The experiences of individuals who have had gestational diabetes: A qualitative exploration.

AIM: To qualitatively explore the experiences of individuals with Gestational Diabetes Mellitus (GDM) in Australia, and to recognise opportunities for leveraging digital health to enhance the support of GDM management. METHOD: A cross sectional online survey assessed the experiences of individuals with GDM, the healthcare system and their digital health usage. Respondents (recruited via a national diabetes registry or social media) were adults receiving GDM care within Australia in the last 5 years, who responded to any of three open-ended questions (n = 815) exploring positive, negative and other GDM experiences. Thematic analysis was utilised, and themes were mapped to the socio-ecological systems framework. RESULTS: At a system level, themes related to (1) accessibility of care including the value of digital health and the inflexible or inconsistent perception of the (2) implementation of guidelines. At an interpersonal level, themes covered the need for adequate (3) health information provision, and (4) supportive care, as well as highlighting (5) experiences of stigma including a desire for greater awareness of GDM. Individual-level themes included: (6) differential barriers to accessing care; (7) negative emotional burden; (8) internalisation of stigma; (9) dietary freedom and social impact and (10) opportunity for change derived from having GDM. CONCLUSION: Findings suggest a demand for more supportive, person-centred GDM care, improved information provision and individualised implementation of clinical guidelines. Such mechanisms may support reduced barriers to accessing care or negative psychosocial impacts of GDM. Though not central to the identified experiences, digital health tools may help address the need for optimised GDM care.

Effectiveness of a web- and mobile phone-based intervention to promote physical activity and healthy eating in middle-aged males: randomized controlled trial of the ManUp study.

BACKGROUND: The high number of adult males engaging in low levels of physical activity and poor dietary practices, and the health risks posed by these behaviors, necessitate broad-reaching intervention strategies. Information technology (IT)-based (Web and mobile phone) interventions can be accessed by large numbers of people, yet there are few reported IT-based interventions targeting males' physical activity and dietary practices. OBJECTIVE: This study examines the effectiveness of a 9-month IT-based intervention (ManUp) to improve the physical activity, dietary behaviors, and health literacy in middle-aged males compared to a print-based intervention. METHODS: Participants, recruited offline (eg, newspaper ads), were randomized into either an IT-based or print-based intervention arm on a 2:1 basis in favor of the fully automated IT-based arm. Participants were adult males aged 35-54 years living in 2 regional cities in Queensland, Australia, who could access the Internet, owned a mobile phone, and were able to increase their activity level. The intervention, ManUp, was based on social cognitive and self-regulation theories and specifically designed to target males. Educational materials were provided and self-monitoring of physical activity and nutrition behaviors was promoted. Intervention content was the same in both intervention arms; only the delivery mode differed. Content could be accessed throughout the 9-month study period. Participants' physical activity, dietary behaviors, and health literacy were measured using online surveys at baseline, 3 months, and 9 months. RESULTS: A total of 301 participants completed baseline assessments, 205 in the IT-based arm and 96 in the print-based arm. A total of 124 participants completed all 3 assessments. There were no significant between-group differences in physical activity and dietary behaviors (P≥.05). Participants reported an increased number of minutes and sessions of physical activity at 3 months (exp(ß)=1.45, 95% CI 1.09-1.95; exp(ß)=1.61, 95% CI 1.17-2.22) and 9 months (exp(ß)=1.55, 95% CI 1.14-2.10; exp(ß)=1.51, 95% CI 1.15-2.00). Overall dietary behaviors improved at 3 months (exp(ß)=1.07, 95% CI 1.03-1.11) and 9 months (exp(ß)=1.10, 95% CI 1.05-1.13). The proportion of participants in both groups eating higher-fiber bread and low-fat milk increased at 3 months (exp(ß)=2.25, 95% CI 1.29-3.92; exp(ß)=1.65, 95% CI 1.07-2.55). Participants in the IT-based arm were less likely to report that 30 minutes of physical activity per day improves health (exp(ß)=0.48, 95% CI 0.26-0.90) and more likely to report that vigorous intensity physical activity 3 times per week is essential (exp(ß)=1.70, 95% CI 1.02-2.82). The average number of log-ins to the IT platform at 3 and 9 months was 6.99 (SE 0.86) and 9.22 (SE 1.47), respectively. The average number of self-monitoring entries at 3 and 9 months was 16.69 (SE 2.38) and 22.51 (SE 3.79), respectively. CONCLUSIONS: The ManUp intervention was effective in improving physical activity and dietary behaviors in middle-aged males with no significant differences between IT- and print-based delivery modes.

Food, nutrition and the dining experience in aged care settings: Findings of a nationwide survey.

OBJECTIVE: Previous research on food, nutrition and dining practices in Australian residential aged care (RAC) homes has been based on a limited sample of single-home or multiple-home providers, but a nationwide study has not been conducted. The aim of this study was to provide a preliminary overview of current food, nutrition and dining practices across Australian RAC facilities using a nationwide survey. METHODS: A survey was distributed to Australian RAC homes in August-September 2020, as part of the National Congress on Food, Nutrition and the Dining Experience in Aged Care (February 2021). The survey, administered via an online portal, consisted of 38 semistructured questions including yes/no or multiple-choice responses, free text, frequency scales and number entry. Six key topics were explored, including 'food service system and environment', 'catering style', 'menu planning and evaluation', 'nutrition planning and requirements', 'nutrition-related screening and assessment' and 'training and additional information', which were informed by the Australian Government Department of Health and reflected the interests of the Congress. RESULTS: The final sample included 292 respondents (204 individual homes and 88 multiple-home proprietors) representing 1152 homes and 125,393 residents, encompassing approximately 43% of RAC homes (of a possible 2671) and 57% of residents (of a possible 219,965) in Australia. Survey respondents representing RAC homes included service managers, catering managers, Chief Executive Officers, cooks, chefs, dietitians or staff from other roles within homes. A number of potential areas of need were identified, included increasing the autonomy of residents to select the foods they desire, increasing the variety and choice (including timing) of meals, enhancing the dining environments in homes to stimulate food intake and increasing staff training and the number of trained chefs in homes, so that meals are prepared which address diverse nutritional needs of residents. CONCLUSIONS: This study provides insight into the food service and mealtime practices of over a third of Australian RAC homes. The findings of this survey may help to identify key targets for intervention to improve the food, nutrition and quality of life of aged care residents.

A review of the nature and effectiveness of nutrition interventions in adult males--a guide for intervention strategies.

BACKGROUND: Energy excess, low fruit and vegetable intake and other suboptimal dietary habits contribute to an increased poor health and the burden of disease in males. However the best way to engage males into nutrition programs remains unclear. This review provides a critical evaluation of the nature and effectiveness of nutrition interventions that target the adult male population. METHODS: A search for full-text publications was conducted using The Cochrane Library; Web of Science; SCOPUS; MEDLINE and CINAHL. Studies were included if 1) published from January 1990 to August 2011 and 2) male only studies (≥18 years) or 3) where males contributed to >90% of the active cohort. A study must have described, (i) a significant change (p<0.05) over time in an objective measure of body weight, expressed in kilograms (kg) OR Body Mass Index (BMI) OR (ii) at least one significant change (p<0.05) in a dietary intake measure to qualify as effective. To identify emerging patterns within the research a descriptive process was used. RESULTS: Nine studies were included. Sample sizes ranged from 53 to 5042 male participants, with study durations ranging from 12 weeks to 24 months. Overlap was seen with eight of the nine studies including a weight management component whilst six studies focused on achieving changes in dietary intake patterns relating to modifications of fruit, vegetable, dairy and total fat intakes and three studies primarily focused on achieving weight loss through caloric restriction. Intervention effectiveness was identified for seven of the nine studies. Five studies reported significant positive changes in weight (kg) and/or BMI (kg/m2) changes (p≤0.05). Four studies had effective interventions (p<0.05) targeting determinants of dietary intake and dietary behaviours and/or nutritional intake.Intervention features, which appeared to be associated with better outcomes, include the delivery of quantitative information on diet and the use of self-monitoring and tailored feedback. CONCLUSION: Uncertainty remains as to the features of successful nutrition interventions for males due to limited details provided for nutrition intervention protocols, variability in mode of delivery and comparisons between delivery modes as well as content of information provided to participants between studies. This review offers knowledge to guide researchers in making informed decisions on how to best utilise resources in interventions to engage adult males while highlighting the need for improved reporting of intervention protocols.

Use and Preferences of Health Apps among Women and Healthcare Professionals Regarding GDM Postpartum Care Related to Diet, Physical Activity, and Weight Management: A Cross-Sectional Survey.

Gestational Diabetes Mellitus (GDM) is a common medical complication of pregnancy, which is associated with increased risk of future diabetes. mHealth (mobile health, in this paper applications abbreviated to apps) can facilitate health modifications to decrease future risks. This study aims to understand mHealth app use and preferences among women with past GDM and healthcare professionals (HCP) in Australia. An explorative cross-sectional online survey was disseminated via social media, a national diabetes registry, and professional networks. Descriptive analyses were conducted on valid responses (women with prior GDM: n = 1475; HCP: n = 75). One third (33%) of women with prior GDM have used health apps, and a further 80% of non-app users were open to using a health app if recommended by their HCP. Over half (53%) of HCPs supported health information delivery via mHealth, although only 14% had recommended a health app to women post-GDM, and lack of knowledge about mHealth apps was common. Health app users reported that they preferred tracking features, while non-users desired credible health and dietary information and plans. Expanding mHealth app use could facilitate healthy behaviours, but endorsement by HCPs is important to women and is still currently lacking.

A primary care delivered, technology supported lifestyle program for Type 2 Diabetes Management: An evaluation of changes in metabolic health, feasibility, and acceptability - A pilot interventional study protocol.

Background: Type 2 Diabetes (T2D) is associated with significant health complications and socioeconomic costs. Previous research conducted through an outpatient research facility demonstrated use of a low carbohydrate (LC) diet and exercise plan delivered in the format of an education book combined with use of real-time continuous glucose monitoring (RT-CGM) is an effective self-management intervention to improve weight and blood glucose management in patients with T2D. Primary health care remains the central access point for patient management of T2D, but General Practitioners (GPs) lack access to effective evidenced-based, self-management programs that can be prescribed to improve patient outcomes. Methods: A single-arm, within-participant pilot intervention study will be conducted to evaluate the changes in metabolic health, acceptability and feasibility of a prescriptive LC diet and lifestyle program combined with RT-CGM (LC-RTC) delivered via GP practices. Forty adults with T2D will be recruited from GP practices and prescribed the LC-RTC intervention for 12 weeks. Outcomes will be assessed at baseline and 12-weeks post intervention. Changes in metabolic health will be assessed by changes in glycosylated hemoglobin (primary outcome), body weight, blood pressure, blood lipids, and medication usage. Post-intervention, participants will complete questionnaires and participate in focus groups to explore their experience of the LC-RTC program including acceptance, perceived benefits/barriers, limitations, financial feasibility, intervention drop-out rates, participant and GP engagement with the program (clinic attendance and contacts made to clinic for program support) and RT-CGM use and wear time acceptance. GPs and clinical staff involved will participate focus groups to evaluate the perceived value and feasibility of the LC-RTC program. Discussion: This trial will provide a powered evaluation of the changes in metabolic health, acceptability, and feasibility of the LC-RTC program for patients with T2D delivered via GP practices. Trial registration: ANZCTR: 12622000635763 (Website Link to full registration: ANZCTR - Registration). Registered 29th April 2022.

Effectiveness of a website and mobile phone based physical activity and nutrition intervention for middle-aged males: trial protocol and baseline findings of the ManUp Study.

BACKGROUND: Compared to females, males experience higher rates of chronic disease and mortality, yet few health promotion initiatives are specifically aimed at men. Therefore, the aim of the ManUp Study is to examine the effectiveness of an IT-based intervention to increase the physical activity and nutrition behaviour and literacy in middle-aged males (aged 35-54 years). METHOD/DESIGN: The study design was a two-arm randomised controlled trial, having an IT-based (applying website and mobile phones) and a print-based intervention arm, to deliver intervention materials and to promote self-monitoring of physical activity and nutrition behaviours. Participants (n = 317) were randomised on a 2:1 ratio in favour of the IT-based intervention arm. Both intervention arms completed assessments at baseline, 3, and 9 months. All participants completed self-report assessments of physical activity, sitting time, nutrition behaviours, physical activity and nutrition literacy, perceived health status and socio-demographic characteristics. A randomly selected sub-sample in the IT-based (n = 61) and print-based (n = 30) intervention arms completed objective measures of height, weight, waist circumference, and physical activity as measured by accelerometer (Actigraph GT3X). The average age of participants in the IT-based and print-based intervention arm was 44.2 and 43.8 years respectively. The majority of participants were employed in professional occupations (IT-based 57.6%, Print-based 54.2%) and were overweight or obese (IT-based 90.8%, Print-based 87.3%). At baseline a lower proportion of participants in the IT-based (70.2%) group agreed that 30 minutes of physical activity each day is enough to improve health compared to the print-based (82.3%) group (p = .026). The IT-based group consumed a significantly lower number of serves of red meat in the previous week, compared to the print-based group (p = .017). No other significant between-group differences were observed at baseline. DISCUSSION: The ManUp Study will examine the effectiveness of an IT-based approach to improve physical activity and nutrition behaviour and literacy. Study outcomes will provide much needed information on the efficacy of this approach in middle aged males, which is important due to the large proportions of males at risk, and the potential reach of IT-based interventions.

A Health Care Professional Delivered Low Carbohydrate Diet Program Reduces Body Weight, Haemoglobin A1c, Diabetes Medication Use and Cardiovascular Risk Markers-A Single-Arm Intervention Analysis.

This study examined the effectiveness of a health care professional delivered low-carbohydrate diet program (Diversa Health Program) aiming to improve obesity/type-2-diabetes management for people living in Australia. 511 adults (Age:57.1 ± 13.7 [SD] yrs) who participated between January 2017−August 2021 for ≥30 days with pre-post data collected for ≥1 key outcome variable (body weight and HbA1c) were included in the analysis. Average participation duration was 218 ± 207 days with 5.4 ± 3.9 reported consultation visits. Body weight reduced from 92.3 ± 23.0 to 86.3 ± 21.1 kg (n = 506, p < 0.001). Weight loss was 0.9 ± 2.8 kg (1.3%), 4.5 ± 4.3 kg (5.7%) and 7.9 ± 7.2 kg (7.5%), respectively, for those with a classification of normal weight (n = 67), overweight (n = 122) and obese (n = 307) at commencement. HbA1c reduced from 6.0 ± 1.2 to 5.6 ± 0.7% (n = 212, p < 0.001). For members with a commencing HbA1c of <5.7% (n = 110), 5.7−6.4% (n = 55), and ≥6.5% (n = 48), HbA1c reduced −0.1 ± 0.2%, −0.3 ± 0.3%, and −1.4 ± 1.3%, respectively. For members with a commencing HbA1c ≥6.5%, 90% experienced a HbA1c reduction and 54% achieved a final HbA1c < 6.5%. With inclusion and exclusion of metformin, respectively, 124 and 82 diabetes medications were prescribed to 63 and 42 members that reduced to 82 and 35 medications prescribed to 51 and 26 members at final visit. A health care professional delivered low-carbohydrate diet program can facilitate weight loss and improve glycaemic control with greatest improvements and clinical relevance in individuals with worse baseline parameters.

Identifying critical features of type two diabetes prevention interventions: A Delphi study with key stakeholders.

AIMS: This study aims to identify critically important features of digital type two diabetes mellitus (T2DM) prevention interventions. METHODS: A stakeholder mapping exercise was undertaken to identify key end-user and professional stakeholders, followed by a three-round Delphi procedure to generate and evaluate evidence statements related to the critical elements of digital T2DM prevention interventions in terms of product (intervention), price (funding models/financial cost), place (distribution/delivery channels), and promotion (target audiences). RESULTS: End-user (n = 38) and professional (n = 38) stakeholders including patients, dietitians, credentialed diabetes educators, nurses, medical doctors, research scientists, and exercise physiologists participated in the Delphi study. Fifty-two critical intervention characteristics were identified. Future interventions should address diet, physical activity, mental health (e.g. stress, diabetes-related distress), and functional health literacy, while advancing behaviour change support. Programs should be delivered digitally or used multiple delivery modes, target a range of population subgroups including children, and be based on collaborative efforts between national and local and government and non-government funded organisations. CONCLUSIONS: Our findings highlight strong support for digital health to address T2DM in Australia and identify future directions for T2DM prevention interventions. The study also demonstrates the feasibility and value of stakeholder-led intervention development processes.

Effectiveness and acceptability of continuous glucose monitoring for type 2 diabetes management: A narrative review.

The present narrative review discusses the role of continuous glucose monitoring (CGM) in glycemic and weight control, and lifestyle behavior adherence in adults with type 2 diabetes. A literature search from January 2001 to November 2017 was carried out (MEDLINE, CINAHL, Web of Science and Scopus). Eligible studies were trials evaluating the use of CGM with the aim of achieving glucose control or lifestyle-related treatment adherence over a period of ≥8 weeks in adults with type 2 diabetes compared with usual care or another comparison intervention, or observational trials reporting CGM user experience. A total of 5,542 participants were recruited into 11 studies (eight randomized controlled trials [n = 5,346] and three observational studies [n = 196]). The sample size ranged 6-4,678 participants, the mean age was 51.7-60.0 years and diabetes duration was 2.1-19.2 years, with high heterogeneity between studies. Overall, the available evidence showed, compared with traditional self-monitoring of blood glucose levels, CGM promoted greater reductions in glycated hemoglobin, bodyweight and caloric intake; higher adherence rating to a personal eating plan; and increases in physical activity. High compliance to CGM wear-time and device calibration was reported (>90%). The addition of lifestyle and/or behavioral counseling to CGM appeared to further potentiate these improvements. Preliminary evidence suggests that CGM use promotes glycemic and weight control, and lifestyle behavior adherence in adults with type 2 diabetes. These benefits might be further enhanced with integration of diet, exercise, and glucose excursion education and counseling. However, specific attributes of effective interventions and the application of CGM information for promoting improved outcomes and healthier choices remain unclear.

Cohort Analysis of a 24-Week Randomized Controlled Trial to Assess the Efficacy of a Novel, Partial Meal Replacement Program Targeting Weight Loss and Risk Factor Reduction in Overweight/Obese Adults.

Our aim was to design and evaluate a weight-loss program, including a partial meal replacement program, point-of-care testing and face-to-face and smartphone app support, appropriate for delivery in a community pharmacy setting. Overweight or obese adults (n = 146, 71.2% female, 48.18 ± 11.75 years old) were recruited to participate in a 24-week weight loss study and randomised to two app conditions. The dietary intervention was consistent regardless of app. Twelve weeks of clinic appointments with a trained consultant were followed by only app support for an additional 12 weeks. By week 24, retention was 57.5%. There were no differences between app conditions. Based on a cohort analysis of the trial, the mean decrease in weight from baseline to week 24 was 6.43 ± 1.06 kg for males (p < 0.001) and 5.66 ± 0.70 kg for females (p < 0.001). Mixed models also revealed decreases for LDL Cholesterol (-0.13 ± 0.08 mmol/L, nonsignificant), triglycerides (-0.08 ± 0.05 mmol/L, nonsignificant) and an increase in HDL cholesterol (+0.08 ± 0.04 mmol/L, ns) were not significant by week 24. Blood glucose (-0.23 ± 0.08 mmol/L, p = 0.040) and blood pressure (Systolic blood pressure -5.77 ± 1.21 Hg/mm, p < 0.001) were significantly lower at week 24 compared to baseline. Weight loss self-efficacy increased and remained significantly higher than baseline at week 24 (16.85 ± 2.93, p < 0.001). Overall, the program supported participants and was successful in achieving significant weight loss and improvements in health outcomes over 24 weeks.

Dairy Intake Enhances Body Weight and Composition Changes during Energy Restriction in 18-50-Year-Old Adults-A Meta-Analysis of Randomized Controlled Trials.

BACKGROUND/AIMS: A meta-analysis of randomized controlled trials (RCTs) was performed to investigate the effects of dairy food or supplements during energy restriction on body weight and composition in 18-50-year-old. METHODS: RCTs ≥ 4 weeks comparing the effect of dairy consumption (whole food or supplements) with control diets lower in dairy during energy restriction on body weight, fat and lean mass were identified by searching MEDLINE, EMBASE, Pubmed, Cochrane Central and World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) until March 2016. Reports were identified and critically appraised in duplicate. Data were pooled using random-effects meta-analysis. Chi²- and I²-statistics indicated heterogeneity. Dose effect was assessed using meta-regression analysis. GRADE guidelines were used to rate the quality (QR) of the evidence considering risk of bias, inconsistency, indirectness, imprecision, publication bias and effect estimates. RESULTS: 27 RCTs were reviewed. Participants consumed between 2 and 4 standard servings/day of dairy food or 20-84 g/day of whey protein compared to low dairy control diets, over a median of 16 weeks. A greater reduction in body weight (-1.16 kg [-1.66, -0.66 kg], p < 0.001, I² = 11%, QR = high, n = 644) and body fat mass (-1.49 kg [-2.06, -0.92 kg], p < 0.001, I² = 21%, n = 521, QR = high) were found in studies largely including women (90% women). These effects were absent in studies that imposed resistance training (QR = low-moderate). Dairy intake resulted in smaller loss of lean mass (all trials pooled: 0.36 kg [0.01, 0.71 kg], p = 0.04, I² = 64%, n = 651, QR = moderate). No between study dose-response effects were seen. CONCLUSIONS: Increased dairy intake as part of energy restricted diets resulted in greater loss in bodyweight and fat mass while attenuating lean mass loss in 18-50-year-old adults. Further research in males is needed to investigate sex effects.

Effects of acute and longer-term dietary restriction on upper gut motility, hormone, appetite, and energy-intake responses to duodenal lipid in lean and obese men.

BACKGROUND: A 4-d 70% energy restriction enhances gastrointestinal sensitivity to nutrients associated with enhanced energy-intake suppression by lipid. To our knowledge, it is unknown whether these changes occur with 30% energy restriction and are sustained in the longer term. OBJECTIVES: We hypothesized that 1) a 4-d 30% energy restriction would enhance effects of intraduodenal lipid on gastrointestinal motility, gut hormones, appetite, and energy intake in lean and obese men and 2) a 12-wk energy restriction associated with weight loss would diminish effects of acute energy restriction on responses to lipid in in obese men. DESIGN: Twelve obese males were studied before (day 0) and after 4 d (day 5), 4 wk (week 4), and 12 wk (week 12), and 12 lean males were studied before and after 4 d of consumption of a 30% energy-restricted diet. On each study day, antropyloroduodenal pressures, gut hormones, and appetite during a 120-min (2.86-kcal/min) intraduodenal lipid infusion and energy intake at a buffet lunch were measured. RESULTS: On day 5, fasting cholecystokinin was less, and ghrelin was higher, in lean (P < 0.05) but not obese men, and lipid-stimulated cholecystokinin and peptide YY and the desire to eat were greater in both groups (P < 0.05), with no differences in energy intakes compared with on day 0. In obese men, a 12-wk energy restriction led to weight loss (9.7 ± 0.7 kg). Lipid-induced basal pyloric pressures (BPPs), peptide YY, and the desire to eat were greater (P < 0.05), whereas the amount eaten was less (P < 0.05), at weeks 4 and 12 compared with day 0. CONCLUSIONS: A 4-d 30% energy restriction modestly affects responses to intraduodenal lipid in health and obesity but not energy intake, whereas a 12-wk energy restriction, associated with weight-loss, enhances lipid-induced BPP and peptide YY and reduces food intake, suggesting that energy restriction increases gastrointestinal sensitivity to lipid. This trial was registered at the Australian New Zealand Clinical Trials Registry (www.anzctr.org.au) as 12609000943246.

Examining participant engagement in an information technology-based physical activity and nutrition intervention for men: the manup randomized controlled trial.

BACKGROUND: Males experience a shorter life expectancy and higher rates of chronic diseases compared to their female counterparts. To improve health outcomes among males, interventions specifically developed for males that target their health behaviors are needed. Information technology (IT)-based interventions may be a promising intervention approach in this population group, however, little is known about how to maximize engagement and retention in Web-based programs. OBJECTIVE: The current study sought to explore attributes hypothesized to influence user engagement among a subsample of participants from the ManUp study, a randomized controlled trial testing the efficacy of an interactive Web-based intervention for promoting physical activity and nutrition among middle-aged males. METHODS: Semistructured interviews were conducted and audiotaped with 20 of the ManUp participants. Interview questions were based on a conceptual model of engagement and centered on why participants took part in the study, what they liked and did not like about the intervention they received, and how they think the intervention could be improved. Interview recordings were transcribed and coded into themes. RESULTS: There were five themes that were identified in the study. These themes were: (1) users' motives, (2) users' desired outcomes, (3) users' positive experiences, (4) users' negative emotions, and (5) attributes desired by user. CONCLUSIONS: There is little research in the field that has explored user experiences in human-computer interactions and how such experiences may relate to engagement, especially among males. Although not conclusive, the current study provides some insight into what personal attributes of middle-aged males (such as their key motives and goals for participating) and attributes of the intervention materials (such as usability, control, and interactivity) may impact on user engagement in this group. These findings will be helpful for informing the design and implementation of future health behavior interventions for males.

Outcomes of Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding.

AIM: To evaluate weight loss and surgical outcomes of Roux-en-Y gastric bypass (RYGB) and laparoscopic adjustable gastric band (LAGB). METHODS: Data relating to changes in body mass index (BMI) and procedural complications after RYGB (1995-2009; n = 609; 116M: 493F; 42.4 ± 0.4 years) or LAGB (2004-2009; n = 686; 131M: 555F; 37.2 ± 0.4 years) were extracted from prospective databases. RESULTS: Pre-operative BMI was higher in RYGB than LAGB patients (46.8 ± 7.1 kg/m² vs 40.4 ± 4.2 kg/m², P < 001); more patients with BMI < 35 kg/m² underwent LAGB than RYGB (17.1% vs 4.1%, P < 0.0001). BMI decrease was greater after RYGB. There were direct relationships between weight loss and pre-operative BMI (P < 0.001). Although there was no difference in weight loss between genders during the first 3-year post-surgery, male LAGB patients had greater BMI reduction than females (-8.2 ± 4.3 kg/m² vs -3.9 ± 1.9 kg/m², P = 0.02). Peri-operative complications occurred more frequently following RYGB than LAGB (8.0% vs 0.5%, P < 0.001); majority related to wound infection. LAGB had more long-term complications requiring corrective procedures than RYGB (8.9% vs 2.1%, P < 0.001). Conversion to RYGB resulted in greater BMI reduction (-9.5 ± 3.8 kg/m²) compared to removal and replacement of the band (-6.0 ± 3.0 kg/m²). Twelve months post-surgery, fasting glucose, total cholesterol and low density lipoprotein levels were significantly lower with the magnitude of reduction greater in RYGB patients. CONCLUSION: RYGB produces substantially greater weight loss than LAGB. Whilst peri-operative complications are greater after RYGB, long-term complication rate is higher following LAGB.

A review of the effectiveness of physical activity interventions for adult males.

Physical inactivity is one of the main modifiable risk factors for a range of noncommunicable diseases. Of particular interest are adult males, a hard-to-reach population group for health promotion interventions. The purpose of this review is to provide a critical evaluation of the published health-related physical activity interventions that have targeted adult males. A comprehensive search of MEDLINE, CINAHL®, ScienceDirect, Web of Science, PsycINFO, the Cochrane Library, and SPORTDiscus™ was conducted for intervention studies published in English, between January 1990 and August 2010. Studies including community-dwelling adult men (≥ 18 years), or including both males and females where data on male participants could be extracted and examined, were included in this review. Studies assessing changes in levels of physical activity, physical fitness or changes in biomarkers of disease risk relevant to physical activity (e.g. body weight, waist circumference, lipids, blood pressure) were the primary focus. A total of 14 studies focusing on physical activity only and nine combined physical activity and nutrition studies were also included in this review. Ten of the 14 physical activity only studies and four of the nine combined physical activity and nutrition studies demonstrated significant increases in physical activity outcomes. Face-to-face, group-based and print-based methods were most commonly employed in these interventions. Within each mode of delivery, a number of elements including regular feedback, access to self-monitoring tools, elements of social support, variety in activities and a degree of friendly competition, were revealed as positive inclusions for this population group. Males are generally under-represented in health-promotion interventions and should therefore be targeted specifically, and while results of the included studies are encouraging, there is a lack of intervention studies targeting adult males. Further research into this population group is therefore required.
