Prevalence of food insecurity among caregivers of young children during the COVID-19 pandemic in Ireland.

Our objectives were to explore the prevalence of food insecurity in primary caregivers of young children in Ireland and to compare two tools for measuring food insecurity during the COVID-19 crisis. A cross-sectional online survey was conducted among caregivers of children aged <2 years in Ireland in May/June 2020. Relevant survey questions were closed-ended using two established tools for measuring food poverty/insecurity; the Irish Food Poverty Indicator and the Food Insecurity Experience Scale, developed by the Food and Agriculture Organization. Descriptive statistics were used to calculate the prevalence of food poverty/insecurity. To explore agreement in the classification of food insecurity by the Food Poverty Indicator and the Food Insecurity Experience Scale, Cohen's κ was used. Analyses are based on 716 participants; most had a 3rd-level education and were married or in a partnership. Per the food poverty index, Ireland's national measure of food poverty, 3.9% (n = 28) of our sample were experiencing food poverty. This rose to 10.5% (n = 75) experiencing food insecurity when using the Food Insecurity Experience Scale, which also measures worry/anxiety around access to food. There was low agreement between the tools, with 11.3% of the sample classified as food secure by one tool and food insecure by the other. Our current measure of food poverty in Ireland may not be sufficient to describe the food-access struggles or worry/anxiety about food access, experienced by the population, particularly during an emergency like COVID-19.

What makes a city 'breastfeeding-friendly'? A scoping review of indicators of a breastfeeding-friendly city.

A breastfeeding-friendly city is one where there is an enabling environment to support breastfeeding throughout the first 2 years or more of a child's life. Indicators of a breastfeeding-friendly city have yet to be identified. What are the indicators or criteria used to define breastfeeding friendliness in a geographic area such as a city and the settings within, which we have classified as community, healthcare and workplace? Three major databases and grey literature were searched. Records were screened to identify publications describing criteria such as indicators or descriptions of a breastfeeding-friendly setting, defined as 'criteria-sets'. These criteria-sets were then categorized and summarized by settings. The search up to 2 September 2021 found 119 criteria-sets from a range of settings: geographic locations (n = 33), community entities (n = 24), healthcare facilities (n = 28), workplaces (n = 28) and others (n = 6). Overall, 15 community, 22 healthcare and 9 workplace related criteria were extracted from the criteria-sets. Criteria that were consistently present in all settings were policy, training & education, skilled breastfeeding support and physical infrastructure. Some criteria-sets of geographic locations contained criteria only from a single setting (e.g., the presence of breastfeeding-friendly cafes). Criteria-sets were present for all settings as defined in this review, but few were actual indicators. Specifically, there were no existing indicators of a breastfeeding-friendly city. Several common components of the criteria-sets were identified, and these could be used in developing indicators of a breastfeeding-friendly city. Future studies should determine which of these are important and how each can be measured.

The underlying role of food guilt in adolescent food choice: A potential conceptual model for adolescent food choice negotiations under circumstances of conscious internal conflict.

Food choice decisions are challenging to conceptualise, and literature is lacking specific to adolescent food choice decisions. Understanding adolescent nutrition and food choice is becoming increasingly important. This research aims to understand what influences the food choices of Irish adolescents, and the mental negotiations occurring in food-based decisions. Additionally, it aims to develop a holistic conceptual model of food choice, specific to adolescents. A qualitative study was conducted in N = 47 Irish adolescents, via focus group discussions using vignettes to introduce discussion topics around food and eating habits. Data were analysed using reflexive thematic analysis, involving both semantic and latent analysis. Thirteen distinct factors related to adolescent food choices were discussed, forming one main theme and three inter-linking subthemes. The main theme relates to food choice being multi-factorial in nature, needing a balance of priorities through internal negotiations for food choice with the aim of reducing food guilt. This can change depending on the social setting. Social concerns and food guilt appear to play a strong role in adolescent food choice, with adolescents feeling guilty for eating unhealthy food, wasting food, or spending/wasting money on food. A conceptual model for food choice in adolescents was developed, named a "Food Choice Funnel", incorporating a specific "Food Guilt Matrix". While we should encourage healthy eating and a healthy lifestyle, it is important to understand the value placed on the social component to eating among adolescents, since they have increasing social interactions and occasions where choosing health-promoting foods may be more challenging. Healthy eating messages should be designed in a balanced manner to support healthy growth and development, while limiting the potential to induce feelings of guilt among adolescents.

Gender considerations for supportive supervision in humanitarian contexts: A qualitative study.

Supportive supervision has been shown to improve mental health outcomes and job retention for mental health and psychosocial support (MHPSS) workers in humanitarian contexts. However, the impact of gender on supervision practices has been poorly evaluated and documented in international guidelines to date. To address this gap, qualitative interviews were conducted with 12 MHPSS staff working in diverse humanitarian contexts to identify key gender considerations in supportive supervision. Results show that gender in supervision is influenced by the context of MHPSS work; with culture, religion and gender roles identified as key elements. Participants discuss recruitment mechanisms, highlighting the unequal gender distribution and inequitable opportunities within MHPSS programming. The importance of addressing power dynamics impacted by gender and of ensuring the safety of women within supervision is also highlighted. Finally, participants discuss the gender differences across the various supervisory formats. Altogether, results indicate that gender has the potential to influence supportive supervision within MHPSS, and it is recommended that international guidelines account for nuances of gender in supportive supervision within humanitarian contexts.

Parents' experiences of infant and young child feeding during the COVID-19 pandemic in Ireland.

OBJECTIVE: The WHO has urged member states to develop preparedness plans for infant and young child feeding (IYCF) during emergencies. Ireland has no such plan. We aimed to identify the needs of caregivers in Ireland with regards IYCF during the COVID-19 pandemic. DESIGN: Online survey conducted in May-June 2020. SETTING: Ireland, during the first period of severely restricted movement due to COVID-19 (lockdown). PARTICIPANTS: Respondents (n 745) were primary caregivers of a child under 2 years; they were primarily well educated and likely of higher socio-economic status. RESULTS: Among those who breastfed, being unable to access breast-feeding support groups and being unable to access in-person, one-to-one breast-feeding assistance were the biggest challenges reported. Nearly three quarters of those who had their babies during lockdown reported these challenges: 72·8 % and 68·8 %, respectively. For those using formula, the main challenges were structural in nature; approximately two-thirds of those who had their baby prior to lockdown feared there would be formula shortages and a third were unable to purchase formula due to shortages. CONCLUSIONS: Regardless of how their babies were fed, parents in Ireland experienced multiple challenges with infant feeding during the COVID-19 crisis. Breast-feeding should be protected, supported and promoted, particularly during an infectious disease pandemic. Additionally, assurances around supply of infant formula could reduce parental stress during a pandemic or emergency. An IYCF in emergencies plan would clearly set out how we could best support and protect the nutrition of the most vulnerable members of our population.

A qualitative analysis of women's postnatal experiences of breastfeeding supports during the perinatal period in Ireland.

Ireland has among the lowest rates of breastfeeding worldwide. Despite policies to support breastfeeding, breastfeeding initiation and exclusivity remain low in Ireland. Greater knowledge about support received in the maternity unit may-in part-shed light on why this is so. Our aim was to analyse women's experiences of the breastfeeding supports available in the early postnatal period in Ireland. We conducted an analysis of an open-ended question on a cross-sectional survey about breastfeeding support conducted in the Republic of Ireland in 2022. Participants were asked to provide comments about the breastfeeding support they received in the maternity unit or during your home birth. Data were analysed using Braun and Clarke's six-step Thematic Analysis Framework. There were 5,412 unique responses to the survey and 2,264 responses to the question of interest. Two themes were generated from the data: (i) 'Breastfeeding support in theory but not in practice.' Although breastfeeding was promoted by healthcare professionals antenatally, breastfeeding challenges were rarely mentioned. Participants then felt unsupported in overcoming challenges postnatally. (ii) 'Support was either inaccessible due to lack of staff/time, inadequate; i.e., unhelpful or non-specific, and/or physically inappropriate.' Most participants described receiving supports that were less than optimal in aiding them to establish breastfeeding. While many described difficulties in accessing supports, others found support to be 'non-specific,' 'rushed' and sometimes 'rough.' A lack of knowledge, time and support from healthcare professionals was frequently described, which was often recognised as a failing of the healthcare system. Women require practical, informative, and specific breastfeeding support. Barriers such as lack of time and trained staff in the maternity unit need to be addressed.

Determining the food choice motivations of Irish teens and their association with dietary intakes, using the Food Choice Questionnaire.

During adolescence, teens start making their own food choices. While health and nutrition are important, practical and social concerns are also influential. This study aims to determine factors that motivate the food choices of Irish teens (using Food Choice Questionnaire), using data from the National Teens' Food Survey II (N = 428, 50% male, 13-18 years), and to identify how these motivations relate to dietary intakes (4-day semi-weighed food diaries). Data analysis used PCA to determine the food choice motivation subscales, and correlation and comparative statistical tests (t-test, ANOVA). Eight motivating factors were identified for Irish teens: Sensory Appeal, Price & Availability, Health & Natural Content, Familiarity, Ease of Preparation, Mood, Weight Control, and Ethical Concerns. Health and practical aspects to food choice (Price, Availability, Ease of Preparation) are important for teens, but taste (Sensory Appeal) remains a key influence. Food choice motivations vary by sex and by age, BMI status and weight perception, where girls were more motivated by health, weight control, mood and ethical concerns, and older teens were more influenced by mood and ease of preparation. Both those classified as overweight and those who perceived they were overweight were motivated more by weight control and mood for their food choices, whereas those who perceived their weight to be correct placed more importance on health and natural content. Those motivated by weight control had lower energy and higher protein intakes, and those motivated by health and natural content had more health promoting behaviours, with higher physical activity, lower screen time, and higher protein intakes. Understanding the motivations of teens' food choice can help understand why they struggle to meet dietary recommendations, and help to develop more effective health promotion messages by capitalising on the key motivations in the population.

Childhood obesity: overcoming the fear of having healthier weight conversations with families.

Introduction Clinicians may find raising the issue of weight with patients or carers and having healthier lifestyle conversations uncomfortable, out of fear or experience of causing offence. A two-cycle audit was completed in a specialist paediatric dental service to ascertain whether healthier weight conversations were being had with patients and their carers.Materials and methods The inclusion criteria for the audit were paediatric patients who were having a general anaesthetic assessment for dental extractions as a result of dental caries. A gold standard was set that all patients having a general anaesthetic assessment should have their body mass index (BMI) calculated and healthier weight conversations should be had with patients and carers and families signposted for further support when necessary.Results Results for the first cycle found that only 7% of patients had their BMI recorded and there was no record of healthier weight conversations for any patient. After the results of the first cycle were shared and ways in which to have a helpful healthy weight conversation discussed, a second cycle was carried out. A significant improvement was made, with clinicians calculating the BMI for 65% of the patients and a healthier weight conversation being had when necessary.Discussion Many of the clinicians voiced that as calculating a BMI and having healthier weight conversations is not something that they had previously routinely done, they often forget to do this. Others stated that they felt uncomfortable bringing up the topic in a way that wouldn't offend the patient or parent, so avoided doing so.Conclusions As a result of the audit, it was strongly encouraged that all clinicians continue to calculate BMI as it was found to be a useful tool for introducing healthier weight conversations when necessary. The subject of healthier weight needs to be acknowledged in the dental setting and discussed with families in a non-judgemental and sensitive way. This paper aims to guide clinicians in how to sensitively broach this subject with children and carers and when and where to signpost if extra support is needed.

Considerations for health and food choice in adolescents.

The aim of this review is to summarise the common barriers and motivations for healthy food choice among adolescents, with a specific focus on the Irish context where available. It will also discuss other concerns adolescents have, which may influence their food choices and eating habits. Adolescence represents a period of rapid physical, mental and social development, and many health-related habits developed during adolescence tend to persist into adulthood, making the teenage years an optimal time to encourage healthy eating and health-promoting behaviours. Adolescents are concerned about the health impact of their diet, but their understanding of health is often seen in the context of their physical appearance or body image. Body image concerns are prevalent in adolescents, and this can affect their food choices. Taste, price and convenience are commonly noted factors influencing adolescents' food choices, and as they grow, their level of independence increases and spending more time with their peers means that social desirability and social norms about food become increasingly important factors in adolescent food choice. However, their limited autonomy means their supporting food environment also plays an important role. When developing more targeted interventions in adolescent populations, information on adolescent nutrition needs, their concerns for health and body image, and the barriers and motivations for healthy eating and food choice should be considered. Such a holistic approach should help support healthy eating and the prevention of overweight and obesity in the population, whilst also supporting a healthy relationship with food and their bodies.

Use of non-invasive ventilation in motor neuron disease - a retrospective cohort analysis.

Motor neuron disease (MND) is a neurodegenerative disorder which leads to progressive muscle weakness including respiratory muscle decline. The introduction of non-invasive ventilation (NIV) has been shown to improve quality of life, survival and slow the rate of pulmonary function decline. A retrospective chart analysis of patients who attended the MND clinic from 2014 to 2019 at a tertiary-referral, academic, teaching hospital was carried out to evaluate if NIV and greater compliance with NIV was associated with improved survival. 111 patients were included. The mean age at diagnosis was 63.8 years and 61.3% were males. 66.7% of our cohort used NIV and of this 66.7%, 44.1% were compliant. There was a significantly longer survival in those who used NIV (p = 0.002) and in those who used NIV optimally (p = 0.02) when both groups were compared to those who did not use NIV. In the bulbar MND group those who were compliant with NIV survived longer than who those who did not use NIV (p = 0.001). We found a significantly longer survival with the use of NIV, the use of NIV optimally and with use of NIV in those with bulbar onset MND compared to those who did not use NIV.

Association between attendance at a specialist palliative care day unit and improvement in patient symptoms and quality of life.

BACKGROUND: Specialist palliative day care is an area of palliative care which has a notable scarcity of research. Evidence is needed on the role of palliative day care to improve patients' quality of life and symptom management, while recognising the different patient cohorts that use the service. AIM: To determine the symptoms and quality of life of the patient cohort that are affected by the completion of a full therapeutic cycle (8 to 9 weeks) at a specialist palliative care day unit (SPCDU). METHOD: A retrospective cohort study was carried out from January 2016 to December 2017. Patient related outcome measures (PROMs) were collected as part of routine clinical paperwork at admission and discharge, and these were used to determine symptoms and quality of life pre-attendance and on completion of an 8 to 9 week therapeutic cycle at the SPCDU. RESULTS: Descriptive analysis demonstrated improvement across the many symptoms that were analysed. Quality of life analysis also established improvement. Statistically significant difference was achieved in several areas. Total physical symptoms (p value=.009) confirmed the positive impact attendance at SPCDU has on physical symptoms. Specific symptoms which displayed a statistically significant difference included: poor appetite (p value=.002), weakness (p value=.03) and the anxiety felt by family/friends (p value=.029). The quality of a patient's life also displayed statistically significant difference (p value=.000). CONCLUSION: This study demonstrates that attendance at a SPCDU may positively impact a patients' symptoms and quality of life. A more uniform national approach to specialist palliative day care delivery, alongside multi-setting research, may further bolster the image of palliative day care. This will improve referrals to and occupancy of SPDCUs and benefit the palliative patient in the community.

Eating behaviour styles in Irish teens: a cross-sectional study.

OBJECTIVES: To describe the eating behaviour styles of Irish teens and to explore the relationships between demographic factors, BMI and dietary intake and these eating behaviour styles. DESIGN: Cross-sectional data from the Irish National Teens' Food Survey (2005-2006). The Dutch Eating Behaviour Questionnaire assessed three eating behaviour styles in teens: restrained, emotional and external eating. Data were stratified by sex and age groups. SETTING: The Republic of Ireland. PARTICIPANTS: Nationally representative sample of teens aged 13-17 years (n 441). RESULTS: The highest scoring eating behaviour style was external eating (2·83 external v. 1·79 restraint and 1·84 emotional). Girls scored higher than boys on all three scales (Restraint: 2·04 v. 1·56, P < 0·001, Emotional: 2·15 v. 1·55, P < 0·001 and External: 2·91 v. 2·76, P = 0·03), and older teens scored higher than younger teens on the Emotional (1·97 v. 1·67, P < 0·001) and External scales (2·91 v. 2·72, P = 0·01). Teens classified as overweight/obese scored higher than those classified as normal weight on the Restraint scale (2·15 v. 1·71, P < 0·001) and lower on the External scale (2·67 v. 2·87, P < 0·03). Daily energy intake was negatively correlated with the Restraint (r -0·343, P < 0·001) and Emotional scales (r -0·137, P = 0·004) and positively correlated with the External scale (r 0·110, P = 0·02). CONCLUSIONS: External eating is the predominant eating behaviour style among Irish teens, but sex, age, BMI and dietary differences exist for each eating behaviour style. Including measures of eating behaviour styles into future dietary research could help understand both how and why as well as what people eat.

The impact of COVID-19 on paediatric dental services and tips for patient management.

Managing paediatric patients in primary dental care while awaiting treatment by the specialist paediatric dental services can be tricky. COVID-19 has had a significant impact on dental services meaning wait times to be seen by a paediatric dental service may have been delayed. This article will discuss the management of paediatric patients in primary dental care and provide an update on some of the latest techniques in paediatric dentistry. It also covers tips that can be employed in the primary dental care setting such as the use of tooth mousse and silver diamine fluoride.

A Qualitative Exploration of the Attitudes and Experiences of Polish Breastfeeding Mothers in Ireland.

BACKGROUND: Breastfeeding rates in Ireland are among the lowest in the world. Improving the prevalence of breastfeeding is an objective of the Irish Health Service Executive, with the recognition that this would improve public health. Polish people represent the largest immigrant group in Ireland, and Polish women are more likely to initiate breastfeeding than Irish women. RESEARCH AIMS: This study had two aims: (1) to describe the breastfeeding experiences and attitudes among Polish mothers living in Ireland, and (2) to explore similarities and differences in infant feeding experiences, attitudes, and beliefs among Polish and Irish women, as perceived by Polish women. METHODS: Semi-structured interviews were conducted in Polish with Polish mothers (N = 16) who had lived in Ireland for 10 years or less. Interviews were audio recorded, transcribed, and translated into English. Data were analyzed using qualitative thematic analysis. Coding was a cyclical process; codes were amended and refined through iterative reading of the transcripts. Themes were developed through categorization of codes and via in-depth discussion between two analysts. RESULTS: Three major themes were developed after analyzing the data. First, there is no universal correct way to provide support for infant feeding; women would like individualized support based on their infant-feeding decisions. Second, breastfeeding is an inherent part of Polish culture and formula feeding is part of Irish culture. Finally, the Irish social environment is supportive of breastfeeding and breastfeeding in public is acceptable in Ireland. CONCLUSIONS: Although the Irish social environment is supportive of breastfeeding, the infant-formula culture is a barrier to breastfeeding. Future research should explore ways to change societal attitudes towards breastfeeding in Ireland.

Dietitians supporting breastfeeding: a survey of education, skills, knowledge and attitudes.

BACKGROUND: Breastfeeding rates in Ireland are among the lowest in the world; thus, it is important to understand what knowledge and skills exist and what are the education needs of dietitians. There has been no Irish research on dietitians' perception of their role in promoting, protecting and supporting breastfeeding. AIMS: The aim of this study was to explore the breastfeeding-related education that dietitians participated in, their breastfeeding-related skills, knowledge and attitudes towards breastfeeding. METHODS: An e-survey was conducted among members of the Irish Nutrition and Dietetic Institute. RESULTS: Fifty-nine percent of the 181 respondents received education or training on breastfeeding since qualifying with a trend of more training time on general breastfeeding knowledge and less time on clinical issues. There were lower confidence in skills, and role expectations related to clinical practice and clinical skills were perceived as required by only a few dietitians in specific roles. Personal breastfeeding experience was associated with greater confidence in their breastfeeding-related skills and a greater likiehood of reporting positive attitudes. The main source of information about breastfeeding was own reading or experience. Most respondents (64%) felt that their practice would benefit from additional training. The most frequently reported barriers to providing breastfeeding-related care were "I lack the skill", "I lack the confidence", and "I lack the knowledge to provide assistance with breastfeeding". CONCLUSIONS: Further examination of the role of the dietitian and the establishment of expected competencies would provide a clear framework for future training and education of dietitians towards increasing breastfeeding prevalence in Ireland.

Cost-effectiveness of a mobile health-supported lifestyle intervention for pregnant women with an elevated body mass index.

OBJECTIVE: To assess the cost-effectiveness of a mobile health-supported lifestyle intervention compared with usual care. METHODS: We conducted a cost-effectiveness analysis from the perspective of the publicly-funded health care system. We estimated costs associated with the intervention and health care utilisation from first antenatal care appointment through delivery. We used bootstrap methods to quantify the uncertainty around cost-effectiveness estimates. Health outcomes assessed in this analysis were gestational weight gain (GWG; kg), incidence of excessive GWG, quality-adjusted life years (QALYs), and incidence of large-for-gestational-age (LGA). Incremental cost-effectiveness ratios (ICERs) were calculated as cost per QALY gained, cost per kg of GWG avoided, cost per case of excessive GWG averted, and cost per case of LGA averted. RESULTS: Total mean cost including intervention and health care utilisation was €3745 in the intervention group and €3471 in the control group (mean difference €274, P = 0.08). The ICER was €2914 per QALY gained. Assuming a ceiling ratio of €45,000, the probability that the intervention was cost-effective based on QALYs was 79%. Cost per kg of GWG avoided was €209. The cost-effectiveness acceptability curve (CEAC) for kg of GWG avoided reached a confidence level of 95% at €905, indicating that if one is willing to pay a maximum of an additional €905 per kg of GWG avoided, there is a 95% probability that the intervention is cost-effective. Costs per case of excessive GWG averted and case of LGA averted were €2117 and €5911, respectively. The CEAC for case of excessive GWG averted and for case of LGA averted reached a confidence level of 95% at €7090 and €25,737, respectively. CONCLUSIONS: Results suggest that a mobile-health lifestyle intervention could be cost-effective; however, a better understanding of the short- and long-term costs of LGA and excessive GWG is necessary to confirm the results.

An observational analysis of meal patterns in overweight and obese pregnancy: exploring meal pattern behaviours and the association with maternal and fetal health measures.

BACKGROUND: Nutrient intakes are known to be poorer among pregnant women with raised body mass index (BMI) than those with a healthy BMI. While meal patterns have the potential to influence obstetric, metabolic and anthropometric measures for mother and infant, limited data exists regarding meal patterns among pregnant women with raised BMI. AIM: To identify categories of meal patterns among pregnant women with overweight and obesity and determine whether patterns change with advancing gestation. To determine if maternal meal patterns are associated with dietary intakes and pregnancy outcomes. METHODS: Prospective, observational analysis of pregnant women (n = 143) (BMI 25-39.9 kg/m2). Meal pattern data were analysed from 3-day food diaries at 16 and 28 weeks' gestation. Outcomes include maternal blood glucose, insulin resistance, gestational diabetes, gestational weight gain and infant anthropometry. RESULTS: Three meal pattern categories were identified: 'main meal dominant' (3 main eating occasions + 0-3 snacks), 'large meal dominant' (≤ 2 main eating occasions + < 2 snacks), and 'snack dominant' (3 main eating occasions + > 3 snacks and ≤ 2 main + ≥ 2 snacks). A main meal-dominant pattern prevailed at 16 weeks' (85.3%) and a snack-dominant pattern at 28 weeks' (68.5%). Dietary glycaemic index was lower among the main meal versus large meal-dominant pattern at 28 weeks (P = 0.018). Infant birth weight (kg) and macrosomia were highest among participants with a large meal-dominant pattern at 28 weeks (P = 0.030 and P = 0.008, respectively). CONCLUSION: Women with raised BMI changed eating patterns as pregnancy progressed, moving from main meal-dominant to snack-dominant patterns. Large meal-dominant meal patterns in later pregnancy were associated with higher glycaemic index and greater prevalence of macrosomia.

Comparing Alternative Breast Milk Feeding Questions to U.S. Breastfeeding Surveillance Questions.

Background: Most mothers in the United States express their milk, which is then bottle fed to their infants. The National Immunization Survey (NIS), used to report national breastfeeding prevalence, asks about infant breast milk consumption, regardless of whether it is consumed at the mother's breast or from a bottle. The NIS data are often erroneously interpreted, however, to mean prevalence of at-the-breast feeding. We hypothesized that over half of infants classified as breastfed at 3, 6, and 12 months by the NIS questions would also be consuming expressed breast milk. Materials and Methods: A convenience sample of 456 mothers of infants 19-35 months of age recruited through ResearchMatch.org completed an online infant-feeding questionnaire. The questionnaire included both the NIS questions and more-detailed questions about feeding mode, distinguishing between at-the-breast and bottle. Results: Based on responses of our sample to the NIS questions, it could be interpreted that 74%, 64%, and 39% of mother-infant dyads were at-the-breast feeding at 3, 6, and 12 months, respectively. However, at each time point, most infants consumed at least some breast milk from a bottle. As infants got older, the proportion of breast milk consumed from a bottle increased. Conclusions: In this U.S. sample, the predominant breast milk feeding style involves both at-the-breast and expressed breast milk feeding. Future research and national surveillance should consider including separate measures of maternal breast milk expression and infant consumption of expressed breast milk to enable meaningful exploration of maternal and infant outcomes associated with these asynchronous behaviors.

Nutrition, Behavior Change and Physical Activity Outcomes From the PEARS RCT-An mHealth-Supported, Lifestyle Intervention Among Pregnant Women With Overweight and Obesity.

Background: Diet quality and physical activity positively impact pregnancy outcomes among women with obesity, but successful lifestyle interventions require intense clinician time. We aimed to investigate the impact of a behavioral-lifestyle intervention (PEARS) supported by a smartphone app among pregnant women with overweight and obesity, on nutrient intake, behavioral stage-of-change and physical activity. Methods: Pregnant women (BMI 25-39.9 kg/m2, measured, n = 565) were randomized at 15.6 weeks' gestation to the intervention (n = 278), or a control group (n = 287) (ISRCTN29316280). The intervention was grounded in behavior-change theory. Participants received nutrition (low glycaemic index and healthy eating) and exercise advice, a smartphone app and fortnightly emails. The control group received usual care which does not include dietary advice. At baseline and 28 weeks' gestation, dietary data were obtained through 3-day food diaries (n = 290 matched), and stage-of-change and physical activity data were self-reported. App usage data were collected. Results: There were no differences between the groups at baseline. Compared with the control group, the intervention group had improved dietary intakes post-intervention with; lower glycaemic index (MD -1.75); free sugars (%TE) (MD -0.98); fat (%TE) (MD -1.80); and sodium (mg) (MD -183.49). Physical activity (MET-minutes/week) was higher in the intervention group post-intervention (MD 141.4; 95% CI 62.9, 219.9). The proportion of participants at "maintenance" stage-of-change for physical activity was higher in the intervention group (56.3 vs. 31.2%). App use was associated with lower glycaemic index and less energy from free sugars, but not with physical activity. Conclusion: A behavioral-lifestyle intervention in pregnancy supported by a smartphone app improved dietary intakes, physical activity, and motivation to engage in exercise.

Novel DLX3 variants in amelogenesis imperfecta with attenuated tricho-dento-osseous syndrome.

OBJECTIVES: Variants in DLX3 cause tricho-dento-osseous syndrome (TDO, MIM #190320), a systemic condition with hair, nail and bony changes, taurodontism and amelogenesis imperfecta (AI), inherited in an autosomal dominant fashion. Different variants found within this gene are associated with different phenotypic presentations. To date, six different DLX3 variants have been reported in TDO. The aim of this paper was to explore and discuss three recently uncovered new variants in DLX3. SUBJECTS AND METHODS: Whole-exome sequencing identified a new DLX3 variant in one family, recruited as part of an ongoing study of genetic variants associated with AI. Targeted clinical exome sequencing of two further families revealed another new variant of DLX3 and complete heterozygous deletion of DLX3. For all three families, the phenotypes were shown to consist of AI and taurodontism, together with other attenuated features of TDO. RESULTS: c.574delG p.(E192Rfs*66), c.476G>T (p.R159L) and a heterozygous deletion of the entire DLX3 coding region were identified in our families. CONCLUSION: These previously unreported variants add to the growing literature surrounding AI, allowing for more accurate genetic testing and better understanding of the associated clinical consequences.
