'Black Out Rage Gallon' (aka borg): An investigation of a risky drinking trend on TikTok.

ISSUE ADDRESSED: A 'Black Out Rage Gallon' (borg) is a customised, individual alcoholic beverage popularised on TikTok, whereby half the water in a gallon jug is replaced with alcohol (usually spirits), flavourings, electrolytes and caffeine. We investigated the characteristics and portrayal of the emerging alcohol trend associated with the hashtag descriptor #borg on TikTok. METHODS: We identified highly viewed TikTok videos with the #borg hashtag (n = 103) and conducted a content analysis, capturing viewer engagement ('likes', shares, comments), techniques used, characteristics of featured individuals, and the portrayal of alcohol and risky drinking behaviours. RESULTS: Alcohol was visible in three quarters of the videos analysed (n = 78, average amount of alcohol present 865 mL per borg) and consumed in one third of the videos (n = 34). One quarter of videos (n = 25) promoted alleged benefits of borg consumption compared to other alcohol products or approaches to drinking, yet only nine videos included a warning about potential harms. CONCLUSIONS: The borg trend on TikTok may encourage risky drinking, by portraying it in a style that younger viewers are likely to see as fun and entertaining. SO WHAT?: We were able to gain a better understanding of how this potentially health harming activity is represented on a social media platform that is popular with young people. The speedy dissemination of this trend highlights the need to monitor, investigate and counter emerging trends. Concurrently, there is an urgent need for content restrictions to limit the visibility and promotion of risky alcohol consumption on TikTok.

An investigation of Australian midwifery curricula for obesity management and health behaviour change training.

INTRODUCTION: Fifty percent of Australian women enter pregnancy overweight or obese. Unfortunately, few women receive weight management advice from health professionals during pregnancy. The aim of this study was to investigate current midwifery curricula from Australian universities to identify strengths and deficits in the teaching of preconception and antenatal weight management. METHODS: Midwifery courses from 20 universities were identified. Of the 568 units taught at these universities, 252 course outlines were obtained. Data were coded using the qualitative analysis technique of Framework Analysis for the following main themes: 1) the effect of weight, diet and physical activity on health outcomes for women who are pregnant or planning a pregnancy; 2) weight management advice in any population; and 3) health behaviour change techniques in any context. RESULTS: Analysis revealed a variety of teaching methods and skills training that emphasised the importance of clinical judgement and autonomous clinical practice, in conjunction with critical enquiry and sourcing reputable evidence. There was little evidence, however, that weight management advice was taught explicitly to midwifery students in the curricula. DISCUSSION: A greater emphasis on skilling midwifery students to address weight gain during pregnancy, and behavioural techniques to achieve this, is required.

Preconception and antenatal knowledge and beliefs about gestational weight gain.

BACKGROUND: Prevention of excessive gestational weight gain during pregnancy is difficult; targeting women before pregnancy may be more effective. AIMS: In order to generate knowledge that may influence the development of effective interventions to promote healthy weight in reproductive-aged women, this study aimed to explore knowledge and belief formation regarding gestational weight gain for preconception and pregnant women. MATERIALS AND METHODS: Women ≥18 years (preconception n = 265; pregnant women at 16 weeks gestation n = 271) completed questionnaires assessing knowledge and beliefs about gestational weight gain. Responses were categorised according to the 2009 Institute of Medicine gestational weight gain recommendations. RESULTS: Preconception women exhibited poorer gestational weight gain knowledge than pregnant women, yet only half of pregnant women reported accurate gestational weight gain knowledge within the Institute of Medicine recommendations. Beliefs about gestational weight gain were also inaccurate for both preconception and pregnant women, with 34.1% of pregnant and 44.6% of preconception women expecting to gain less than recommendations. Gestational weight gain knowledge accounted for about half of the variance in gestational weight gain beliefs. CONCLUSIONS: Overall, the large inaccuracies in gestational weight gain knowledge and beliefs reported by both preconception and pregnant women suggest significant gaps in dissemination of gestational weight gain advice throughout the reproductive life phase. Knowledge is an important part of belief formation that can lead to appropriate weight gain. Hence, health professionals and policy makers should actively pursue opportunities to improve gestational weight gain knowledge in reproductive-aged women.

Student midwives' intention to deliver weight management interventions: A theory of planned behaviour & self-determination theory approach.

OBJECTIVES: Overweight and obesity during pregnancy is a risk to the health of mother and child. Midwives can modify this key risk factor by providing weight management interventions to women before and during pregnancy. This study investigated social cognitive determinants of pre-clinical student midwives' intention to provide weight management intervention in preconception and antenatal clinical contexts. Social cognitive determinants from the theory of planned behaviour (attitudes, subjective norms, perceived behavioural control) and self-determination theory (autonomous motivation) were used to predict pre-clinical students' intentions once they enter practice. METHOD: The sample was 183 female pre-clinical student midwives from 17 Australian universities (age range = 18-54 years). Participants received a cross-sectional questionnaire that measured demographic items, attitudes, subjective norms, perceived behavioural control and autonomous motivation towards providing weight management intervention at two different stages of pregnancy - preconception and antenatal. RESULTS: Attitudes, subjective norms, and perceived behavioural control accounted for 56% of intention to provide weight management interventions to women planning pregnancy; however, the addition of autonomous motivation was non-significant. In contrast, attitudes and subjective norms (but not perceived behavioural control) accounted for 39% of intention to provide weight management interventions to women during pregnancy. Furthermore, the addition of autonomous motivation to the model was significant and accounted for an additional 3.1% of variance being explained. IMPLICATIONS AND CONCLUSIONS: Curriculum changes that support and increase pre-clinical student midwives' intention should focus on these specific correlates of intention in order to foster long term changes in clinical practice. Changes to the education and training of midwives should be carefully considered to understand their impact on these important determinants of intention to engage in this critical clinical skill.

The associations between depressive and anxiety symptoms, body image, and weight in the first year postpartum: a rapid systematic review.

OBJECTIVE: The aim of this study was to conduct a rapid systematic review of the evidence of associations between postpartum depressive symptoms, anxiety symptoms, body image and weight status in the first 12 months post birth. BACKGROUND: The postpartum period places the mother and infant at risk of a number of negative health outcomes. Mental health conditions such as depression and anxiety are common in the postpartum, as are poor body image and excessive weight retention as women adjust to their post pregnancy body. However, the associations between body image, weight status and psychological distress are not currently well understood. METHODS: Articles in English, published between 2006 and 2017, involving singleton pregnancies of normally developing infants and maternal depression or anxiety were eligible for this systematic review. RESULTS: From the total of 1805 articles located, 12 were identified as relevant and were subsequently reviewed in full. In the nine studies of depressive symptoms, body image or weight status, four found a significant relationship. Significant associations were not found in the three studies investigating postpartum anxiety symptoms, body image or weight. Body dissatisfaction was associated significantly with poorer postpartum weight status in all nine studies. CONCLUSIONS: Further research is needed to determine the nature of the relationships between body image, weight status and depressive and anxiety symptoms across the first year after birth. This information will assist health professionals to promote healthy lifestyle behaviours in the postpartum, as well as inform clinical interventions that target behaviour change to prevent the worsening of these issues and related negative outcomes.

Weight in the First Year of Life: Associations with Maternal Prepregnancy Body Mass Index and Gestational Weight Gain-Findings from a Longitudinal Pregnancy Cohort.

Objective To investigate the obesogenic influence of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) on infant weight at birth and 12 months postpartum in an Australian general population sample. Methods Data on 1,305 pregnant women were collected on prepregnancy BMI and GWG through maternal interview, on infant weight at birth through hospital records, and on infant weight 12 months postbirth through direct measurement. Relationships between prepregnancy, gestational weight exposures, and infant weight outcomes were assessed with and without adjustment for potential confounding. Results We observed a 14 to 24 g increase in infant birth weight for every 1 kg increase in maternal weight (infant birth weight: ß(BMI) = 0.014, p < 0.000; ß(GWG) = 0.012, p < 0.000; and 12 months: ß(BMI) = 0.018, p < 0.000; ß(GWG) = 0.024, p < 0.000). Effects remained after adjustment for potential confounders (infant birth weight: ß(BMI) = 0.014, p < 0.000; ß(GWG) = 0.012, p < 0.001; and 12 months: ß(BMI)= 0.017, p ≤ 0.033; ß(GWG) = 0.023, p = 0.001). However, the effects observed were small, and there was no evidence that GWG mediated relationships between preconception BMI and infant weight. Conclusion In a general population sample, there is a significant but not substantial observed relationship between maternal prepregnancy BMI and GWG and infant weight outcomes, suggesting a minor role for these factors at a population level.

Lifestyle intervention to prevent obesity during pregnancy: Implications and recommendations for research and implementation.

Maternal obesity and excessive gestational weight gain (GWG) are significant contributors to the global obesity epidemic. However, isolated lifestyle interventions to address this in pregnancy appear to have only modest benefit and responses can be variable. This paper aims to address the question of why the success of lifestyle interventions to prevent excessive GWG is suboptimal and variable. We suggest that there are inherent barriers to lifestyle change within pregnancy as a life stage, including the short window available for habit formation; the choice for women not to prioritise their weight; competing demands including physiological, financial, relationship, and social situations; and lack of self-efficacy among healthcare professionals on this topic. In order to address this problem, we propose that just like all successful public health approaches seeking to change behaviour, individual lifestyle interventions must be provided in the context of a supportive environment that enables, incentivises and rewards healthy changes. Future research should focus on a systems approach that integrates the needs of individuals with the context within which they exist. Borrowing from the social marketing principle of 'audience segmentation', we also need to truly understand the needs of individuals to design appropriately tailored interventions. This approach should also be applied to the preconception period for comprehensive prevention approaches. Additionally, relevant policy needs to reflect the changing evidence-based climate. Interventions in the clinical setting need to be integrally linked to multipronged obesity prevention efforts in the community, so that healthy weight goals are reinforced throughout the system.

Preconception weight management: an untapped area of women's health.

The aim of this study was to identify barriers to providing preconception weight management. Twenty health professionals participated in a semistructured phone interview regarding their beliefs on perceived barriers to providing preconception weight management. The interviews were recorded, transcribed verbatim and examined using thematic analysis to extract the key themes. Two themes were identified from the interviews: (1) barriers hindering women from accessing preconception weight management interventions (i.e. women's lack of awareness regarding the importance of preconception weight, and not being provided with weight management information or interventions by health professionals); and (2) barriers preventing health professionals from providing preconception weight management (i.e. an absence of implementation resources for preconception weight management, limited access to women of childbearing age who plan to conceive, and a high percentage of pregnancies being unplanned). There are significant client- and heath professional-based barriers to implementing preconception weight management. To begin to address these barriers, developing policy and preconception weight management programs based on evidence collected via a needs assessment, quantitative or mixed-method designs may be of benefit. Furthermore, these barriers are likely contributing to the paucity in research into preconception weight management services.

Mutually Responsive Orientation: A novel observational assessment of mother-child mealtime interactions.

Mother-child mealtime interactions during preschool years is an important but overlooked factor when evaluating the influence of parent-child relationships on child eating and weight. This paper describes the validation of the Mutually Responsive Orientation (MRO) coding system adapted for assessing parent-child interactions during food preparation and consumption situations. Home-based mealtimes of 94 mothers and their children (3.03 ± 0.75 years) were filmed at two time points, 12-months apart. Filmed dimensions of mutual mother-child responsiveness, shared positive affect, maternal control relating to food and child compliance were assessed. Objective BMI and maternal reports of parenting, feeding, child eating, diet and child temperament were also collected. Correlations, repeated measures ANOVAs and regressions were performed to examine the validity of MRO variables and their stability across both time points. Validation analysis showed the MRO coding system performed as expected: dyads with higher MRO scores expressed lower control/power assertion, lower child non-compliance, and greater committed compliance. The measure demonstrated sensitivity to specific contexts: maternal responsiveness, mother and child positive affect were higher during food consumption compared to food preparation. Coded dimensions were stable across time points, with the exception of decreases in maternal responsiveness in food consumption and child non-compliance in food preparation. MRO and maternal dimensions were correlated with maternally reported parenting and feeding measures. Maternal responsiveness (inversely) and child responsiveness (positively) were concurrently associated with child fussy eating, and child refusal was prospectively and inversely associated with child fussy eating. Findings suggest the adapted MRO coding system is a useful measure for examining observed parent-child mealtime interactions potentially implicated in preschoolers' eating and weight development.

Can a health coaching intervention delivered during pregnancy help prevent excessive gestational weight gain?

This study evaluated: (1) the efficacy of a health coaching (HC) intervention designed to prevent excessive gestational weight gain (GWG); and (2) whether there were improved psychological, motivational, and behavioural outcomes for women in the HC intervention compared to a "usual care" control group. In this quasi-experimental study, 267 pregnant women ≤18 weeks gestation were recruited between August 2011 and June 2013 from two hospital antenatal clinics in Melbourne, Australia. Intervention women received four individual HC and two group HC/educational sessions informed by theories of behaviour change. Women completed questionnaires assessing psychological, motivational and behavioural outcomes at 16-18 (baseline) and 33 (post-intervention) weeks gestation. Weight measures were collected. Compared to usual care, the intervention did not limit GWG or prevent excessive GWG. However, HC women reported greater use of active coping skills post-intervention. Despite lack of success of the HC intervention, given the risks associated with excessive weight gain in pregnancy, health professionals should continue to recommend appropriate GWG.

Psychological Health and Lifestyle Management Preconception and in Pregnancy.

Healthful lifestyles before and during pregnancy are important to facilitate healthy outcomes for mother and baby. For example, behaviors such as a sedentary lifestyle and consuming an energy-dense/nutrient-poor diet increase the risk of overweight/obesity before pregnancy and excessive weight gain during pregnancy, leading to adverse maternal and child health outcomes. Maternal psychopathology may be implicated in the development of suboptimal maternal lifestyle behaviors before and during pregnancy, perhaps through impacts on motivation. This article explores this notion using maternal obesity and excessive gestational weight gain as examples of the health impacts of psychological states. We suggest that factors such as psychological well-being, individual motivation for behavior change, and broader environmental influences that affect both individual and system-wide determinants all play important roles in promoting healthy lifestyles periconception and are key modifiable aspects for intervention designers to consider when trying to improve dietary behaviors and increase physical activity before and during pregnancy. In addition, implementing system-wide changes that impact positively on individual and environmental barriers to behavior change that are sustainable, measureable, and effective is required.

Psychosocial factors and excessive gestational weight gain: The effect of parity in an Australian cohort.

OBJECTIVES: psychosocial variables can be protective or risk factors for excessive gestational weight gain (GWG). Parity has also been associated with GWG; however, its effect on psychosocial risk factors for GWG is yet to be determined. The aim of this study was to investigate if, and how, psychosocial factors vary in their impact on the GWG of primiparous and multiparous women. DESIGN/PARTICIPANTS: pregnant women were recruited in 2011 via study advertisements placed in hospitals, online, in parenting magazines, and at baby and children's markets, resulting in a sample of 256 women (113 primiparous, 143 multiparous). Participants completed questionnaires at 16-18 weeks' gestation and their pregravid BMI was recorded. Final weight before delivery was measured and used to calculate GWG. FINDINGS: the findings revealed that primiparous women had significantly higher feelings of attractiveness (a facet of body attitude; p=0.01) than multiparous women. Hierarchical regressions revealed that in the overall sample, increased GWG was associated significantly with lower pre-pregnancy BMI (standardised coefficient ß=-0.39, p<0.001), higher anxiety symptoms (ß=0.25, p=0.004), and reduced self-efficacy to eat a healthy diet (ß=-0.20, p=0.02). Although higher GWG was predicted significantly by decreased feelings of strength and fitness for primiparous women (ß=-0.25, p=0.04) and higher anxiety was related significantly to greater GWG for multiparous women (ß=0.43, p<0.001), statistical comparison of the model across the two groups suggested the magnitude of these effects did not differ across groups (p>0.05). CONCLUSIONS/IMPLICATIONS FOR PRACTICE: the findings suggest that psychosocial screening and interventions by healthcare professionals may help to identify women who are at risk of excessive GWG, and there may be specific psychosocial factors that are more relevant for each parity group.

The Role of Parity in Gestational Weight Gain and Postpartum Weight Retention.

OBJECTIVES: Parity, excessive gestational weight gain (GWG), and postpartum weight retention (PPWR) have been identified as risk factors for maternal obesity. The aim of this study was to explore whether GWG and PPWR at 6 and 12 months after birth differed for primiparous and multiparous Australian women. METHODS: One hundred thirty-eight Australian women provided weight measures in early to mid pregnancy (M = 16.7 weeks, SD = 2.3), late pregnancy (M = 37.7 weeks, SD = 2.4), 6 months postpartum (M = 6.1 months, SD = 1.4), and 12 months postpartum (M = 12.6 months, SD = 0.7). Height, parity, and demographic information were also collected. Prepregnancy body mass index (BMI), total GWG, incidence of excessive GWG, as well as change in BMI and BMI category from prepregnancy to 6 and 12 months postpartum were computed. Differences between primiparous and multiparous women were compared using analysis of covariance (controlling for age, prepregnancy BMI, and GWG) and χ(2) test of independence. RESULTS: Seventy women (50.7%) were primiparous and 68 women (49.3%) were multiparous. Primiparous women were more likely to retain weight at 12 months postpartum than multiparous women (p = .021; Cohen's d = .24). This difference was not reflected when analyzing change in BMI categories from prepregnancy to the postpartum. CONCLUSIONS: Evidence for the role of parity in PPWR is inconclusive. Future research should consider the temporal development of PPWR in primiparous and multiparous women, leading to tailored care in the postpartum period to help women return to a healthy prepregnancy weight.

Classification tree analysis of postal questionnaire data to identify risk of excessive gestational weight gain.

OBJECTIVE: overweight/obese weight status during pregnancy increases risk of a range of adverse health outcomes for mother and child. Whereas identification of those who are overweight/obese pre-pregnancy and in early pregnancy is straightforward, prediction of who will experience excessive gestational weight gain (EGWG), and thus be at greater risk of becoming overweight or obese during pregnancy is more challenging. The present study sought to better identify those at risk of EGWG by exploring pre-pregnancy BMI as well as a range of psychosocial risk factors identified as risk factors in prior research. METHODS: 225 pregnant women completed self-reported via postal survey measures of height, weight, and psychosocial variables at 16-18 weeks gestation, and reported their weight again at 32-34 weeks to calculate GWG. Classification and regression tree analysis (CART) was used to find subgroups in the data with increased risk of EGWG based on their pre-pregnancy BMI and psychosocial risk factor scores at Time 1. FINDINGS: CART confirmed that self-reported BMI status was a strong predictor of EGWG risk for women who were overweight/obese pre-pregnancy. Normal weight women with low motivation to maintain a healthy diet and who reported lower levels of partner support were also at considerable risk of EGWG. IMPLICATIONS FOR PRACTICE: present findings offer support for inclusion of psychosocial measures (in addition to BMI) in early antenatal visits to detect risk of EGWG. However, these findings also underscore the need for further consideration of effect modifiers that place women at increased or decreased risk of EGWG. Proposed additional constructs are discussed to direct further theory-driven research.

Health coaching to prevent excessive gestational weight gain: A randomized-controlled trial.

OBJECTIVES: The objectives of this study were to evaluate the efficacy of a health coaching (HC) intervention designed to prevent excessive gestational weight gain (GWG), and promote positive psychosocial and motivational outcomes in comparison with an Education Alone (EA) group. DESIGN: Randomized-controlled trial. METHODS: Two hundred and sixty-one women who were <18 weeks pregnant consented to take part. Those allocated to the HC group received a tailored HC intervention delivered by a Health Coach, whilst those in the EA group attended two education sessions. Women completed measures, including motivation, psychosocial variables, sleep quality, and knowledge, beliefs and expectations concerning GWG, at 15 weeks of gestation (Time 1) and 33 weeks of gestation (Time 2). Post-birth data were also collected at 2 months post-partum (Time 3). RESULTS: There was no intervention effect in relation to weight gained during pregnancy, rate of excessive GWG or birth outcomes. The only differences between HC and EA women were higher readiness (b = 0.29, 95% CIs = 0.03-0.55, p < .05) and the importance to achieve a healthy GWG (b = 0.27, 95% CIs = 0.02-0.52, p < .05), improved sleep quality (b = -0.22, 95% CIs = -0.44 to -0.03, p < .05), and increased knowledge for an appropriate amount of GWG that would be best for their baby's health (b = -1.75, 95% CI = -3.26 to -0.24, p < .05) reported by the HC at Time 2. CONCLUSIONS: Whilst the HC intervention was not successful in preventing excessive GWG, several implications for the design of future GWG interventions were identified, including the burden of the intervention commitment and the use of weight monitoring. STATEMENT OF CONTRIBUTION: What is already known on the subject? Designing interventions to address gestational weight gain (GWG) continues to be a challenge. To date, health behaviour change factors have not been the focus of GWG interventions. What does this study add? Our health coaching (HC) intervention did not reduce GWG more so than education alone (EA). There was an intervention effect on readiness and importance to achieve healthy GWG. Yet there were no group differences regarding confidence to achieve healthy GWG post-intervention.

Psychosocial risk factors for excessive gestational weight gain: A systematic review.

BACKGROUND: Excessive weight gain during pregnancy can have adverse health outcomes for mother and infant throughout pregnancy. However, few studies have identified the psychosocial factors that contribute to women gaining excessive weight during pregnancy. AIM: To review the existing literature that explores the impact of psychosocial risk factors (psychological distress, body image dissatisfaction, social support, self-efficacy and self-esteem) on excessive gestational weight gain. METHODS: A systematic review of peer-reviewed English articles using Academic Search Complete, Cumulative Index to Nursing and Allied Health Literature, MEDLINE Complete, PsycINFO, Informit, Web of Science, and Scopus was conducted. Quantitative studies that investigated psychosocial factors of excessive GWG, published between 2000 and 2014 were included. Studies investigating mothers with a low risk of mental health issues and normally-developing foetuses were eligible for inclusion. From the total of 474 articles located, 12 articles were identified as relevant and were subsequently reviewed in full. FINDINGS: Significant associations were found between depression, body image dissatisfaction, and social support with excessive gestational weight gain. No significant relationships were reported between anxiety, stress, self-efficacy, or self-esteem and excessive gestational weight gain. CONCLUSION: The relationship between psychosocial factors and weight gain in pregnancy is complex; however depression, body dissatisfaction and social support appear to have a direct relationship with excessive gestational weight gain. Further research is needed to identify how screening for, and responding to, psychosocial risk factors for excessive gestational weight gain can be successfully incorporated into current antenatal care.

Understanding gestational weight gain: the role of weight-related expectations and knowledge.

BACKGROUND: Health behaviour theories acknowledge that beliefs, attitudes and knowledge contribute to health behaviours, yet the role of these cognitions in predicting weight gain during pregnancy has not been widely researched. AIMS: To explore and compare the predictive nature of gestational weight gain (GWG) expectations and knowledge on weight gain during pregnancy. MATERIALS AND METHODS: One hundred and sixty-six women were tracked during pregnancy. Participants provided information on prepregnancy weight, height, GWG expectations and knowledge at 16-18 weeks' gestation (Time 1). To calculate gestational weight gain, prepregnancy weight was subtracted from weight at 36 weeks' gestation (collected at Time 2). Gestational weight gain above the Institute of Medicine's GWG recommendations was classified as excessive. A hierarchical regression examined the predictive nature of GWG expectations for actual GWG. Chi-square significance tests determined whether the accuracy of GWG knowledge differed depending on GWG status and prepregnancy BMI category. RESULTS: GWG expectations were a significant predictor of weight gain during pregnancy. Women who experienced excessive GWG were more likely to overestimate the minimum amount of weight that they needed to gain to have a healthy baby. CONCLUSIONS: GWG expectations are predictive of actual GWG, and GWG knowledge among women is generally poor. In particular, overestimating of the minimum amount of weight to gain during pregnancy is associated with excessive GWG. As such, it may be beneficial to design interventions to prevent excessive GWG that targets these cognitions.

A longitudinal study of the effect of psychosocial factors on exclusive breastfeeding duration.

OBJECTIVE: to examine the effect of psychosocial factors on exclusive breastfeeding duration to six months postpartum DESIGN: longitudinal, prospective questionnaire based study. SETTING: participants were recruited from a publically funded antenatal clinic located in the western metropolitan region of Melbourne, Victoria, Australia and asked to complete questionnaires at three time points; 32 weeks pregnancy, two months postpartum and six months postpartum. PARTICIPANTS: the participants were 125 pregnant women aged 22-44 years. MEASUREMENTS AND FINDINGS: psychosocial variables such as breastfeeding self-efficacy, body attitude, psychological adjustment, attitude towards pregnancy, intention, confidence and motivation to exclusively breastfeed and importance of exclusive breastfeeding were assessed using a range of psychometrically validated tools. Exclusive breastfeeding behaviour up to six months postpartum was also measured. At 32 weeks gestation a woman's confidence to achieve exclusive breastfeeding was a direct predictor of exclusive breastfeeding duration to six months postpartum. At two months postpartum, psychological adjustment and breastfeeding self-efficacy were predictive of exclusive breastfeeding duration. Finally, at six months postpartum, psychological adjustment, breastfeeding self-efficacy, confidence to maintain and feeling fat were directly predictive of exclusive breastfeeding duration. KEY CONCLUSIONS: psychosocial factors are significantly predictive of exclusive breastfeeding duration. Self-efficacy, psychological adjustment, body image, motivation and confidence are all important psychosocial factors implicated in a woman's ability to maintain exclusive breastfeeding over time. IMPLICATIONS FOR PRACTICE: Individualised antenatal breastfeeding education and support may be strengthened by strategies that build a woman's confidence to exclusive breastfeeding. Implementing psychosocial supports and methods providing positive feedback that increase a woman's self-efficacy to exclusively breastfeed to six months are also important two months postpartum.

Relationships between mental health symptoms and body mass index in women with and without excessive weight gain during pregnancy.

OBJECTIVE: This study investigated the prospective relationships between mental health symptoms (depressive and anxiety symptoms) and body mass index (BMI) in women with and without excessive weight gain during pregnancy. The secondary aim was to examine whether mental health symptoms and BMI were predictive of one another. Two models were tested: the first depicted depressive or anxiety symptoms predicting BMI, and the second model depicted BMI predicting depressive or anxiety symptoms. DESIGN AND PARTICIPANTS: Women completed questionnaires at three time points throughout pregnancy, which comprised of the Depression, Anxiety and Stress Scale-21 and self-reported weight. Height and weight were also reported retrospectively at T1 to calculate pre-pregancy BMI category. To calculate total gestational weight gain (GWG), pre-pregnancy weight was substracted from weight at 36 weeks gestation. METHODS: 183 women were tracked during pregnancy; Time (T)1 (mean=16.50 weeks of gestation, SD=.92), T2 (mean=24.40 weeks of gestation, SD=.92), and T3 (mean=32.61 weeks gestation, SD=.88). The sample was divided into those for whom weight gain exceeded the guidelines for GWG (excessive gestational weight gain; EGWG), and those who for whom it did not. Multigroup path analyses compared the longitudinal relationships between depressive or anxiety symptoms and BMI during pregnancy for women with and without EGWG. FINDINGS: BMI did not predict depressive or anxiety symptoms. Depressive symptoms at T1, did however predict higher BMI at T2 for women without EGWG. Anxiety symptoms and BMI were not related, regardless of GWG status. CONCLUSION: These findings suggest that depressive symptoms may precede increased BMI during pregnancy in women who do not gain weight excessively. There may be longitudinal relationships between depressive symptoms and BMI during pregnancy; however, further research is required to identify the mechanisms that link these health outcomes and inform the focus of intervention design.

Preventing mental health problems in offspring by targeting dietary intake of pregnant women.

BACKGROUND: The concept of 'early life programming' considers the importance of very early environmental exposures throughout the gestational period on the subsequent health outcomes of offspring. The role of maternal dietary intake, specifically, has been highlighted after recent studies have shown maternal diet quality to predict mental health problems in offspring. Even in the pre-conception period, maternal nutrition can have permanent and sustained phenotypic consequences for offspring. DISCUSSION: Here, we consider these findings in the context of the primary prevention of mental disorders and argue that interventions that target maternal diet could be of significant value. SUMMARY: It is clear that, in order to reduce the burden of mental health issues across the lifespan, urgent action is required, particularly in the field of prevention. We thus call for the application and evaluation of targeted, primary prevention strategies that focus on dietary intake with the view to improve mental health outcomes of mothers and offspring during the postnatal period and beyond.
