The aims of this study were to estimate the average maximum mouth opening and range of mouth opening in a representative sample of the Irish adult population, to compare mouth opening in patients with and without signs or symptoms of temporomandibular joint (TMJ) dysfunction syndrome and to investigate the association between mouth opening and stature among populations. As part of the Irish National Survey of Adult Oral Health, maximum mouth opening was measured and questionnaire data collected for 1513 adults, aged 16–99 years. The average maximum mouth opening was 43 mm for males and 41 mm for females. Mouth opening was found to reduce with age, independent of gender. No link was found between reduced mouth opening and TMJ dysfunction or between mouth opening and stature in populations. [ABSTRACT FROM AUTHOR]

Background: Childhood obesity is a significant global health issue. National level data on long-term secular trends are relatively sparse. Methods: Data were obtained from three large-scale surveys of school-aged children in Ireland involving measurements of height and weight in 1948, the 1970s and 2002. Results: Significant increases in height and weight were observed in both boys and girls and in all age groups across the decades. The increases in weight were disproportionate to the trends in height. While boys aged 14 years were 23 cm taller 2002 than in 1948, their average weight was 61 kg, compared with 37 kg in 1948, an increase of 24 kg. A substantial proportion of the increase in weight is seen between the 1970s and 2002. Conclusions: The data provide stark and compelling evidence on the evolution of the obesity epidemic in Irish children in tandem with the increase in economic prosperity. [ABSTRACT FROM AUTHOR]
