hospital Oral and Maxillofacial Surgery (OMS) Department. METHODS: All patients that underwent neck dissections under the care of OMS at Waikato Hospital between January 2016 and December 2021 were included. Data on patient demographics, diagnosis, surgery details, nodal yields, histological results and clinical outcome were collected retrospectively for analysis. RESULTS: One hundred and five patients and 123 neck dissections were included in the final analysis. The median age was 65 years of age. The average nodal yield from a selective neck dissection of levels I-III was 20.1 and I-IV was 25.4. There was no metastatic nodal disease in level IIb, and only 2 neck dissections with nodal disease in level IV. Complications were mostly associated with free flap reconstruction rather than the neck dissection alone. CONCLUSIONS: The demographics and outcomes of the study cohort are consistent with both the current population and previously published head and neck data. The OMS unit at Waikato Hospital recommends omission of levels IIb and IV in neck dissections for cN0 cases if deemed oncologically safe to do so.

RESUMO

AIMS: This study compared those living with and without an intestinal stoma in relation to physical and psychological health, stress and coping, quality of life and resilience. Also, identifying factors that could be used to promote better self-care in stoma patients in the future. DESIGN: A cross-sectional and comparative study design was employed. METHODS: Participants were recruited via email and social media (Facebook and Twitter) between August 2018 and March 2019, to complete an online survey. The data were analysed using analysis of variance to examine group difference and a series of hierarchical linear regression analyses determining predictors of psychological well-being. RESULTS: Of 278 participants aged 18-68 years who completed the survey, 129 (46%) had a stoma and reported significantly poorer physical health. Approximately one-fifth experienced problems with stoma management. Psychological well-being was mediated by the duration of living with a stoma (under 3 years) and frequency of leaks (weekly and monthly).

RESUMO

Objectives: Identify prevalence rates and attitudes towards e-cigarette use among parents to inform prevention strategies designed to reduce uptake in young people. Study design: A mixed methods sequential study guided by the Theory of Planned Behaviour. Methods: This research involved two phases. Phase one was an elicitation study using focus groups, interviews and open-ended questionnaires (N = 17) to elicit parental behavioural, normative, and control beliefs around e-cigarette use. Findings from phase 1 were used to inform a questionnaire administered to a sample of 612 parents in phase 2. The aim of phase 2 was to identify and explain factors that influence parental attitudes and motivations towards e-cigarette use. Parents were recruited through post-primary schools and were sent a link to an online survey. Results: Approximately 19% of parents had tried an e-cigarette, with 9% reporting current use. Sociodemographic variables, TPB constructs and knowledge of e-cigarettes, accounted for 43% and 60% of ever use and intention to use an e-cigarette, respectively. Intention, gender, age and free school meal entitlement were associated with ever use. Intention to use an e-cigarette was related to lower educational level, current smoking of traditional cigarettes, more positive attitudes, greater social pressure, having greater control over use and knowledge. Conclusions: Prevention strategies designed to reduce uptake in young people should raise awareness of the health risks of e-cigarette use, legislation and regulations and highlight the role parents play in encouraging young people to abstain from using an e-cigarette.

RESUMO

The Oral and Maxillofacial Surgery (OMS) Department at Waikato District Health Board (WDHB) is the only current OMS unit within New Zealand to reconstruct oral cavity defects with microvascular free flaps. The primary objective of the study was to retrospectively analyse the demographics, outcomes and complications of free flap surgery patients at WDHB.An OMS reconstruction database was developed and data collected retrospectively. 75 free flaps were performed on 74 patients between 2012 and 2020. There were 34 females and 40 males, with a mean and median age of 62 and 64 respectively. The tongue was the most common site of resection, and squamous cell carcinoma was the most frequent diagnosis. The radial forearm free flap was used most often followed by the fibula and anterolateral thigh flaps. The Clavien-Dindo classification was used to classify complications, with 10 patients having "major" complications and 34 patients having "minor" complications. Flap success rate was 98.7%, which meets internationally accepted standards of care.

RESUMO

PURPOSE: This literature review examines the provision of an education on pharmacologically active complementary and alternative medicines (CAMs), to people with cancer, their carers and oncology health professionals. METHODS: A search of the published literature between 2000 and 2020, in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, was conducted. The search retrieved 1121 studies, 1080 were excluded based on their title or abstract and 26 articles were excluded based on their text. One article was retrieved from the reference lists of the included articles and in total fifteen studies met the inclusion criteria. This review utilised Medical Education Research Quality Instrument (MERSQI) to evaluate the quality of the included studies. Four key outcomes were utilised for analysis and recommendations for future education and/or research were generated. The recommendations were graded according to the Strength of Recommendation Taxonomy (SORT). RESULTS: This review consistently found that people with cancer, their carers and oncology health professionals derived benefit from a pharmacologically active CAM education and recommends that this population receives one. Conversely, the review found many education formats utilised and no consensus on the most successful methods. CONCLUSION: Future research should examine who a CAM education should be delivered to, what type of delivery platform is most accessible and useful, and the features of the education that most increase CAM knowledge. The popularity of CAMs amongst people with cancer and the potential dangers associated with their use necessitates further research into how best to communicate CAMs to this population.

RESUMO

Evidence suggests that being physically active may improve quality of life through the menopausal transition. This study is one of the first to investigate how meeting the UK Physical Activity Guidelines (PAG) impacted quality of life, stress, coping and menopausal symptoms in UK midlife women, aged 45-55 years, during the unfolding Covid pandemic (Phase 1 quantitative, n=164). The study also explored their motivation to undertake regular physical activity during Covid lockdown (Phase 2 qualitative, n=4). An explanatory sequential mixed-methods design was used to collate quantitative (survey) and qualitative (focus group) data. Participants who met PAG experienced fewer depressive symptoms and less perceived stress, and had better physical and mental health and quality of life than women who did not. This was supported by focus group discussions reporting lack of facilities, time constraints, reduced social support and existing health complaints as barriers to physical activity. Factors motivating women to exercise during Covid lockdown were benefits for physical and mental health, and support from friends (Qualitative). Women are postmenopausal for one-third of their lives, and health interventions need to promote positive healthy ageing around menopause. Menopausal changes could be used by clinicians as cues to action to promote female health and well-being. Clinicians should be promoting the health benefits of exercise and making women aware of the importance of aiming to meet the PAG for optimal health benefits. Women should be encouraged to increase their levels of physical activity by making plans and setting goals and gaining support by exercising with friends or family, as a way to better control menopausal symptoms.

RESUMO

BACKGROUND: The aim of the study was to identify and compare components of the COM-B (capability, opportunity, motivation and behaviour) model, that influences behaviour to modify dietary patterns in 40-55-year olds living in Northern Ireland (NI) and Italy, in order to reduce the risk of cognitive decline in later life. METHODS: This was a qualitative study examining factors influencing Mediterranean-DASH (Dietary Approaches to Stop Hypertension) Intervention for Neurodegenerative Delay (MIND) diet behaviour. This study further elaborated the COM-B components into the 14 domains of the Theoretical Domains Framework to further understand behaviour. Twenty-five Northern Irish and Italian participants were recruited onto the study, to take part in either a focus group or an interview. Participants were both male and female aged between 40 and 55 years. RESULTS: Thematic analysis revealed that the main barriers to the uptake of the MIND diet were; time, work environment (opportunity), taste preference and convenience (motivation). Culture (motivation), seasonal foods and lack of family support (opportunity) to be a barrier to the Italian sample only. The main facilitators reported were; improved health, memory, planning and organisation (motivation) and access to good quality food (opportunity). Cooking skills, knowledge (capability) and heathy work lunch (opportunity) reported as a facilitator to the Italian sample only. CONCLUSIONS: Cross-cultural differences in relation to psychosocial barriers and facilitators were found in both samples. More barriers than facilitators towards uptake of the MIND diet were found. There is a need for interventions that increase capability, opportunity, and motivation to aid behaviour change. The findings from this study will be used to design a behaviour change intervention using the subsequent steps from the Behaviour Change Wheel.

RESUMO

Complementary and alternative medicine (CAM) usage amongst cancer patients is high globally and in Australia. CAM use in cancer care has the ability to increase chemotherapy toxicity or cause sub-therapy due to altered metabolism as well as increase a patient's bleeding risk. Furthering these risks, people with cancer are largely obtaining their CAM use information from non-evidence-based sources. This study aimed to determine whether the implementation of a CAM education influenced decision-making with regard to CAM usage amongst cancer patients. Twenty people with cancer were recruited for participation in this study. The aims of this study were achieved by surveying patients via questionnaire, both prior to and following receiving an evidence-based CAM education, in either or both written or audiovisual format. This exploratory study found, consistent with the literature, that the majority of participants were obtaining their CAM use information from non-evidenced-based sources. Additionally, it found that the participants wanted more CAM use information and that they demonstrated some altered decision-making after receiving evidenced-based information. On the post-educational questionnaire, the number of participants that stated that they would use CAMs decreased by almost 14%, and some participants made CAM use decisions in accordance with the information provided in the resources. Furthermore, a small increase in CAM knowledge was demonstrated, and it was reported that the resource had prompted them to look further into CAM information. Lastly, the participants in this study found the resource to be mostly useful and helpful and preferred the animated video to the written information.

RESUMO

OBJECTIVE: The aim of the study was to identify components of the COM-B (capability, opportunity, motivation and behaviour) model that influences behaviour to modify dietary patterns in 40-55-year-olds living in the UK, in order to influence the risk of cognitive decline in later life. DESIGN: This is a qualitative study using the COM-B model and theoretical domains framework (TDF) to explore beliefs to adopting the Mediterranean-DASH Intervention for Neurodegenerative delay (MIND) diet. SETTING: Northern Ireland. PARTICIPANTS: Twenty-five participants were recruited onto the study to take part in either a focus group or an interview. Participants were men and women aged between 40 and 55 years. Participants were recruited via email, Facebook and face to face. RESULTS: Content analysis revealed that the main perceived barriers to the adoption of the MIND diet were time, work environment, taste preference and convenience. The main perceived facilitators reported were improved health, memory, planning and organisation, and access to good quality food. CONCLUSIONS: This study provides insight into the personal, social and environmental factors that participants report as barriers and facilitators to the adoption of the MIND diet among middle-aged adults living in the UK. More barriers to healthy dietary change were found than facilitators. Future interventions that increase capability, opportunity and motivation may be beneficial. The results from this study will be used to design a behaviour change intervention using the subsequent steps from the Behaviour Change Wheel.

RESUMO

BACKGROUND: The term 'whole dietary pattern' can be defined as the quantity, frequency, variety and combination of different foods and drinks typically consumed and a growing body of research supports the role of whole dietary patterns in influencing the risk of non-communicable diseases. For example, the 'Mediterranean diet', which compared to the typical Western diet is rich in fruits and vegetables, whole grains, and oily fish, is associated with reduced risk of cardiovascular disease and cancer. Social Cognition Models provide a basis for understanding the determinants of behaviour and are made up of behavioural constructs that interventions target to change dietary behaviour. The aim of this systematic review was to provide a comprehensive assessment of the effectiveness and use of psychological theory in dietary interventions that promote a whole dietary pattern. METHODS: We undertook a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis to synthesize quantitative research studies found in Embase, Medline, PsycInfo, CINAHL and Web of Science. The studies included were randomised and non-randomised trials published in English, involving the implementation of a whole dietary pattern using a Social Cognition Model to facilitate this. Two independent reviewers searched the articles and extracted data from the articles. The quality of the articles was evaluated using Black and Down quality checklist and Theory Coding Scheme. RESULTS: Nine intervention studies met the criteria for inclusion. Data from studies reporting on individual food group scores indicated that dietary scores improved for at least one food group. Overall, studies reported a moderate application of the theory coding scheme, with poor reporting on fidelity. CONCLUSION: To our knowledge, this is the first review to investigate psychological theory driven interventions to promote whole dietary patterns. This review found mixed results for the effectiveness of using psychological theory to promote whole dietary pattern consumption. However, the studies in this review scored mostly moderate on the theory coding scheme suggesting studies are not rigorously applying theory to intervention design. Few studies reported high on treatment fidelity, therefore, translation of research interventions into practice may further impact on effectiveness of intervention. Further research is needed to identify which behaviour change theory and techniques are most salient in dietary interventions.

RESUMO

PURPOSE: Cognitive decline is commonly reported during the menopausal transition, with memory and attention being particularly affected. The aim of this study was to investigate the effects of a commercially available soy drink on cognitive function and menopausal symptoms in post-menopausal women. METHODS: 101 post-menopausal women, aged 44-63 years, were randomly assigned to consume a volume of soy drink providing a low (10 mg/day; control group), medium (35 mg/day), or high (60 mg/day) dose of isoflavones for 12 weeks. Cognitive function (spatial working memory, spatial span, pattern recognition memory, 5-choice reaction time, and match to sample visual search) was assessed using CANTAB pre- and post-the 12 week intervention. Menopausal symptoms were assessed using Greene's Climacteric Scale. RESULTS: No significant differences were observed between the groups for any of the cognitive function outcomes measured. Soy drink consumption had no effect on menopausal symptoms overall; however, when women were stratified according to the severity of vasomotor symptoms (VMS) at baseline, women with more severe symptoms at baseline in the medium group had a significant reduction (P = 0.001) in VMS post-intervention (mean change from baseline score: - 2.15 ± 1.73) in comparison to those with less severe VMS (mean change from baseline score: 0.06 ± 1.21). CONCLUSIONS: Soy drink consumption had no effect on cognitive function in post-menopausal women. Consumption of ~ 350 ml/day (35 mg IFs) for 12 weeks significantly reduced VMS in those with more severe symptoms at baseline. This finding is clinically relevant as soy drinks may provide an alternative, natural, treatment for alleviating VMS, highly prevalent among western women.

RESUMO

This study sought to identify which of the many facilitators and barriers to physical activity (PA) and walking are most significant to changing midlife women's exercise behaviour, with a view to informing future interventions. A cross-sectional survey explored associations of PA and sedentary time with self-reported health value, health locus of control (HLOC) and physical and mental health. Open-ended questions were included to elicit barriers and facilitators to walking. A sample of 295 women, aged 35-55, was recruited via women's groups, social media, online forums, and posters in doctors' surgeries, and completed the survey online. Quantitative data were analysed using descriptive statistics, t-test, analysis of variance and regression analyses. The low activity levels reported underline the urgency of developing interventions for this population. Results suggest that the key factors associated with higher activity levels are having a more internal HLOC, better mental health and placing greater value on health. While health cognitions may therefore be one important factor to target, these must be tackled in the context of women's other barriers to and facilitators of exercise. Thematic analysis of the open-ended questions revealed that the key barrier to walking was women's busy lives and their many competing priorities and that the most important facilitators were mental health and social connection. Overall, results suggest that, rather than emphasizing physical health and activity targets, practitioners should seek to make walking more relevant to women by emphasizing mental wellbeing and self-care, and more enjoyable by focusing on social and family-based walking interventions.

RESUMO

OBJECTIVE: Dietary soy may improve menopausal symptoms, and subsequently mediate mood. This novel study examines various doses of dietary soy drink on everyday mood stability and variability in postmenopausal women. METHODS: Community-dwelling women (n = 101), within 7 years postmenopause, consumed daily either a low (10 mg, n = 35), medium (35 mg, n = 37), or high (60 mg, n = 29) dose of isoflavones, for 12 weeks. Menopausal symptoms and repeated measures of everyday mood (positive [PA] and negative [NA] affect) (assessed at four time points per day for 4 consecutive days, using The Positive and Negative Affect Schedule) were completed at baseline and follow-up. RESULTS: The dietary soy intervention had no effect on everyday mood stability (for PA [F{2,70} = 0.95, P = 0.390] and NA [F{2,70} = 0.72, P = 0.489]) or variability (for PA [F{2,70} = 0.21, P = 0.807] and for NA [F{2,70} = 0.15, P = 0.864]), or on menopausal symptoms (for vasomotor [F{2,89} = 2.83, P = 0.064], psychological [F{2,88} = 0.63, P = 0.535], somatic [F{2,89} = 0.32, P = 0.729], and total menopausal symptoms [F{2,86} = 0.79, P = 0.458]). There were between-group differences with the medium dose reporting higher PA (low, mean 24.2, SD 6; and medium, mean 29.7, SD 6) and the low dose reporting higher NA (P = 0. 048) (low, mean 11.6, SD 2; and high, mean 10.6, SD 1) in mood scores. Psychological (baseline M = 18 and follow-up M = 16.5) and vasomotor (baseline M = 4.2 and follow-up M = 3.6) scores declined from baseline to follow-up for the overall sample. CONCLUSIONS: Soy isoflavones had no effect on mood at any of the doses tested. Future research should focus on the menopause transition from peri to postmenopause as there may be a window of vulnerability, with fluctuating hormones and increased symptoms which may affect mood.

RESUMO

BACKGROUND: Zinc is an essential component for all living organisms, representing the second most abundant trace element, after iron. This element is widely distributed in the tissues of a human body where it is involved in normal growth, reproduction and several biological functions including immunity, energy metabolism and antioxidant processes. Because of its essential role, zinc levels in the human body must remain constant, independently of dietary intake fluctuations. The homeostasis of zinc is a well-regulated cellular process and has been reported to be chiefly mediated by the expression and activity of zinc-binding proteins such as metallothioneins and zinc transporters. Genes encoding for these proteins are subjected to genetic variants. METHODS: We performed a multi-database electronic search to provide an overview on the relationship between specific polymorphisms (SNP) of genes encoding for metallothioneins and zinc transporters and their relationship with zinc status, immune function and some non-communicable diseases. RESULTS: A number of SNP are implicated in a range of metabolic disease. Some SNP may affect the impact of zinc supplementation on immune function, diabetes, and obesity. CONCLUSION: New studies are needed to clarify the interaction between individual genetic profile and zinc status. Moreover, there is a need for a better interaction between the scientific bodies and health professionals to allow better dietary and behavioural recommendations to promote human health, with particular concern to elderly people.

RESUMO

BACKGROUND: Levels of physical activity decline with age. Some of the most disadvantaged individuals in society, such as those from lower socio-economic position, are also the most inactive. Increasing physical activity levels, particularly among those most inactive, is a public health priority. Peer-led physical activity interventions may offer a model to increase physical activity in the older adult population. This study aims to test the feasibility of a peer-led, multicomponent physical activity intervention in socio-economically disadvantaged community dwelling older adults. METHODS: The Medical Research Council framework for developing and evaluating complex interventions will be used to design and test the feasibility of a randomised controlled trial (RCT) of a multicomponent peer-led physical activity intervention. Data will be collected at baseline, immediately after the intervention (12 weeks) and 6 months after baseline measures. The pilot RCT will provide information on recruitment of peer mentors and participants and attrition rates, intervention fidelity, and data on the variability of the primary outcome (minutes of moderate to vigorous physical activity measured with an accelerometer). The pilot trail will also assess the acceptability of the intervention and identify potential resources needed to undertake a definitive study. Data analyses will be descriptive and include an evaluation of eligibility, recruitment, and retention rates. The findings will be used to estimate the sample size required for a definitive trial. A detailed process evaluation using qualitative and quantitative methods will be conducted with a variety of stakeholders to identify areas of success and necessary improvements. DISCUSSION: This paper describes the protocol for the 'Walk with Me' pilot RCT which will provide the information necessary to inform the design and delivery of a fully powered trial should the Walk with Me intervention prove feasible.

RESUMO

Although physical activity guidelines recommend muscle-strengthening activities (MSA), public health initiatives tend to focus on increasing aerobic activity and fail to mention MSA. This study sought to identify the issues influencing pre-, peri- and post-menopausal women's intentions to perform MSA with a view to informing future interventions for these populations. Mixed methods guided by the Theory of Planned Behaviour (TPB) were used to explore factors that influence women's intentions to perform MSA. In stage one, 34 women participated in either a focus group or interview. Discussions were transcribed verbatim and analysed based on menopausal status using a deductive approach. In stage two, 186 women (M = 47 years, SD = 9) completed a questionnaire to assess participant demographics, levels of MSA, affective and instrumental attitudes, injunctive and descriptive norms, self-efficacy and perceived behavioural control. Quantitative data were analysed using descriptive statistics, bivariate correlations, regression analyses and analysis of variances. Behavioural beliefs were: improved muscular health; psychological benefits; improved body shape. Normative beliefs were: health professionals; family members; work colleagues. Control beliefs were: equipment; motivation; time constraints; knowledge; physical capability; fear of judgement. However, these beliefs were not well established. Self-efficacy was the strongest predictor of intentions (spc2 = 0.11) followed by affective attitudes (spc2 = 0.09), with no significant differences on TPB variables between groups. If rising rates of musculoskeletal conditions in women are to be prevented, there is an urgent need to increase women's knowledge of recommended levels of muscle strengthening, with a view to promoting positive attitudes and enhancing women's sense of self-efficacy across all menopausal phases.

RESUMO

OBJECTIVES: This study explored the mechanisms of physical activity (PA) compensation among older adults who recently reduced their non-exercise physical activity (NEPA) in response to a structured PA intervention. DESIGN: A post-trial, retrospective qualitative process evaluation using interviews was employed. METHODS: Levels of PA compensation were determined by comparing NEPA prior to and during the final week of a 4-week structured PA intervention. Those who reduced their NEPA by 10% or greater were considered as compensators. Interviews were conducted with older adult compensators (mean age = 58.56 ± 3.88 years; n = 9), employing thematic analysis to identify potential mechanisms of PA compensation. RESULTS: The findings suggest that the majority of participants were unaware that they had compensated in their PA, suggesting that this may be a non-volitional process. Most participants perceived PA compensation to hold negative implications for health and well-being. Physiological processes of fatigue and delayed onset of muscle soreness were cited as the principal cause of PA compensation, whereas psychological processes including a drive to be inactive, fear of overexertion, deficient motivation, and perceived time constraints were cited to a lesser extent. CONCLUSION: A range of physiological and psychological compensatory barriers were identified. Implications of and methods to overcome these compensatory barriers are discussed. Statement of contribution What is already known on this subject? Physical activity compensation holds negative implications for physical activity promotion and health. Older adults are an age group more likely to compensate in their physical activity levels. What does this study add? Physical activity compensation may be a result of a range of physiological and psychological processes including fatigue and delayed onset of muscle soreness, compensatory health beliefs, fear of overexertion, deficient motivation, and perceived time constraints. Most older adult compensators may be unaware they are compensating and, however, agree that physical activity compensation has negative implications for health and well-being.

RESUMO

BACKGROUND: the transition to motherhood can be stressful, especially for first time mothers. Recent research has shown that yoga can be effective for enhancing psychological well-being. OBJECTIVES: the purpose of this study was to establish if a postpartum Dru yoga intervention improves psychological well-being in first time mothers. DESIGN: a randomised controlled study was conducted. SETTING AND PARTICIPANTS: first time mothers were recruited from a Sure Start Community Centre and included in the study if they had a baby aged between 6 weeks to one-year-old. Exclusion criteria were the presence of sciatica, bulging discs, heart disease or whiplash and if they already practiced yoga. METHODS: participants were randomised into a Dru yoga group (n=16) who received a one-hour Dru yoga session each week for 4 weeks and a 20-minute DVD for practice at home. The control group (n=16) who did not receive an intervention. Baseline and follow up measures of perceived stress, mood and coping were assessed in each group. RESULTS: a repeated measures factorial Analysis of Variance showed that in comparison to the control group, the Dru yoga intervention group had improved psychological well-being as indicated by reductions in stress, negative affect, and dysfunctional coping and increases in problem focused coping at follow up (P<0.05). CONCLUSION: the current study shows that Dru yoga is beneficial for the psychological well-being of first time mothers. Further research is needed using large scale replication studies with a longer follow up period and including multiparous women. This study extends the support for yoga with postpartum mothers.
