Do implant-supported dentures facilitate efficacy of eating more healthily?

UNLABELLED: Edentulous persons have poor diet quality demonstrating a need for dietary intervention. Implant-supported mandibular overdentures (IODs) have functional advantages over conventional dentures (CD), but whether they enhance the ability to eat more healthily following dietary advice is unknown. OBJECTIVES: This study aimed to compare the effectiveness of dietary intervention between IODs and CD patients. METHODS: Edentulous adults (28 IOD and 26 CD) received customised dietary advice. The percentage contribution of dietary fats, carbohydrate and protein to energy (kcal) intake, dietary intakes of fibre, fruits, vegetables and antioxidants, and plasma antioxidants were assessed pre- and at 3 and 6 months post-dietary intervention. RESULTS: Both groups increased fruit and vegetable intake at 3 and 6 months following dietary intervention but intakes between groups did not differ. The IOD group had reduced % energy from total fat at 3 and 6 months and from saturated fat at 3 months. The CD group had reduced % energy from saturated by 6 months. The IOD group had a significantly lower % energy intake from saturated fat at 3 months and higher intake of non-starch polysaccharide (NSP) compared with the CD group. Both groups showed improvements in serum antioxidant status but the IOD group had significantly higher plasma antioxidant capacity post intervention compared with the CD group. CONCLUSIONS: Dietary intervention benefits denture patients. IOD patients showed moderately greater dietary improvements compared with conventional denture patients.

Development of a patient-based questionnaire about emotional and social issues related to eating with dentures.

OBJECTIVES: In order to fully assess the impact of prosthetic rehabilitation and to formulate appropriate dietary advice, in-depth information about patients' experiences of eating with dentures is needed. The objective of this study was to develop and validate a questionnaire that accurately reflected the real concerns of patients with dental prostheses about the aspects of their life related to eating, using detailed information derived from qualitative interviews with patients. METHODS: Themes around factors related to eating with dentures were derived from interviews with patients (n=66) with either implant-supported mandibular over-dentures or conventional dentures. The themes were used to design a self-completed questionnaire with questions scored on a visual analogue scale and additionally questions answered using free text. The content and face validity of the questionnaire was tested on a different group of patients (n=10) with implant-supported mandibular over-dentures ('implant-supported') or conventional dentures. Test-retest reliability analysis was conducted on a further group of 30 patients (n=15 implant-supported; n=15 conventional dentures). RESULTS: A questionnaire has been developed with 33 questions scored on a visual analogue scale and 31 open questions designed to collect further information as free text. Themes identified were around social, emotional and practical issues about eating. The instrument has good internal reliability with a Cronbach alpha values of 0.86-0.95 and good test-retest reliability with intra-class correlation coefficients 0.87-0.92 across the domains. CONCLUSIONS: A patient-based instrument has been developed to measure emotional and social issues related to eating with dentures (ESIRE questionnaire). The questionnaire will be a useful tool in future trials of prosthetic rehabilitation.

Parental perceptions of weight status in children: the Gateshead Millennium Study.

OBJECTIVES: To investigate parents' perceptions of weight status in children and to explore parental understanding of and attitudes to childhood overweight. DESIGN: Questionnaires and focus groups within a longitudinal study. SUBJECTS: 536 parents of Gateshead Millennium Study children, of which 27 attended six focus groups. MAIN OUTCOME MEASURES: Parents' perception of their child's weight status according to actual weight status as defined by International Obesity Taskforce (IOTF) cutoffs. Focus group outcomes included parental awareness of childhood overweight nationally and parental approaches to identifying overweight children. RESULTS: The sensitivity of parents recognising if their child was overweight was 0.31. Prevalence of child overweight was underestimated: 7.3% of children were perceived as 'overweight' or 'very overweight' by their parents, 23.7% were identified as overweight or obese using IOTF criteria. 69.3% of parents of overweight or obese children identified their child as being of 'normal' weight. During focus groups parents demonstrated an awareness of childhood overweight being a problem nationally but their understanding of how it is defined was limited. Parents used alternative approaches to objective measures when identifying overweight in children such as visual assessments and comparisons with other children. Such approaches relied heavily on extreme and exceptional cases as a reference point. The apparent lack of relevance of childhood overweight to their child's school or own community along with scepticism towards both media messages and clinical measures commonly emerged as grounds for failing to engage with the issue at a personal level. CONCLUSION: Parents' ability to identify when their child was overweight according to standard criteria was limited. Parents did not understand, use or trust clinical measures and used alternative approaches primarily reliant on extreme cases. Such approaches underpinned their reasoning for remaining detached from the issue. This study highlights the need to identify methods of improving parental recognition of and engagement with the problem of childhood overweight.
