"What Came First?" Population-Based Evaluation of Health Care Encounters for Depression and Anxiety Before and After Inflammatory Arthritis Diagnosis: Disentangling the Relationship Between Mental Health and Arthritis.

OBJECTIVE: The study objective was to describe patterns of depression and anxiety health care use before and after diagnosis among patients with inflammatory arthritis (IA), namely, ankylosing spondylitis, psoriatic arthritis, and rheumatoid arthritis. METHODS: We used population-based linked administrative health data from British Columbia, Canada, to build a cohort of individuals (≥18 years) with incident IA and individuals without IA ("IA-free controls") matched on age and sex. We computed the proportion of individuals with IA and controls who had one or more depression or one or more anxiety health care encounters and the use of one or more antidepressants or one or more anxiolytics in each yearly interval five years before and after IA diagnosis. We used multivariable logistic regression models to evaluate the association between IA status and aforementioned depression and anxiety health care use outcomes in each yearly interval. RESULTS: A total of 80,238 individuals with IA (62.9% female; mean ± SD age 56.2 ± 16.7 years) and 80,238 IA-free controls (62.9% female; mean ± SD age 56.2 ± 16.6 years) were identified between January 1, 2001, and March 31, 2018. Individuals with IA had significantly increased odds of depression and anxiety health care encounters and dispensation of antidepressants and anxiolytics for each yearly interval before and after diagnosis. Adjusted odds ratios (ORs) were highest in the year immediately before (one or more depression visits: adjusted OR 1.61, 95% confidence interval [CI] 1.55-1.66; one or more anxiolytics: adjusted OR 1.71, 95% CI 1.66-1.77) or after (one or more antidepressants: adjusted OR 1.95, 95% CI 1.89-2.00) IA diagnosis. CONCLUSION: Findings suggest a role for depression and anxiety in characterizing the IA prodrome period and generate hypotheses regarding overlapping biopsychosocial processes that link IA and mental health comorbidities.

Supporting and Incentivizing Peer Leaders for an Internet-Based Private Peer Community for Youths With Type 1 Diabetes: Social Network and Directed Content Analysis.

BACKGROUND: Youths with type 1 diabetes (T1D) frequently experience stigma. Internet-based peer communities can mitigate this through social support but require leaders to catalyze exchange. Whether nurturing potential leaders translates into a central role has not been well studied. Another issue understudied in such communities is lurking, the viewing of exchanges without commenting or posting. OBJECTIVE: We aimed to assess the centrality of the peer leaders we selected, trained, and incentivized within the Canadian Virtual Peer Network (VPN)-T1D. This is a private Facebook (Meta Platforms, Inc) group that we created for persons aged 14 to 24 years with T1D. We specifically sought to (1) compare a quantitative estimate of network centrality between peer leaders and regular members, (2) assess the proportions of network exchanges that were social support oriented, and (3) assess proportions of high engagement (posts, comments, reactions, and votes) and low engagement (lurking) exchanges. METHODS: We recruited peer leaders and members with T1D from prior study cohorts and clinics. We trained 10 leaders, provided them with a monthly stipend, and encouraged them to post on the private Facebook group we launched on June 21, 2017. We extracted all communications (posts, messages, reactions, polls, votes, and views) that occurred until March 20, 2020. We calculated each member's centrality (80% of higher engagement communications comprising posts, comments, and reactions plus 20% of members with whom they connected). We divided each member's centrality by the highest centrality to compute the relative centrality, and compared the mean values between leaders and members (linear regression). We calculated the proportions of communications that were posts, comments, reactions, and views without reaction. We performed content analysis with a social support framework (informational, emotional, esteem-related, network, and tangible support), applying a maximum of 3 codes per communication. RESULTS: VPN-T1D gained 212 regular members and 10 peer leaders over 33 months; of these 222 members, 26 (11.7%) exited. Peer leaders had 10-fold higher relative centrality than regular members (mean 0.53, SD 0.26 vs mean 0.04, SD 0.05; 0.49 difference; 95% CI 0.44-0.53). Overall, 91.4% (203/222) of the members connected at least once through posts, comments, or reactions. Among the 75,051 communications, there were 5109 (6.81%) posts, comments, and polls, 6233 (8.31%) reactions, and 63,709 (84.9%) views (lurking). Moreover, 54.9% (3430/6253) of codes applied were social support related, 66.4% (2277/3430) of which were informational (eg, insurance and travel preparation), and 20.4% (699/3430) of which were esteem related (eg, relieving blame). CONCLUSIONS: Designating, training, and incentivizing peer leaders may stimulate content exchange and creation. Social support was a key VPN-T1D deliverable. Although lurking accounted for a high proportion of the overall activity, even those demonstrating this type of passive participation likely derived benefits, given that the network exit rate was low.

Longitudinal associations between paternal mental health and child behavior and cognition in middle childhood.

Introduction: Paternal mental health has been associated with adverse consequences on offspring psychosocial development, and family environmental factors may partly explain those associations. To clarify this, we need comprehensive prospective studies, particularly in middle-childhood when the child enters school and is expected to make use of behavioral and cognitive skills as part of their interactions and learning. Method: Using data from a sub-sample of the prospective 3D birth cohort study comprised of mother-father-child triads, and a follow-up of the parents and the children at 6-8 years of age (n = 61; 36 boys, 25 girls), we examined whether paternal anxious and depressive symptoms measured during the pregnancy period (i.e., prenatally) or concurrently when the child was assessed at 6-8 years old were associated with children's cognition/behavior. Results: In contrast to our hypotheses, we found that greater prenatal paternal depressive symptoms predicted fewer child behavioral difficulties; and that greater concurrent childhood paternal depression or anxiety symptoms were associated with higher child full-scale IQ, controlling for the equivalent maternal mental health assessment and parental education. Father parenting perception did not mediate these associations, nor were they moderated by maternal mental health at the concurrent assessment, or paternal ratings of marital relationship quality. Discussion: These findings suggest that higher symptoms of paternal mental health symptoms are associated with fewer child behavioral difficulties and higher cognitive performance in middle childhood. Potential clinical implications and future research directions are discussed.

Medical Cannabis Use Among Canadian Veterans and Non-Veterans: A National Survey.

Background: Medical cannabis (MC) is used by Canadian Veterans to manage a wide range of health issues. However, there is little information comparing the reasons for MC use and its perceived effectiveness between Veterans and non-Veterans. Objects: We compared MC use among a convenience sample of Canadian Veterans and with non-Veteran controls, including demographics, reasons and patterns of use, and perceived effectiveness. Methods: Between November and December 2021, Canadian Veterans using cannabis were invited to participate in a survey using a national press release, social media, and announcements on online platform dedicated to promoting health among Canadian Veterans and non-Veterans during the pandemic (www.MissionVav.com). The survey was also mentioned in a monthly newsletter from Veteran Affairs Canada. Self-reported effectiveness was evaluated using a 0 to 10 visual analogue scale (0 being not all effective, 10 being the most effective). Results: The survey was completed by 157 people, including 108 (69%) males and 49 (31%) females. The mean age was 57 years (range 19 to 84). Among responders, 90 (63%) identified as Veterans. The most common reasons for MC use among Veterans included: insomnia (80%), anxiety (73%), and depression (52%). Veterans reported medical conditions such as chronic pain (88%) and arthritis (51%). Compared with non-Veterans, Veterans were significantly more likely to be male (83% vs. 49%), have a higher BMI (35.2 vs. 30.9), to report problems with sleep, anxiety, depression, and PTSD, and to use cannabis in edible form (51% vs. 22%). Self-reported mean effectiveness scores for MC were highest for PTSD (8.4), insomnia (8.2), anxiety (8.1), depression (8.0), and chronic pain (7.6). Conclusions: We found important differences in user characteristics and cannabis use patterns between Canadian Veterans and non-Veterans. Further controlled studies are required to validate these findings, but these data suggest that orally administered cannabis products may be worth further study.

Qualitative study exploring the perspectives of emerging adults with type 1 diabetes after transfer to adult care from a paediatric diabetes centre in Montreal, Canada.

INTRODUCTION: Among youth living with type 1 diabetes (T1D), the increasing demands to diabetes self-care and medical follow-up during the transition from paediatric to adult care has been associated with greater morbidity and mortality. Inadequate healthcare support for youth during the transition care period could exacerbate psychosocial risks and difficulties that are common during emerging adulthood. The current investigation sought to explore the post-transfer perceptions of emerging adults living with T1D relating to their transition to adult care. RESEARCH DESIGN AND METHODS: Thirty-three emerging adults living with T1D were recruited during paediatric care and contacted for a semistructured interview post-transfer to adult care (16.2±4.2 months post-transfer) in Montreal, Canada. We analysed data using thematic analysis. RESULTS: We identified four key themes: (1) varied perceptions of the transition process from being quick and abrupt with minimal advice or information from paediatric healthcare providers (HCP) to more positive including a greater motivation for self-management and the transition being concurrent with the developmental period; (2) facilitators to the transition process included informational and tangible social support from HCPs and family or friends, a positive relationship with adult HCP and a greater ease in communicating with the adult care clinic or adult HCP; (3) barriers to adequate transition included lack of advice or information from paediatric HCPs, loss of support from HCPs and friends or family, the separation of healthcare services and greater difficulty in making appointments with adult clinic or HCP and (4) participants recommendations for improving the transition included increasing the length and frequency of appointments in adult care, having access to educational information, and better transition preparation from paediatric HCPs. CONCLUSIONS: The experiences and perceptions of emerging adults are invaluable to guide the ongoing development and improvement of transition programmes for childhood-onset chronic illnesses.

Adaptation of an Adult Web Application for Type 1 Diabetes Self-management to Youth Using the Behavior Change Wheel to Tailor the Needs of Health Care Transition: Qualitative Interview Study.

BACKGROUND: Youth (aged 14-24 years) living with type 1 diabetes (T1D) encounter increased challenges in their diabetes self-management (DSM), especially during the transition to adult care. Although DSM education and support are imperative, there is insufficient information on how web-based digital tools tailored to their demands can be developed. OBJECTIVE: On the basis of the Behavior Change Wheel, this study aims to identify, among youth living with T1D, the needs and factors influencing their DSM in the context of health care transition and to inform the adaptation (content and features) of an adult self-guided web application (Support). METHODS: Internet-based semistructured individual interviews based on a phenomenological study design were conducted with 21 youths, and transcripts were analyzed using an inductive approach with concept mapping. RESULTS: Factors influencing T1D self-management were categorized into barriers and facilitators and then as external or internal. Features influencing the accessibility to information, increasing the sense of support, and use of the tool were positively accepted. Features unrelated to their expectations of digital tool use or difficulty navigating were viewed negatively. Participants expressed an interest in reliable, practical, and novel educational content. Although youth considered the information provided by medical professionals to be important, peer exchange was deemed necessary to obtain a practical perspective and real-life examples. CONCLUSIONS: Compared with the adult population, in addition to tailored content and a simplified information search process, when building a DSM education and support digital tool for youth, features should be selected to encourage supervised peer exchange.

Impact of Loneliness and Social Isolation on Mental Health Outcomes Among Individuals With Rheumatic Diseases During the COVID-19 Pandemic.

OBJECTIVE: The study objective was to assess mental and social health outcomes for individuals with rheumatic disease during the COVID-19 pandemic and evaluate the relationship of loneliness and social isolation with depression and anxiety. METHODS: We administered an international cross-sectional online survey to individuals with rheumatic disease(s) (≥18 years) between April 2020 and September 2020, with a follow-up survey from December 2020 to February 2021. We used questionnaires to evaluate loneliness (3-item UCLA Loneliness Scale [UCLA-3]), social isolation (Lubben Social Network Scale [LSNS-6]), depression (Patient Health Questionnaire [PHQ-9]), and anxiety (Generalized Anxiety Disorder 7-item [GAD-7] Scale). We used multivariable linear regression models to evaluate the cross-sectional associations of loneliness and social isolation with depression and anxiety at baseline. RESULTS: Seven hundred eighteen individuals (91.4% women, mean age: 45.4 ± 14.2 years) participated in the baseline survey, and 344 completed the follow-up survey. Overall, 51.1% of participants experienced loneliness (UCLA-3 score ≥6) and 30.3% experienced social isolation (LSNS-6 score <12) at baseline. Depression (PHQ-9 score ≥10) and anxiety (GAD-7 score ≥10) were experienced by 42.8% and 34.0% of participants at baseline, respectively. Multivariable models showed that experiencing both loneliness and social isolation, in comparison to experiencing neither, was significantly associated with an average 7.27 higher depression score (ß = 7.27; 95% confidence interval [CI]: 6.08-8.47) and 5.14 higher anxiety score (ß = 5.14; 95% CI: 4.00-6.28). CONCLUSION: Aside from showing substantial experience of loneliness and social isolation during the COVID-19 pandemic, our survey showed significant associations with depression and anxiety. Patient supports to address social health have potential implications for also supporting mental health.

A pilot randomized controlled trial of a lay telephone coaching and web-based intervention for postpartum depression and anxiety: The MPOWER study.

Background: Mental health problems are frequent in the postpartum period, but accessible treatment options are lacking. The MPOWER study investigated whether the use of trained lay coaches could increase the uptake and effectiveness of a web-based intervention (WBI) for women with postpartum depression and/or anxiety. Objectives: First, to compare the feasibility and acceptability of a WBI for women with postpartum depression and anxiety, with and without the addition of telephone coaching calls. Second, to estimate the effectiveness of the WBI at decreasing symptoms of depression and anxiety at 6 months, with and without coaching calls. Methods: We conducted a pilot randomized controlled trial (RCT) that enrolled women who had recently given birth and had mild to moderate postpartum depression and/or anxiety. Study participants were provided access to the WBI. Women randomized to the intervention group also received up to 7 telephone coaching calls during the 6 months of follow up. We evaluated the feasibility of the intervention through participants' usage of the WBI, as well as the completion and fidelity of planned coach calls. We measured acceptability via two questionnaires on the usability of the WBI and participant satisfaction with the intervention. To determine the potential effectiveness of the intervention, the primary outcomes were defined as symptoms of depression and anxiety at 6 months and adjusted mean differences between groups for these outcomes were estimated using linear regression models. Results: We recruited 52 participants (25 intervention; 27 control). At 6 months, 88 % (22/25) of participants randomized to the intervention arm and 59 % (16/27) of participants randomized to the control arm remained in the study. The intervention group had an average of 11 (95 % CI: [5, 18]) more website logins than the control group. Intervention group participants completed a mean of 6.2 coaching calls with high fidelity. The estimates of the effect of the intervention on mental health outcomes at 6-months were imprecise but point estimates and confidence intervals were consistent with a moderate beneficial effect of the intervention on both symptoms of depression and anxiety (fully adjusted effects sizes: 0.51 (95 % CI: [-0.14, 1.17]) and 0.56 (95 % CI: [-0.09, 1.22]), respectively). Conclusions: WBIs with coaching are feasible, acceptable, and potentially effective treatment options for women with mild to moderate postpartum depression and/or anxiety. The addition of coaching calls markedly increased engagement with the WBI, but a larger RCT is needed to determine the effectiveness of such an intervention.

Study protocol for the sheMATTERS study (iMproving cArdiovascular healTh in new moThERS): a randomized behavioral trial assessing the effect of a self-efficacy enhancing breastfeeding intervention on postpartum blood pressure and breastfeeding continuation in women with hypertensive disorders of pregnancy.

BACKGROUND: Individuals with hypertensive disorders of pregnancy (HDP) have an elevated lifetime risk of chronic hypertension, metabolic syndrome, and premature cardiovascular disease. Because breastfeeding duration and exclusivity have been associated in observational studies with improved cardiovascular health, optimizing breastfeeding in those with HDP might be an unrealized cardio-prevention approach, in particular because individuals with HDP have more breastfeeding challenges. Breastfeeding supportive interventions targeting one's breastfeeding self-efficacy have been shown to improve breastfeeding rates. METHODS: We designed an open-label, multi-center 1:1 randomized behavioral trial to test whether a previously validated self-efficacy enhancing breastfeeding intervention can improve breastfeeding duration and/or exclusivity, and lower postpartum blood pressure at 12 months. Randomization is computer-generated and stratified by site (four hospitals in Montreal, Quebec and one hospital in Kingston, Ontario; all in Canada). Included are breastfeeding participants with HDP (chronic/gestational hypertension or preeclampsia) who delivered a live singleton infant at > 34 weeks, speak English or French, and have no contraindications to breastfeeding. Informed and written consent is obtained at hospitalization for delivery or a re-admission with hypertension within 1 week of discharge. Participants assigned to the intervention group receive a breastfeeding self-efficacy-based intervention delivered by a trained lactation consultant in hospital, with continued reactive/proactive support by phone or text message for up to 6 months postpartum. Regardless of group assignment, participants are followed for self-reported outcomes, automated office blood pressure, and home blood pressure at several time points with end of follow-up at 12 months. DISCUSSION: This study will assess whether an intensive nurse-led behavioral intervention can improve breastfeeding rates and, in turn, postpartum blood pressure - an early marker for atherosclerotic cardiovascular disease. If effective, this form of enhanced breastfeeding support, along with closer BP and metabolic surveillance, can be implemented broadly in individuals lactating after HDP.

Measuring the Impact of MyLupusGuide in Canada: Results of a Randomized Controlled Study.

OBJECTIVE: This study was undertaken to assess the effects of a web-based program, MyLupusGuide, developed to facilitate self-management in systemic lupus erythematosus (SLE). METHODS: In this randomized controlled online study, participants received either immediate access to the MyLupusGuide site or delayed access starting on month 3. The primary outcome was the patient activation measure (PAM) score. Secondary outcomes included measurements of health status, self-efficacy, coping, perceived patient-physician relationship, and medication adherence. Outcomes were measured at the baseline visit and at the 3-month and 6-month follow-up visits. We used linear mixed modeling to compare PAM scores between the 2 groups at months 3 and 6. RESULTS: There were 541 participants included in this study. The mean ± SE age was 50 ± 14 years; 93% were female and 74% were White. The mean ± SE disease duration was 17 ± 12 years, and 56% visited MyLupusGuide at least once. The baseline mean ± SE PAM score was 61.2 ± 13, with 36% scoring low for perceived self-management skills. After 3 months of exposure to MyLupusGuide, there were no differences in terms of PAM scores between groups. In exploratory analyses, we found significant improvement in PAM scores in those who had low PAM scores at baseline and in male individuals. We observed significant improvements in self-efficacy before and after access to MyLupusGuide and delayed improvements at month 6 compared to month 3 in terms of mental health and emotional coping. CONCLUSION: MyLupusGuide increases self-efficacy but not patient activation. A total of 56% of participants visited the MyLupusGuide site during the study period. Individuals with lupus need support to become activated toward self-management behaviors.

'How did you cope with such concerns?': insights from a monitored online infertility peer support forum.

The Research Question posed was 'What coping strategies do fertility patients and trained peer supporters discuss in an online infertility peer support forum?' A thematic analysis was used to examine 244 online posts from a sample of 39 users (37 women and two men) for themes in coping with fertility-related stressors. Data were collected from Connect, a monitored online discussion forum with trained peer supporters. Connect users ranged from 27 to 44 years of age (mean = 34.38) and 33 (84.6%) were nulliparous at the time of the study. A variety of cognitive-reappraisal and practical management coping strategies was discussed across four themes: (i) balancing interpersonal relationships; (ii) partner support; (iii) uncertainty and lack of control; and (iv) positivity and negativity. Experiences of uncertainty and lack of control related to time and schedule, outcomes and waiting for physical symptoms, and the clinic. Connect users commonly discussed the helpfulness of coping strategies. Connect users actively requested experiential information about ways of coping from other patients and peer supporters, highlighting the importance of lived experience to those currently in treatment. Findings support conceptualizations of infertility coping as a process that is unique to the infertility treatment context and that may change throughout a patient's treatment. Trained peer supporters may benefit fertility patients by normalizing, reappraising, and providing practical strategies to ameliorate difficult infertility-related challenges.

Remission of type 2 diabetes and improved diastolic function by combining structured exercise with meal replacement and food reintroduction among young adults: the RESET for REMISSION randomised controlled trial protocol.

INTRODUCTION: Type 2 diabetes mellitus (T2DM) onset before 40 years of age has a magnified lifetime risk of cardiovascular disease. Diastolic dysfunction is its earliest cardiac manifestation. Low energy diets incorporating meal replacement products can induce diabetes remission, but do not lead to improved diastolic function, unlike supervised exercise interventions. We are examining the impact of a combined low energy diet and supervised exercise intervention on T2DM remission, with peak early diastolic strain rate, a sensitive MRI-based measure, as a key secondary outcome. METHODS AND ANALYSIS: This prospective, randomised, two-arm, open-label, blinded-endpoint efficacy trial is being conducted in Montreal, Edmonton and Leicester. We are enrolling 100 persons 18-45 years of age within 6 years' T2DM diagnosis, not on insulin therapy, and with obesity. During the intensive phase (12 weeks), active intervention participants adopt an 800-900 kcal/day low energy diet combining meal replacement products with some food, and receive supervised exercise training (aerobic and resistance), three times weekly. The maintenance phase (12 weeks) focuses on sustaining any weight loss and exercise practices achieved during the intensive phase; products and exercise supervision are tapered but reinstituted, as applicable, with weight regain and/or exercise reduction. The control arm receives standard care. The primary outcome is T2DM remission, (haemoglobin A1c of less than 6.5% at 24 weeks, without use of glucose-lowering medications during maintenance). Analysis of remission will be by intention to treat with stratified Fisher's exact test statistics. ETHICS AND DISSEMINATION: The trial is approved in Leicester (East Midlands - Nottingham Research Ethics Committee (21/EM/0026)), Montreal (McGill University Health Centre Research Ethics Board (RESET for remission/2021-7148)) and Edmonton (University of Alberta Health Research Ethics Board (Pro00101088). Findings will be shared widely (publications, presentations, press releases, social media platforms) and will inform an effectiveness trial. TRIAL REGISTRATION NUMBER: ISRCTN15487120.

Depression, diabetes and immigration status: a retrospective cohort study using the Canadian Longitudinal Study on Aging.

BACKGROUND: A bidirectional association between depression and diabetes exists, but has not been evaluated in the context of immigrant status. Given that social determinants of health differ between immigrants and nonimmigrants, we evaluated the association between diabetes and depression incidence, depression and diabetes incidence, and whether immigrant status modified this association, among immigrants and nonimmigrants in Canada. METHODS: We employed a retrospective cohort design using data from the Canadian Longitudinal Study on Aging Comprehensive cohort (baseline [2012-2015] and 3-year follow-up [2015-2018]). We defined participants as having diabetes if they self-reported it or if their glycated hemoglobin A1c level was 7% or more; we defined participants as having depression if their Center for Epidemiological Studies Depression score was 10 or higher or if they were currently undergoing depression treatment. We excluded those with baseline depression (Cohort 1) and baseline diabetes (Cohort 2) to evaluate the associations between diabetes and depression incidence, and between depression and diabetes incidence, respectively. We constructed logistic regression models with interaction by immigrant status. RESULTS: Cohort 1 (n = 20 723; mean age 62.7 yr, standard deviation [SD] 10.1 yr; 47.6% female) included 3766 (18.2%) immigrants. Among immigrants, 16.4% had diabetes, compared with 15.6% among nonimmigrants. Diabetes was associated with an increased risk of depression in nonimmigrants (adjusted odds ratio [OR] 1.27, 95% confidence interval [CI] 1.08-1.49), but not in immigrants (adjusted OR 1.12, 95% CI 0.80-1.56). Younger age, female sex, weight change, poor sleep quality and pain increased depression risk. Cohort 2 (n = 22 054; mean age 62.1 yr, SD 10.1 yr; 52.2% female) included 3913 (17.7%) immigrants. Depression was associated with an increased risk of diabetes in both nonimmigrants (adjusted OR 1.39, 95% CI 1.16-1.68) and immigrants (adjusted OR 1.60, 95% CI 1.08-2.37). Younger age, male sex, waist circumference, weight change, hypertension and heart disease increased diabetes risk. INTERPRETATION: We found an overall bidirectional association between diabetes and depression that was not significantly modified by immigrant status. Screening for diabetes for people with depression and screening for depression for those with diabetes should be considered.

Hypertensive disorders of pregnancy and breastfeeding practices: A secondary analysis of data from the All Our Families Cohort.

INTRODUCTION: Hypertensive disorders of pregnancy occur in approximately 7%-10% of pregnancies and are associated with adverse maternal cardiovascular health outcomes across the lifespan. In contrast, breastfeeding has been associated with a reduction in cardiovascular risk factors in a dose-dependent manner. Despite the potential protective effects of lactation on cardiovascular risk, how hypertensive disorders of pregnancy relate to breastfeeding practices and experiences is not well understood. The aim of this study was to investigate the association between hypertensive disorders of pregnancy and breastfeeding outcomes in the first year postpartum. MATERIAL AND METHODS: We conducted a secondary analysis of prospective data from the All Our Families Cohort, a population-based study conducted in Calgary, Alberta, Canada. Women with a singleton pregnancy (n = 1418) who completed self-report questionnaires at <25 weeks and 34-36 weeks of gestation, and 4 months and 12 months postpartum, and provided consent to link to electronic medical records that identified diagnoses of hypertensive disorders of pregnancy (n = 122). Logistic and multiple linear regression analyses were used to model associations between hypertensive disorders of pregnancy and breastfeeding outcomes. Outcomes included breastfeeding intention, intended duration, exclusive breastfeeding at 4 months, breastfeeding duration at 12 months and breastfeeding difficulties. RESULTS: Hypertensive disorders of pregnancy were not associated with breastfeeding intention (odds ration [OR] 1.30, 95% confidence interval [CI] 0.47-3.03, P = 0.57), intended breastfeeding duration (b = -3.28, 95% CI -7.04 to 0.48, P = 0.09), or initiation (OR = 0.64, 95% CI 0.29- 1.65, P = 0.32), but were associated with an increase in the odds of non-exclusive breastfeeding at 4 months postpartum (OR = 2.11, 95% CI 1.39-3.22, P < 0.001). Women with hypertensive disorders breastfed for 6.26 (95% CI -10.00 to -2.51, P < 0.001) weeks less over 12 months postpartum, had significantly higher odds of reporting insufficient milk supply (OR = 1.75, 95% CI 1.19-2.46, P < 0.05) and had lower odds of breast and/or nipple pain (OR = 0.66, 95% CI 0.44-0.92, P < 0.05) compared with those without hypertensive disorders of pregnancy. CONCLUSIONS: Hypertensive disorders of pregnancy are associated with altered breastfeeding practices and experiences during the first year postpartum. Further research is needed to examine biopsychosocial mechanisms through which hypertensive disorders associate with shorter breastfeeding duration, and to examine whether greater breastfeeding duration, intensity or exclusivity reduces short- or long-term maternal cardiovascular risk.

Maternal anxiety, depression and vascular function during pregnancy.

OBJECTIVE: We aim to clarify whether type and timing of mental health symptoms in early pregnancy distinctly contribute to maternal-fetal vascular function, independent from the psychotropic medications given to treat these conditions. METHODS: Data from a prospective cohort study (n = 1678) were used to test whether self-reported fears about giving birth and depressive symptoms prior to 16 weeks of gestation were associated with vascular outcomes predictive of hypertensive disorders of pregnancy (HDP) i.e., systolic and diastolic blood pressure (BP); uterine artery pulsatility index (UAPI); umbilical artery resistance index (UmbARI); and urine protein creatinine ratio. Multiple linear regressions models and mediation models were used to test for associations between predictors and outcomes, controlling for previously identified risk factors for vascular dysfunction such as maternal age and history of infertility. RESULTS: Fears about giving birth in early pregnancy were inversely associated with UmbARI (ß = -0.33, p = 0.03, df = 51) mid- to late-pregnancy (≥20 weeks). Depressive symptoms in early pregnancy were also inversely associated with maternal systolic BP (ß = -0.13, p = 0.01, df = 387) and diastolic BP (ß = -0.10, p = 0.04, df = 387) during the first trimester. CONCLUSIONS: While fears about giving birth in early pregnancy were associated with lower vascular resistance in the fetal-placental unit, early depressive symptoms were associated with lower maternal vascular tone. At the very least, our results support the notion that early maternal psychological distress is unlikely to account for the development of HDP later during pregnancy and provide preliminary evidence to support distinct roles of pregnancy-related anxiety and depressive symptoms in maternal-fetal vascular function.

Parity and Psychosocial Risk Factors Increase the Risk of Depression During Pregnancy Among Recent Immigrant Women in Canada.

Prior investigations have examined risk factors associated to postpartum depression in immigrant women, but depression during pregnancy has received less attention. This study describes the prevalence and early determinants of antenatal depression among recent (≤ 5 years) and long-term immigrants (> 5 years), compared to Canadian-born women. 503 women completed standardized self-report questionnaires measuring sociodemographics and psychosocial factors. Multivariate logistic regressions identified first trimester risk factors for depression in each immigrant group. The prevalence of depressive symptoms was highest for recent immigrant (25.3-30.8%) compared to long-term immigrant (16.9-19.2%) and Canadian-born women (11.7-13.8%). Among recent immigrants, multiparity, higher stress and pregnancy-specific anxiety in early pregnancy increased the risk of antenatal depression. Among long-term immigrants, stress in the first trimester was significantly associated with antenatal depressive symptoms. Knowledge of modifiable risk factors (pregnancy-specific anxiety and stress) may help improve antenatal screening and inform the development of tailored interventions to meet the mental health needs of immigrant women during the perinatal period.

Maternal blood pressure trajectories and associations with gestational age at birth: a functional data analytic approach.

BACKGROUND: Research has revealed group-level differences in maternal blood pressure trajectories across pregnancy. These trajectories are typically constructed using clinical blood pressure data and multivariate statistical methods that are prone to bias and ignore the functional, dynamic process underlying a single blood pressure observation. The aim of this study was to use functional data analysis to explore blood pressure variation across pregnancy, and multivariate methods to examine whether trajectories are related to gestational age at birth. METHODS: Clinical blood pressure observations were available from 370 women who participated in a longitudinal pregnancy cohort study conducted in Montreal, Quebec, Canada. Functional data analysis was used to smooth blood pressure data and then to conduct a functional principal component analysis to examine predominant modes of variation. RESULTS: Three eigenfunctions explained greater than 95% of the total variance in blood pressure. The first accounted for approximately 80% of the variance and was characterized by a prolonged-decrease trajectory in blood pressure; the second explained 10% of the variance and captured a late-increase trajectory; and the third accounted for approximately 7% of the variance and captured a mid-decrease trajectory. The prolonged-decrease trajectory of blood pressure was associated with older, and late-increase with younger gestational age at birth. CONCLUSION: Functional data analysis is a useful method to model repeated maternal blood pressure observations and many other time-related cardiovascular processes. Results add to previous research investigating blood pressure trajectories across pregnancy through identification of additional, potentially clinically important modes of variation that are associated with gestational age at birth.

Adaptive web-based stress management programs among adults with a cardiovascular disease: A pilot Sequential Multiple Assignment Randomized Trial (SMART).

OBJECTIVE: To assess the feasibility and acceptability of using a Sequential Multiple Assignment Randomized Trial (SMART) to optimize the delivery of a web-based, stress management intervention for patients with a cardiovascular disease (CVD). METHODS: 59 patients with a CVD and moderate stress were randomized to a self-directed web-based stress management program (n = 30) or the same intervention plus lay telephone coaching (n = 29). After 6 weeks, non-responders were re-randomized to continue with their initial intervention or switched to motivational interviewing (MI). Feasibility, acceptability, and clinical significance were assessed. RESULTS: SMART procedures were feasible. Attrition rates were almost twice as high in the web-only group than the lay coach group. This might be because of the low satisfaction (47%) in the web-only group. On average, 1.7/5 modules were completed. Effect sizes for stress and quality of life generally exceeded 0.2 (clinical benchmark), except for the group that initially received lay coaching and then switched to MI. CONCLUSIONS: Results suggest that a larger trial would be feasible. Issues pertaining to attrition and satisfaction for non-responders need to be addressed. PRACTICE IMPLICATIONS: Findings contribute to the evidence on how best to develop and deliver e-Health interventions to maximize their efficacy while remaining cost-effective.

Challenges of Perceived Self-Management in Lupus.

OBJECTIVE: Systemic lupus erythematosus is a chronic autoimmune disease with varied and unpredictable levels of disease activity. The ability to self-manage lupus is important in controlling disease activity. Our objective was to determine levels of patient activation toward self-management in lupus. METHODS: We used baseline results from the MyLupusGuide study, which had recruited 541 lupus patients from 10 lupus centers. We used the Patient Activation Measure (PAM), a validated self-reported tool designed to measure activation toward self-management ability, as our primary variable and examined its association with demographic, disease-related, patient-provider communication and psychosocial variables captured in our study protocol. Univariable and multivariable linear regressions were performed using linear mixed models, with a random effect for centers. RESULTS: The mean ± SD age of participants was 50 ± 14 years, 93% were female, 74% were White, and the mean ± SD disease duration was 17 ± 12 years. The mean ± SD PAM score was 61.2 ± 13.5, with 36% of participants scoring in the 2 lower levels, indicating low activation. Variables associated with low activation included being single, having lower physical health status, lower self-reported disease activity, lower self-efficacy, use of more emotional coping and fewer distraction and instrumental coping strategies, and a perceived lack of clarity in patient-doctor communication. CONCLUSION: Low patient activation was observed in more than one-third of lupus patients, indicating that a large proportion of patients perceived that they are lacking in lupus self-management skills. These results highlight a modifiable gap in perceived self-management ability among patients with lupus.

Workplace experience of parents coping with perinatal loss: A scoping review.

BACKGROUND: Perinatal loss affects many parents in the workforce. Yet, current knowledge about their workplace experience while facing this difficult event is sparse. OBJECTIVES: The goal of this study was to review and synthesize the extent of scientific literature on the specific experiences of workers coping with perinatal loss and the resulting bereavement. METHODS: A scoping review was carried out using eight different databases. A total of 15 references, all using a qualitative methodology, were identified. RESULTS: Most of the references focused on the experience of mothers and on late perinatal loss (from the 20th week of pregnancy). All references highlighted the taboo and the non-recognition of perinatal grief and bereavement in both organizational practices and interpersonal relationships with colleagues and immediate supervisors. They also emphasized the difficulties associated with returning to work after the loss and the significant changes in the meaning attributed to work. CONCLUSIONS: While the studies included in this review clearly indicate that perinatal loss can affect working life, larger, quantitative studies are needed to quantify this phenomenon and its impact on employees and their organizations.
