RESUMO
OBJECTIVES: Radiographic evaluation of the wisdom teeth (third molar) formation is a widely used age assessment method for adolescents and young adults. This systematic review examines evidence on the agreement between Demirjian's development stages of the third molar and chronological age. METHODS: We searched four databases up until May 2016 for studies reporting Demirjian's stages of third molar and confirmed chronological age of healthy individuals aged 10-25 years. Heterogeneity test of the included studies was performed. RESULTS: We included 21 studies from all continents except Australia, all published after 2005. The mean chronological age for Demirjian's stages varied considerably between studies. The results from most studies were affected by age mimicry bias. Only a few of the studies based their results on an unbiased age structure, which we argue as important to provide an adequate description of the method's ability to estimate age. CONCLUSION: Observed study variation in the timing of Demirjian's development stages for third molars has often been interpreted as differences between populations and ethnicities. However, we consider age mimicry to be a dominant bias in these studies. Hence, the scientific evidence is insufficient to conclude whether such differences exist. KEY POINTS: ⢠There is significant heterogeneity between studies evaluating age assessment by Demirjian's third molar development. ⢠Most of the studies were subject to the selection bias age mimicry which can be a source of heterogeneity. ⢠Presence of age mimicry bias makes it impossible to compare and combine results. These biased studies should not be applied as reference studies for age assessment.

OBJECTIVES: The aim of this paper is to describe a conceptual framework for how to consider health equity in the Grading Recommendations Assessment and Development Evidence (GRADE) guideline development process. STUDY DESIGN AND SETTING: Consensus-based guidance developed by the GRADE working group members and other methodologists. RESULTS: We developed consensus-based guidance to help address health equity when rating the certainty of synthesized evidence (i.e., quality of evidence). When health inequity is determined to be a concern by stakeholders, we propose five methods for explicitly assessing health equity: (1) include health equity as an outcome; (2) consider patient-important outcomes relevant to health equity; (3) assess differences in the relative effect size of the treatment; (4) assess differences in baseline risk and the differing impacts on absolute effects; and (5) assess indirectness of evidence to disadvantaged populations and/or settings. CONCLUSION: The most important priority for research on health inequity and guidelines is to identify and document examples where health equity has been considered explicitly in guidelines. Although there is a weak scientific evidence base for assessing health equity, this should not discourage the explicit consideration of how guidelines and recommendations affect the most vulnerable members of society.

OBJECTIVES: This article introduces the rationale and methods for explicitly considering health equity in the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology for development of clinical, public health, and health system guidelines. STUDY DESIGN AND SETTING: We searched for guideline methodology articles, conceptual articles about health equity, and examples of guidelines that considered health equity explicitly. We held three meetings with GRADE Working Group members and invited comments from the GRADE Working Group listserve. RESULTS: We developed three articles on incorporating equity considerations into the overall approach to guideline development, rating certainty, and assembling the evidence base and evidence to decision and/or recommendation. CONCLUSION: Clinical and public health guidelines have a role to play in promoting health equity by explicitly considering equity in the process of guideline development.

OBJECTIVES: To evaluate selected European printed dietary guidelines for pregnant women and parents of infants and toddlers using the suitability assessment of materials (SAM) method. METHODS: A descriptive study to determine the suitability of 14 printed dietary guidelines from 7 European countries based on deductive quantitative analyses. RESULTS: Materials varied greatly in format and content: 35.7% of materials were rated superior and 64.3% were rated adequate according to the overall SAM score for patient education material. None of the materials were scored not suitable. Among the categories, the highest average scores were for layout and typography and the lowest average scores were for cultural appropriateness and learning stimulation and motivation. Interrater reliability ranged from Cohen's kappa of 0.37 to 0.62 (mean, 0.41), indicating fair to moderate agreement among the 3 investigators. CONCLUSIONS AND IMPLICATIONS: Overall, the suitability of the assessed printed dietary guidelines was adequate. Based on the SAM methodology, printed dietary guidelines may increase in suitability by emphasizing aspects related to health literacy and accommodating the needs of different food cultures within a population.

BACKGROUND: The impact of socio-economic position and integration level on the observed ethnic differences in dietary habits has received little attention. OBJECTIVES: To identify and describe dietary patterns in a multi-ethnic population of pregnant women, to explore ethnic differences in odds ratio (OR) for belonging to a dietary pattern, when adjusted for socio-economic status and integration level and to examine whether the dietary patterns were reflected in levels of biomarkers related to obesity and hyperglycaemia. DESIGN: This cross-sectional study was a part of the STORK Groruddalen study. In total, 757 pregnant women, of whom 59% were of a non-Western origin, completed a food frequency questionnaire in gestational week 28±2. Dietary patterns were extracted through cluster analysis using Ward's method. RESULTS: Four robust clusters were identified where cluster 4 was considered the healthier dietary pattern and cluster 1 the least healthy. All non-European women as compared to Europeans had higher OR for belonging to the unhealthier dietary patterns 1-3 vs. cluster 4. Women from the Middle East and Africa had the highest OR, 21.5 (95% CI 10.6-43.7), of falling into cluster 1 vs. 4 as compared to Europeans. The ORs decreased substantially after adjusting for socio-economic score and integration score. A non-European ethnic origin, low socio-economic and integration scores, conduced higher OR for belonging to clusters 1, 2, and 3 as compared to cluster 4. Significant differences in fasting and 2-h glucose, fasting insulin, glycosylated haemoglobin (HbA1c), insulin resistance (HOMA-IR), and total cholesterol were observed across the dietary patterns. After adjusting for ethnicity, differences in fasting insulin (p=0.015) and HOMA-IR (p=0.040) across clusters remained significant, despite low power. CONCLUSION: The results indicate that socio-economic and integration level may explain a large proportion of the ethnic differences in dietary patterns.
RESUMO
OBJECTIVE: to explore experiences with nutrition-related information during routine antenatal care among women of different ethnical backgrounds. DESIGN: individual interviews with seventeen participants were conducted twice during pregnancy. Data collection and analysis were inspired by an interpretative phenomenological approach. SETTING: participants were purposively recruited at eight Mother and Child Health Centres in the area of Oslo, Norway, where they received antenatal care. PARTICIPANTS: participants had either immigrant backgrounds from African and Asian countries (n=12) or were ethnic Norwegian (n=5). Participants were pregnant with their first child and had a pre-pregnancy Body Mass Index above 25 kg/m(2). FINDINGS: participants experienced that they were provided with little nutrition-related information in antenatal care. The information was perceived as presented in very general terms and focused on food safety. Weight management and the long-term prevention of diet-related chronic diseases had hardly been discussed. Participants with immigrant backgrounds appeared to be confused about information given by the midwife which was incongruent with their original food culture. The participants were actively seeking for nutrition-related information and had to navigate between various sources of information. CONCLUSIONS: the midwife is considered a trustworthy source of nutrition-related information. Therefore, antenatal care may have considerable potential to promote a healthy diet to pregnant women. Findings suggest that nutrition communication in antenatal care should be more tailored towards women's dietary habits and cultural background, nutritional knowledge as well as level of nutrition literacy.

Socioeconomic differences in overweight are well documented, but most studies have only used one or two indicators of socioeconomic position (SEP). The aim of the present study was to explore the relative importance of indicators of SEP (occupation, education and income) in explaining variation in BMI and waist:hip ratio (WHR), and the mediating effect of work control and lifestyle factors (dietary patterns, smoking and physical activity). The Oslo Health Study, a cross-sectional study, was carried out in 2000-1, Oslo, Norway. Our sample included 9235 adult working Oslo citizens, who attended a health examination and filled in two complementary FFQ with < 20% missing responses to food items. Four dietary patterns were identified through factor analysis, and were named 'modern', 'Western', 'traditional' and 'sweet'. In multivariate models, BMI and WHR were inversely associated with education (P < 0.001/P < 0.001) and occupation (P = 0.002/P < 0.001), whereas there were no significant associations with income or the work control. The 'modern' (P < 0.001) and the 'sweet' (P < 0.001) dietary patterns and physical activity level (P < 0.001) were inversely associated, while the 'Western' dietary pattern (P < 0.001) was positively associated with both BMI and WHR. These lifestyle factors could not fully explain the socioeconomic differences in BMI or WHR. However, together with socioeconomic factors, they explained more of the variation in WHR among men (21%) than among women (7%).

Despite a general improvement of the living standard in Norway, disparities in living conditions and health between socio-economic groups have increased over the last decades. This article discusses present knowledge on socio-economic differences in diet in Europe and particularly in Norway. Several international and Norwegian studies indicate that the diet of lower socio-economic groups tends to compare poorly to that of higher groups on a number of health-related aspects. More documentation is needed on how diet and food selection differs across population groups; moreover, better knowledge about why these differences exist and persist is needed. This is important for making interventions and other preventive efforts effective in eliminating unfavourable dietary differences.
