- BackgroundOtalgia is an important symptom leading children to seek health care in general practice and it can be a symptom of acute otitis media (AOM). The course of AOM can be of importance when grading severity of AOM.The aim of this study was to assess tympanic membrane TM appearance in children aged 2–16 years with otalgia in general practice and to follow their signs and symptoms over time.MethodThe children were examined at four rural health care centers in Lapland, Sweden. Symptoms such as otalgia, fever and the general condition were recorded together with endoscopic TM images and tympanometry results and stored in a central database. The same procedures were applied at follow-up visits after 3 days, 7 days and 3 months. The symptoms were given scores 0–2, the tympanograms were labeled as type A, type C and type B (scores 0–4–8) whereas TM images were graded according to the OMGRADE scale for TM´s (score 0–8). An assessment group set a diagnosis asynchronously after a consensus discussion. Diagnoses: normal, otitis media with effusion, AOM, bullous myringitis without AOM (BM), bullous myringitis with AOM (bAOM) and AOM with perforation or a wet and chagrinated appearance of the TM (pAOM). The diagnoses were scrutinized for any difference in presentation of symptoms. The course of signs and symptoms was followed up at return visits.ResultsThe children showed a normal TM and tympanogram in 19%, otitis media with effusion in 32% and AOM in 49% at first visit. The majority of children reported no symptoms after 3 days. The children with bilateral AOM reported slightly more symptoms and the BM/bAOM groups reported fewer symptoms than children with AOM. A pAOM with a chagrinated TM was found in 19% and showed a prolonged return to normal tympanograms. Forty percent of the children who presented with a chagrinated TM (pAOM) at first visit still had type-B tympanograms after 3 months.Conclusions Half of the children with otalgia were diagnosed with AOM. Symptoms resolved faster than signs. The chagrinated TM appeared to be associated with prolonged middle ear effusion.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Deficiency of folic acid increases the risk for neural tube defects among newborn children and megaloblastic anaemia in the mother. The aim of this study was to make a survey of how midwives working in maternity health care, family planning guidance, and specialist prenatal care in a Swedish county inform women of childbearing age about folic acid. The questionnaire study showed that 79% of the midwives informed the women about folic acid. Usually, the women received information first when they asked for it and midwifes were less prone to inform young women about folic acid. 87% of the midwives felt that they did not know enough about folic acid. Conclusions: Midwives play an important role in information about the need of folic acid intake for women in childbearing age. Changes in local routines, guidelines and further education of midwifes would subsequently provide information about the importance of folic acid to women in childbearing age.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- BackgroundA well-balanced nutritious diet is important for the pregnant woman and the growing fetus, as well as for their future health. Poor nutrition results from both over-consumption of energy-rich foods which can lead to a higher weight gain than is healthy and under-nutrition of essential nutrients. Food intake is regulated in complex biological systems by many factors, where steroid hormone is one factor involved.The overall aim of this thesis is to describe dietary intake, vitamin D levels, dietary information and dietary changes, and to study the relation between allopregnanolone and weight gain during pregnancy and postpartum.Methods Study I was a qualitative study with focus group interviews with 23 pregnant women. The text was analysed with content analysis. Study II was a quantitative cross-sectional study conducted in early pregnancy (n=209) with a reference group (n=206). Self-reported dietary data from a questionnaire was analysed using descriptive comparative statistics and a cluster analysis model (Partial Least Squares modelling). Study III had a quantitative longitudinal design. Vitamin D concentrations were analysed in 184 women, collected on five occasions during pregnancy and postpartum. Descriptive comparative statistics and a linear mixed model were used. Study IV was a quantitative longitudinal study with 60 women. Concentrations of allopregnanolone were analysed in gestational week 12 and 35. Descriptive and comparative statistics as well as Spearman’s correlation (rho) were used to describe the relationship between weight gain and allopregnanolone concentrations. Results The focus group interviews showed that women wanted to know more about different foods to reduce any risk for their child but the information about foods was partly up to themselves to find out. They expressedfeelingsof insecurityand guiltif they accidentallyate something“forbidden”. The recommendationswere followedas best as possiblealong withcommon sense todeal with dietchanges. The main themes were “Finding out by oneself”, “Getting professional advice when health problems occur”, “Being uncertain” and “Being responsible with a pinch of salt”. Some differences in the dietary patterns were found among the pregnant women compared to references, with less, vegetables (47 g/day), potatoes/rice/pasta (31 g/day), meat/fish (24 g/day) and intake of alcohol and tobacco/snuff but a higher intake of supplements. Bothpregnant women and referenceshad intakes offolatethrough diet45% (pregnant) and 22% (references) lower than current recommendations(500vs400g/day). Vitamin Dintake was34% lower than the recommendationsof 10mg/day. At least a third of the participants had insufficient plasma levels below 50 nmol/L of vitamin D. Season was a strong factor influencing the longitudinal pattern. Gestational week, season, total energy intake, dietary intake of vitamin D, and multivitamin supplementation over the previous 14 days were factors related to vitamin D levels. A correlation betweenallopregnanoloneconcentrations ingestationalweek 35and weight gainin weeks12–35was seen (p = 0.016). Therewas alsoa correlation betweenthe increase inallopregnanolone(weeks12–35) andweight gain(see above) (p = 0.028). ConclusionsDietary recommendations were described as contradictory and confusing and the dietary advice felt inadequate. The women faced their diet changes and sought information on their own but would have wished for more extensive advice from the midwife. The intake of vitamins essential for pregnancy was lower than recommended, which is also confirmed by low plasma levels of vitamin D in at least one third of the pregnant women. Vitamin D levels peaked in late pregnancy. Aside from gestational week and season which were related to plasma levels, intake from foods and supplements also affected the levels. Reasons for weight gain are complex and depend on many factors. Allopregnanolone is a factor that was seen to relate to the weight gain of the studied pregnant women.

Tidskriftsartikel (refereegranskat)abstract
- Background: A woman's nutritional status before conception and during pregnancy is important for maternal health and the health of the foetus. The aim of the study was to compare diet intake in early pregnant women with non-pregnant women. Methods: Between September 2006 and March 2009, 226 women in early pregnancy were consecutively recruited at five antenatal clinics in Northern Sweden. Referent women (n = 211) were randomly selected from a current health screening project running in the same region (the Vasterbotten Intervention Program; VIP). We collected diet data with a self-reported validated food frequency questionnaire with 66 food items/food aggregates, and information on portion size, alcohol consumption, and supplement intake. Data were analysed using descriptive, comparative statistics and multivariate partial least square modelling. Results: Intake of folate and vitamin D from foods was generally low for both groups. Intake of folate and vitamin D supplements was generally high in the pregnant group and led to significantly higher total estimated intake of vitamin D and folate in the pregnant group. Iron intake from foods tended to be lower in pregnant women although iron supplement intake evened out the difference with respect to iron intake from foods only. Energy intake was slightly lower in pregnant women but not significant, a reflection of that they reported consuming significantly less of potatoes/rice/pasta, meat/fish, and vegetables (grams/day) than the women in the referent group. Conclusions: In the present study, women in early pregnancy reported less intake of vegetables, potatoes, meat, and alcohol than non-pregnant women. As they also had a low intake (below the Nordic Nutritional Recommendations) of folate, vitamin D, and iron from foods, some of these women and their unborn children are possibly at risk for adverse effects on the pregnancy and birth outcome.

- Objective: Large weight gain during pregnancy is a risk factor for complications for mother and fetus. Hunger and satiety are regulated in the hypothalamus, where the gamma-amino-butyric acid system (GABA) has an important role. Allopregnanolone, a progesterone metabolite, increases during pregnancy and is a potent GABA-A receptor modulating steroid. Allopregnanolone has been shown to induce overeating in rodents. The aim was to investigate whether there is a relationship between weight gain and allopregnanolone concentrations during pregnancy in humans. Design: A longitudinal, cohort study. Methods: Pregnant women (n = 56) were recruited in primary care in northern Sweden. Allopregnanolone concentrations in plasma were measured using radioimmunoassay and weight was measured in gestational weeks 12 and 35. Results: Weight increase correlated significantly to allopregnanolone in late pregnancy increase (r(s) = 0.320; P = 0.016), indicating a positive relationship between weight increase and allopregnanolone increase. A positive relationship was also noted between allopregnanolone in the 35th gestational week and weight increase. Women who gained = 11 kg during pregnancy showed higher allopregnanolone concentrations in week 35 and higher increase compared to women who increased < 11 kg (P = 0.006 and P = 0.009 resp.). There was no difference in weight or allopregnanolone concentrations at the onset of pregnancy. Conclusions: The results show a relationship between weight gain during pregnancy and increase in allopregnanolone concentrations.

- Low vitamin D levels during pregnancy may have negative consequences for the health of both the mother and child. Cross-sectional studies in childbearing women suggest that vitamin D levels are low during pregnancy, but few studies have followed the same women during pregnancy and postpartum. The aims of this study were to longitudinally assess vitamin D status during pregnancy and postpartum and identify the factors associated with vitamin D status in pregnant women in northern Sweden. Between September 2006 and March 2009, 184 women were consecutively recruited at five antenatal primary care clinics. Blood was sampled, and dietary intake was estimated using a food frequency questionnaire with 66 food items/food aggregates and questions on the intake of vitamin supplements at gestational weeks 12, 21, and 35, as well as at 12 and 29 weeks after birth. Plasma 25(OH) vitamin D levels were analyzed using liquid chromatography tandem-mass spectrometry. At least one-third of the women had 25(OH) vitamin D levels <50 nmol/L on at least one sampling occasion. Plasma levels increased slightly over the gestation period and peaked in late pregnancy. The levels reverted to the baseline levels after birth. Multivariate analysis showed that gestational and postpartum week, season, dietary intake of vitamin D, and vitamin supplementation were significantly related to plasma levels. There was also an influence of season on the longitudinal concentration patterns. In conclusion, more than one-third of the women studied had low 25(OH) vitamin D levels, and gestational and postpartum week was related to 25(OH) vitamin D levels after adjustment for season and vitamin D intake.

- Aims: To study longitudinal patterns of tobacco use over a 10-year period among middle-aged men and women in Västerbotten County, Northern Sweden.Methods: The study is based on data from the 16,486 (8800 women and 7686 men) in the Västerbotten Intervention Programme (VIP) where people were invited to a health screening and counselling programme at 30, 40, 50 and 60 years of age.Results: Smoking decreased from 22.3% to 15.6% among women and from 18.5% to 12.7% among men. Use of snus (Swedish moist snuff) increased from 3.1% to 6.0% among women and from 24.6% to 26.3% among men. The number of people who used both snus and cigarettes was stable: 0.5% to 0.8% from baseline to follow-up for women, and 4.1% to 3.3% for men. The number of tobacco-free adults increased from 75.2% to 79.2% for women and from 61.1% to 64.3% for men. Of those who became smoke-free during the 10-year follow-up period, 80% of the women and 66% of the men quit smoking without transitioning to snus use.Conclusions: The majority of middle-aged Swedish men and women in this cohort that quit smoking did so without becoming snus dependent. In spite of an increasing use of snus, overall there was a decline in the number of people using tobacco products.

- Over a five-year period, 1991-1995, the vitamin B12 market in Sweden increased three-fold, from approximatelyy 2 million U.S. dollars to approximately 6 million U.S. dollars. Most prescriptions, approximately 60%, originated from primary health care. The attitudes, values and knowledge of the family physicians/general practitioners were elucidated by a questionnaire study with visuo-analogue opinion scales, evaluating 24 basic statements on problems associated with the management of vitamin B12 deficiency. The questionnaire was sent to a representative sample of 506 family physicians/general practitioners. Response rate was 74%. Dropout analysis supported the view that responders provided a representative sample of Swedish FP/GPs. Analysis of the answers was compatible with the hypothesis that the mentioned increase in Swedish B12 market reflected increased awareness in primary health care about the biochemical, pathophysiological and social problems associated with vitamin B12 deficiency.
