Dental and Periodontal Health in Acute Intermittent Porphyria
In the inherited metabolic disorder acute intermittent porphyria (AIP), high sugar intake
prevents porphyric attacks due to the glucose effect and the following high insulin levels that
may lower AIP disease activity. Insulin resistance is a known risk factor for periodontitis and
sugar changes diabetogenic hormones and affects dental health. We hypothesized differences in
homeostasis model assessment (HOMA) scores for insulin resistance in AIP cases vs. controls and in
those with periodontitis. Our aim was to systematically study dental health in AIP as poor dental
health was previously only described in case reports. Further, we aimed to examine if poor dental
health and kidney failure might worsen AIP as chronic inflammation and kidney failure might
increase disease activity. In 47 AIP cases and 47 matched controls, X-rays and physical examination
of clinical attachment loss (CAL), probing pocket depth (PPD), and decayed missing filled teeth
(DMFT) were performed. Dietary intake was evaluated through a diet logbook. Plasma cytokines
and diabetogenic hormones were measured using multiplex technology and urine porphobilinogen
and kidney and liver function by routine methods. An excel spreadsheet from the University of
Oxford was used to estimate HOMA scores; beta cell function, HOMA%B (%B), insulin sensitivity,
HOMA%S (%S), and insulin resistance HOMA-IR (IR), based on glucose and plasma (P) C-peptide.
The Wilcoxon matched-pairs signed rank test, the Mann–Whitney U-test, and Spearman’s nonparametric correlation were used. Insulin (p = 0.007) and C-peptide (p = 0.006) were higher in the AIP
cases with periodontitis versus those without. In AIP patients, the liver fibrosis index 4 correlated
with DMFT (p < 0.001) and CAL ≥4 mm (p = 0.006); the estimated glomerular filtration rate correlated
with DMFT (p < 0.001) and CAL ≥4 mm (p = 0.02). CAL ≥4 mm was correlated with chemokine
ligand 11 and interleukin (IL)-13 (p = 0.04 for both), and PPD >5 mm was correlated with plasminogen
activator inhibitor-1 (p = 0.003) and complement component 3 (p = 0.02). In conclusion, dental health
in AIP cases was correlated with insulin resistance, inflammatory markers, and biomarkers of kidney
and liver function, demonstrating that organ damage in the kidney and liver are associated with
poorer dental health
Introduction of fish and other foods during infancy and risk of asthma in the All Babies In Southeast Sweden cohort study
The etiology of asthma includes lifestyle factors. Breastfeeding and introduction of complementary foods have been suggested to affect asthma risk, but the scientific foundation is not solid. Children from the birth cohort All Babies In Southeast Sweden study were included (n=9727). Breastfeeding duration and timing of introduction of infant formula and food were collected prospectively during the first year. Through linkage to the Swedish Patient Register, 948 children were identified with any asthma until age 15-17years, of which 450 cases were atopic. Breastfeeding duration was not associated to risk of asthma. Introduction of infant formula earlier than at 14weeks of age was associated with higher risk of non-atopic asthma. Introduction of fish before 43weeks of age, as compared to later, was associated with a lower risk of asthma, irrespective of atopic classification. Reverse causation was accounted for but did not explain the results.Conclusion: Introduction of infant formula and timing of introduction of fish seem to impact the long-term risk of doctor-diagnosed asthma. Emphasis on the growing body of evidence that early introduction of allergens offers protection against atopic disease should be considered in future recommendations.Funding Agencies|Swedish Child Diabetes Foundation (Barndiabetesfonden); Novo Nordisk Foundation; Research Council of South-east Sweden (FORSS); Swedish Research Council [K2005-72X-11242-11A]; ALF/County Council of Ostergotland</p
Introduction of complementary foods in Sweden and impact of maternal education on feeding practices.
OBJECTIVE: To describe the introduction of complementary foods in a population-based cohort in relation to recommendations and explore the possible impact of maternal education on infant feeding practices. DESIGN: Prospective data from the All Babies in Southeast Sweden (ABIS) cohort study were used. The ABIS study invited all infants born in south-east Sweden during October 1997-October 1999 (n 21 700) to participate. A questionnaire was completed for 16 022 infants. During the infants' first year parents continuously filed in a diary covering introduction of foods. SETTING: Sweden. SUBJECTS: Infants (n 9727) with completed food diaries. RESULTS: Potatoes, vegetables, fruits/berries and porridge were the foods first introduced, with a median introduction between 19 and 22 weeks, followed by introduction of meat, cow's milk, follow-on formula and sour milk/yoghurt between 24 and 27 weeks. Early introduction of any food, before 16 weeks, occurred for 27 % of the infants and was more common in infants of mothers with low education. Overall, potatoes (14·7 %), vegetables (11·1 %), fruits/berries (8·5 %), porridge (7·4 %) and follow-on formula (2·7 %) were the foods most frequently introduced early. The majority of infants (≥70 %) were introduced to potatoes, vegetables, fruits/berries and porridge during concurrent breast-feeding, but introduction during concurrent breast-feeding was less common in infants of mothers with low education. CONCLUSIONS: Most infants were introduced to complementary foods timely in relation to recommendations. Low maternal education was associated with earlier introduction of complementary foods and less introduction during concurrent breast-feeding. Still, the results indicated exposure to fewer foods at 12 months in infants of mothers with low education.Funding agencies: Swedish Child Diabetes Foundation (Barndiabetesfonden); Novo Nordisk Foundation; Research Council of Southeast Sweden (FORSS); Swedish Research Council [K2005-72X-11242-11A]; ALF/County Council of Ostergotland</p
Introduction of complementary foods in Sweden and impact of maternal education on feeding practices
Metabolic risk profile among overweight and obese lactating women in Sweden.
BACKGROUND: Obesity and cardiovascular diseases are increasing globally and any association between reproduction and these conditions is of concern. Unfortunately, little is known about normal levels of metabolic risk factors in women of different body mass index throughout the reproductive cycle. This study is one of the first to describe the metabolic risk profile of lactating overweight or obese women at 8-12 weeks postpartum. METHODS: During 2007-2009, 66 overweight or obese Swedish lactating women without known diseases underwent detailed measurements of their metabolic profiles, dietary intake and general health before entering a lifestyle intervention trial. Baseline measurements took place between 8-12 wk postpartum. Almost all women were exclusively breastfeeding their term infants. RESULTS: The women were regarded as healthy, as reflected in the absence of diagnosed diseases, their own perceptions and in normal hemoglobin, albumin and fasting plasma glucose values. Four women were diagnosed with metabolic syndrome. In these cases, underlying conditions included large waist circumference, low HDL cholesterol values, high triglyceride values and relatively high blood pressure. The metabolic profile differed between overweight and obese women; obese women had significantly higher levels of fasting insulin (p = 0.017), borderline higher HOMA values (p = 0.057) and significantly higher triglyceride values (p = 0.029), as well as larger waist and hip circumferences (p<0.001 and p<0.001). However, no significant differences between overweight and obese women were detected for LDL or total cholesterol levels. Overweight and obese women reported similar total energy and macronutrient intakes, but obese women tended to be less physically active (p = 0.081). CONCLUSIONS: Among generally healthy lactating women, obesity as compared to overweight is associated with increased metabolic risk. This cut-off is thus important also in the early postpartum period, and obesity among these women should warrant proper health investigation. Macronutrient intake did not differ between the groups and, hence, cannot explain these differences. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01343238

Parity, weight change, and maternal risk of cardiovascular events
Background High parity has been suggested to increase risk of maternal cardiovascular disease independent of body mass index measured after childbearing. Pregnancy is, however, associated with persistent weight gain and metabolic changes that, independent of parity, increase the risk of cardiovascular disease. It could therefore be questioned if high parity independently increases the risk of cardiovascular disease or if this association may be confounded, mediated, or modified by other parity-related factors. Objective We sought to investigate the association between parity and risk of cardiovascular disease, and secondary outcomes in terms of myocardial infarction and cerebral infarction, with particular focus on potential mediation by anthropometric measures and effect modification by lactation. Study Design We used data from 16,515 female participants (age 44.5-73.6 years) of the population-based Malmö Diet and Cancer Study with baseline examination from 1991 through 1996. The Malmö Diet and Cancer Study was followed up throughout 2010, with a median follow-up of 15.8 years. We used Cox proportional hazards model to examine the association between parity and cardiovascular disease. Results Adjusted for age and other potential confounders, grand multiparous women (≥5 children) had an increased risk of cardiovascular disease (hazard ratio, 1.60; 95% confidence interval, 1.20–2.14), myocardial infarction (hazard ratio, 1.68; 95% confidence interval, 1.15–2.45), and cerebral infarction (hazard ratio, 1.74; 95% confidence interval, 1.18–2.58) compared to women with 2 children. Additional adjustment for baseline body mass index and weight change since age 20 years attenuated the risk, but the increased risk for cardiovascular disease (hazard ratio, 1.38; 95% confidence interval, 1.02–1.87) and myocardial infarction (hazard ratio, 1.53; 95% confidence interval, 1.04–2.26) in grand multiparous women remained significant. Models stratified by lactation time showed that risk was only raised in grand multiparous women who had a mean lactation time of <4 mo/child. In sensitivity analyses excluding women with a history of diabetes at baseline, risk estimates for grand multiparous women became nonsignificant in the full model. Conclusion Part of the increased risk of cardiovascular disease and myocardial infarction in grand multiparous women seems to be mediated by weight gain and potentially by higher likelihood of type 2 diabetes mellitus. Lactation may modify the increased risk of grand multiparity in that longer duration might offset the cardiovascular disease risk
Cost-effectiveness and quality of life of a diet intervention postpartum: 2-year results from a randomized controlled trial
Background
Pregnancy has been identified as a contributor to obesity. We have shown that a diet intervention postpartum produced a 2-y weight loss of 8%. Here, we present the impact of the diet intervention on cost-effectiveness and explore changes in quality of life (QOL).
Methods
A total of 110 postpartum women with overweight/obesity were randomly assigned to diet (D-group) or control (C-group). D-group received a 12-wk diet intervention within primary health care followed by monthly emails up to the 1-y follow-up. C-group received a brochure. Changes in QOL were measured using the 36-item Short Form Health Survey and EQ-5D. The analysis of cost-effectiveness was a cost-utility analysis with a health care perspective and included costs of intervention for stakeholder, quality-adjusted life-years (QALYs) gained and savings in health care. The likelihood of cost-effectiveness was examined using the net monetary benefit method.
Results
The D-group increased their QOL more than the C-group at 12 wk. and 1 y, with pronounced differences for the dimensions general health and mental health, and the mental component summary score (all p < 0.05). Cost per gained QALY was 1704–7889 USD. The likelihood for cost-effectiveness, based on a willingness to pay 50,000 USD per QALY, was 0.77–1.00.
Conclusions
A diet intervention that produced clinically relevant postpartum weight loss also resulted in increased QOL and was cost-effective.
