Weight gain and dietary intake during pregnancy in industrialized countries - a systematic review of observational studies
Background: Gestational weight gain (GWG) above the recently recommended ranges is likely to be related to adverse pregnancy outcomes and therefore a challenge in industrialized countries. Aims: We conducted a systematic review on observational studies in order to gain more evidence on whether diets with lower caloric/protein content or other diets might be associated with lower GWG. Methods: We searched in MEDLINE and EMBASE for observational studies written in English or German reporting associations between diet and GWG in singleton pregnancies of healthy women in industrialized countries. Results: We identified 12 studies which met the inclusion criteria. Five studies suggested significant positive associations between energy intake and GWG, whereas three found no significant association. Further significant positive associations of GWG were reported with respect to protein intake, animal lipids, energy density and a number of different food servings per day, whereas intake of carbohydrates and vegetarian diet were associated with less GWG. Conclusions: We suggest that GWG might be reduced by lower energy intake in pregnancy
Inventory of current EU paediatric vision and hearing screening programmes
Background: We examined the diversity in paediatric vision and hearing screening
programmes in Europe.
Methods: Themes relevant for comparison of screening programmes were derived from
literature and used to compile three questionnaires on vision, hearing and public-health
screening. Tests used, professions involved, age and frequency of testing seem to influence
sensitivity, specificity and costs most. Questionnaires were sent to ophthalmologists,
orthoptists, otolaryngologists and audiologists involved in paediatric screening in all EU fullmember,
candidate and associate states. Answers were cross-checked.
Results: Thirty-nine countries participated; 35 have a vision screening programme, 33 a
nation-wide neonatal hearing screening programme. Visual acuity (VA) is measured in 35
countries, in 71% more than once. First measurement of VA varies from three to seven years
of age, but is usually before the age of five. At age three and four picture charts, including Lea
Hyvarinen are used most, in children over four Tumbling-E and Snellen. As first hearing
screening test otoacoustic emission (OAE) is used most in healthy neonates, and auditory
brainstem response (ABR) in premature newborns. The majority of hearing testing
programmes are staged; children are referred after one to four abnormal tests. Vision
screening is performed mostly by paediatricians, ophthalmologists or nurses. Funding is
mostly by health insurance or state. Coverage was reported as >95% in half of countries, but
reporting was often not first-hand.
Conclusion: Largest differences were found in VA charts used (12), professions involved in
vision screening (10), number of hearing screening tests before referral (1-4) and funding
