Nutritional Implications of Baby-Led Weaning and Baby Food Pouches as Novel Methods of Infant Feeding: Protocol for an Observational Study.

BACKGROUND: The complementary feeding period is a time of unparalleled dietary change for every human, during which the diet changes from one that is 100% milk to one that resembles the usual diet of the wider family in less than a year. Despite this major dietary shift, we know relatively little about food and nutrient intake in infants worldwide and virtually nothing about the impact of baby food "pouches" and "baby-led weaning" (BLW), which are infant feeding approaches that are becoming increasingly popular. Pouches are squeezable containers with a plastic spout that have great appeal for parents, as evidenced by their extraordinary market share worldwide. BLW is an alternative approach to introducing solids that promotes infant self-feeding of whole foods rather than being fed purées, and is popular and widely advocated on social media. The nutritional and health impacts of these novel methods of infant feeding have not yet been determined. OBJECTIVE: The aim of the First Foods New Zealand study is to determine the iron status, growth, food and nutrient intakes, breast milk intake, eating and feeding behaviors, dental health, oral motor skills, and choking risk of New Zealand infants in general and those who are using pouches or BLW compared with those who are not. METHODS: Dietary intake (two 24-hour recalls supplemented with food photographs), iron status (hemoglobin, plasma ferritin, and soluble transferrin receptor), weight status (BMI), food pouch use and extent of BLW (questionnaire), breast milk intake (deuterium oxide "dose-to-mother" technique), eating and feeding behaviors (questionnaires and video recording of an evening meal), dental health (photographs of upper and lower teeth for counting of caries and developmental defects of enamel), oral motor skills (questionnaires), and choking risk (questionnaire) will be assessed in 625 infants aged 7.0 to 9.9 months. Propensity score matching will be used to address bias caused by differences in demographics between groups so that the results more closely represent a potential causal effect. RESULTS: This observational study has full ethical approval from the Health and Disability Ethics Committees New Zealand (19/STH/151) and was funded in May 2019 by the Health Research Council (HRC) of New Zealand (grant 19/172). Data collection commenced in July 2020, and the first results are expected to be submitted for publication in 2022. CONCLUSIONS: This large study will provide much needed data on the implications for nutritional intake and health with the use of baby food pouches and BLW in infancy.

The relative frequency of paediatric oral and maxillofacial pathology in New Zealand: A 10-year review of a national specialist centre.

BACKGROUND: There has been no previous report of the prevalence of paediatric oral and maxillofacial pathology in a New Zealand oral pathology diagnostic service. AIM: The aim of this study was to review cases of paediatric oral pathology to determine relative frequencies of oral lesions in this age group. DESIGN: Paediatric oral pathology cases (≤15 years of age) received between 2007 and 2016 were retrieved from the electronic database of the Oral Pathology Centre, University of Otago. Data collected included diagnoses (categorised into 12 groups), age at diagnosis, and gender. The prevalence of each diagnosis was calculated in terms of percentage of all diagnoses made. Male-to-female ratio and mean age at diagnosis were also determined. RESULTS: A total of 1139 paediatric cases were identified representing 5.2% of all cases. The most common diagnostic group was salivary gland pathology (25.4%), followed by dental (24.8%) pathology. The most prevalent lesion was mucocoele (23%), followed by dental follicle (14.1%). Malignancies were rare with only two cases identified. CONCLUSION: The findings provide an insight into the prevalence of paediatric oral pathology for clinicians. Mucocoele was the most common diagnosis made, suggesting a high prevalence of soft tissue injury as a main presenting concern warranting diagnosis and management through biopsy.

Curriculum development in final year dentistry to enhance competency and professionalism for contemporary general dental practice.

INTRODUCTION: General dentistry is the most common area of practice, and new dentists must have the competency and skills to safely deliver patient care. In New Zealand (NZ), completion of a 5-year Bachelor of Dental Surgery (BDS) degree enables graduates to register with the Dental Council in NZ. This necessitates that the clinical component of the curriculum in final year dentistry (BDS5) transparently delivers learning opportunities and evaluates competency for independent practice. A review of the BDS5 Clinical Practice course was undertaken in 2015 and a revised curriculum introduced in 2016. CURRICULUM: We present a BDS5 curriculum for a Clinical Practice course that is learner focused with emphasis on comprehensive patient-centred care, competency and professional practice. Learning opportunities and assessment processes are described alongside teacher training. These changes have provided students scaffolding to support clinical and professional development, and accommodate different learning preferences. The outcomes align with the competency requirements of the NZ regulatory body for registration as a general dental practitioner. Since its introduction 3 years ago, ongoing feedback from students and staff has been positive and indicates the curriculum is effective in achieving its objectives. CONCLUSIONS: This curriculum provides a firm foundation for students transitioning to independent clinical practice in the community and supports the professional development of clinical teachers. It may also be translated to other areas of health education to ensure the delivery of quality holistic patient care.

An exploratory study of the acceptability of delivering oral health information in community pharmacies.

OBJECTIVE: The community pharmacy is an accessible service which, with further training and support, could be used to deliver oral health messages. This is important especially for those with systemic diseases such as diabetes mellitus and cardiovascular disease, where the oral environment may have a negative impact. This qualitative study assessed the feasibility of pharmacists delivering oral health messages in community pharmacies. DESIGN AND METHODS: Semi-structured interviews were conducted with 49 pharmacists in Dunedin and Auckland, New Zealand, with a focus on the pharmacists' current knowledge, attitudes and possibilities for providing oral health information to patients with diabetes and cardiovascular disease. FINDINGS: There is potential for community pharmacists to provide oral health information to patients, dependent on the approach of the pharmacist and the patient response. The majority of pharmacists agreed that providing oral health advice was within their role; however, few did so proactively. They highlighted a lack of available resources relating to oral health and systemic disease. Further training relating to oral health and systemic disease would be necessary to provide the knowledge to support any resources. The preferred option by pharmacists for such training was an evening course or workshop.

The working practices and job satisfaction of dental hygienists in New Zealand.

OBJECTIVES: To describe the current working practices and level of job satisfaction of dental hygienists in New Zealand. METHODS: Postal survey of all dental hygienists on the New Zealand Dental Council's database. An initial mailing was followed by a 3-week follow-up. Information was sought on respondents' demographic characteristics, current occupation and working practice, history of career breaks, continuing education and career satisfaction. RESULTS: 213 responses were received (73.2%); 90.6% were currently working as hygienists, mostly in private practice. Many worked part time, particularly those with children. Almost 50% of respondents had taken at least one career break, most frequently for childrearing. The mean time taken in career breaks was 3.6 years. Overall, dental hygienists reported high levels of satisfaction with their careers and their income. Older hygienists had higher career satisfaction scores. Most respondents were actively involved in continuing education. Almost half were interested in expanding the range of procedures they perform. Over one-third plan to retire within the next 10 years. CONCLUSIONS: While many hygienists take career breaks and work part time, most have a high level of career satisfaction, actively participate in continuing education, and are satisfied with their remuneration.
