Childhood and Adulthood Passive Smoking and Nonalcoholic Fatty Liver in Midlife: A 31-year Cohort Study.

INTRODUCTION: Identifying early life risk factors remains key to the prevention of nonalcoholic fatty liver (hereinafter "fatty liver") in adulthood. However, the longitudinal association of childhood passive smoking with adult fatty liver is not studied. We examined the association of childhood and adulthood passive smoking with fatty liver in midlife. METHODS: This was a 31-year prospective cohort study of 1,315 participants. Information on childhood passive smoking (parental smoking) was collected in 1980 (aged 3-18 years) and 1983 and adulthood passive smoking in 2001, 2007, and 2011. Fatty liver was determined by ultrasound in 2011 (aged 34-49 years). RESULTS: The prevalence of fatty liver was 16.3%. Both childhood and adulthood passive smoking were associated with higher risk of fatty liver, adjusting for potential confounders such as age, sex, childhood socioeconomic status, and adulthood physical activity and alcohol consumption (relative risk = 1.41, 95% confidence interval: 1.01-1.97 for childhood; 1.35, 1.01-1.82 for adulthood). Individuals with persistent exposure to passive smoking between childhood and adulthood had the highest risk (relative risk = 1.99, 95% confidence interval: 1.14-3.45) compared with those without passive smoking in either childhood or adulthood. DISCUSSION: Passive smoking in both child and adult lives are associated with increased risk of adult fatty liver, suggesting that the prevention of passive smoking should start as early as possible and maintain throughout lifetime.

Temperament profiles are associated with dietary behavior from childhood to adulthood.

BACKGROUND AND OBJECTIVES: Temperament may be associated with eating behaviors over the lifespan. This study examined the association of toddlerhood temperament with dietary behavior and dietary intervention outcomes across 18 years. METHODS: The study comprised 660 children (52% boys) from The Special Turku Intervention Project (STRIP), which is a longitudinal randomized controlled trial from the age of 7 months until the age of 20 years (1990-2010). Temperament was assessed using Carey temperament scales when the participants were 2 years of age. Latent profile analysis yielded three temperament groups, which were called negative/low regulation (19% of the children), neutral/average regulation (52%) and positive/high regulation (28%). Dietary behavior was examined from 2 to 20 years of age using food records, which were converted into a diet score (mean = 15.7, SD 4.6). Mixed random-intercept growth curve analysis was the main analytic method. RESULTS: Dietary behavior showed a significant quadratic U-shaped curve over time (B for quadratic association = 0.39, P<.001; B for linear association = 0.09, P = 0.58). Children in the negative/low regulation temperament group had a lower diet score (less healthy diet) across the 18 years compared to children in the neutral/average or in the positive/high regulation group. Temperament was not associated with the rate of change in diet over time. Temperament did not have any interactive effects with the intervention (F [2, 627], P = 0.72). CONCLUSION: Children with a temperament profile characterized by high negative mood, high irregularity and high intensity in emotion expression constitute a risk group for less healthy eating over the lifespan.

Effects of intramuscular vatinoxan (MK-467), co-administered with medetomidine and butorphanol, on cardiopulmonary and anaesthetic effects of intravenous ketamine in dogs.

OBJECTIVE: To investigate the impact of intramuscular (IM) co-administration of the peripheral α2-adrenoceptor agonist vatinoxan (MK-467) with medetomidine and butorphanol prior to intravenous (IV) ketamine on the cardiopulmonary and anaesthetic effects in dogs, followed by atipamezole reversal. STUDY DESIGN: Randomized, masked crossover study. ANIMALS: A total of eight purpose-bred Beagle dogs aged 3 years. METHODS: Each dog was instrumented and administered two treatments 2 weeks apart: medetomidine (20 µg kg-1) and butorphanol (100 µg kg-1) premedication with vatinoxan (500 µg kg-1; treatment MVB) or without vatinoxan (treatment MB) IM 20 minutes before IV ketamine (4 mg kg-1). Atipamezole (100 µg kg-1) was administered IM 60 minutes after ketamine. Heart rate (HR), mean arterial (MAP) and central venous (CVP) pressures and cardiac output (CO) were measured; cardiac (CI) and systemic vascular resistance (SVRI) indices were calculated before and 10 minutes after MVB or MB, and 10, 25, 40, 55, 70 and 100 minutes after ketamine. Data were analysed with repeated measures analysis of covariance models. A p-value <0.05 was considered statistically significant. Sedation, induction, intubation and recovery scores were assessed. RESULTS: At most time points, HR and CI were significantly higher, and SVRI and CVP significantly lower with MVB than with MB. With both treatments, SVRI and MAP decreased after ketamine, whereas HR and CI increased. MAP was significantly lower with MVB than with MB; mild hypotension (57-59 mmHg) was recorded in two dogs with MVB prior to atipamezole administration. Sedation, induction, intubation and recovery scores were not different between treatments, but intolerance to the endotracheal tube was observed earlier with MVB. CONCLUSIONS AND CLINICAL RELEVANCE: Haemodynamic performance was improved by vatinoxan co-administration with medetomidine-butorphanol, before and after ketamine administration. However, vatinoxan was associated with mild hypotension after ketamine with the dose used in this study. Vatinoxan shortened the duration of anaesthesia.

Association of Adiponectin with Adolescent Cardiovascular Health in a Dietary Intervention Study.

OBJECTIVE: To investigate whether an infancy-onset, low saturated fat-oriented dietary intervention influences serum adiponectin concentration in adolescents, and to study the association of adiponectin with subclinical markers of vascular health, and cardio-metabolic risk factors. STUDY DESIGN: The longitudinal, randomized Special Turku Coronary Risk Factor Intervention Project aimed to modify child's dietary fat quality replacing saturated fat with unsaturated fat. Serum adiponectin (n = 521) along with weight, height, high-density lipoprotein cholesterol, C-reactive protein (CRP), triglycerides, and insulin were measured at age 15 years. Adiposity was assessed using body mass index, waist circumference, and abdominal fat thickness measured with ultrasound. Metabolic syndrome was defined according to International Diabetes Foundation criteria. Vascular ultrasound measures including carotid intima-media thickness (IMT) were assessed. RESULTS: Adiponectin concentrations were similar in the intervention and control groups (P = .16). Adiponectin associated with carotid IMT (r = -0.13, P = .005), high-density lipoprotein cholesterol (r = 0.18, P < .0001), triglycerides (r = -0.16, P = .0004), CRP (r = -0.10, P = .02), insulin (r = -0.14, P = .002), and adiposity (r = -0.18-0.24, P ≤ .0001). When adjusted for adiposity indices, the association with carotid IMT was only marginally diluted (P = .03-.06), but the associations with insulin and CRP became nonsignificant. Adolescents with adiponectin ≤median had 4-fold risk of metabolic syndrome than peers with adiponectin >median (CI 1.8-10.2, P = .0001). CONCLUSIONS: In healthy adolescents, low serum adiponectin is related with carotid IMT and metabolic syndrome. We found no evidence that repeated low saturated fat-oriented dietary counseling would influence serum adiponectin in adolescence. TRIAL REGISTRATION: Registered with ClinicalTrials.gov: NCT00223600.

Development and evaluation of a stand-alone index for the assessment of small children's diet quality.

OBJECTIVE: To construct and evaluate an independent Children's Index of Diet Quality (CIDQ). DESIGN: A food consumption questionnaire, which contained twenty-five multiple-item questions on eating and food intake, was formulated and evaluated against 7 d food records. Key questions that best reflected a healthy diet, defined in criteria set by the nutrient recommendations, were searched and validated by correlation and analyses of receiver-operating characteristic curves. Settings A cohort of a young population of South-West Finland. SUBJECTS: Participants (n 400) were 2-6-year-old children. RESULTS: Fifteen questions were identified to best depict the children's diet quality in reference to the recommendations. These questions were scored, summarized and further constructed into a three-class index (good, moderate and poor dietary quality) where higher scores depicted better diet quality. The CIDQ cut-off score of 14 points for good dietary quality had a sensitivity of 0.59 and a specificity of 0.82 and the cut-off score of 10 points, for at least moderate dietary quality, had a sensitivity of 0.77 and a specificity of 0.69. Higher index scores were related to higher dietary intakes of several vitamins, lower dietary intakes of SFA and cholesterol, and further with lower serum cholesterol and higher serum vitamin C concentrations. CONCLUSIONS: The three-class food index was found to represent diet quality as defined in recommendations and evaluated against nutrient intakes from food diaries and biochemical markers. This self-standing index could provide an effective and low-burden method to obtain information about diet quality and guide future recommendations.

Benefits of repeated individual dietary counselling in long-term weight control in women after delivery.

As pregnancy may trigger overweight in women, new means for its prevention are being sought. The aim here was to investigate the effect of individual dietary counselling during and after pregnancy on post-partum weight and waist circumference up to 4 years post-partum. A cohort of women (n = 256) were randomized to receive repeated individual dietary counselling by a nutritionist during and after pregnancy, or as controls not receiving dietary counselling, from the first trimester of pregnancy until 6 months after delivery. Counselling aimed to bring dietary intake into line with recommendations, with particular focus on the increase in the intake of unsaturated fatty acids instead of saturated. Pre-pregnancy weight was taken from welfare clinic records. Weight and waist circumference were measured at 4 years after delivery. The proportion of overweight women increased from 26% prior to pregnancy to 30% at 4 years after delivery among women receiving dietary counselling, as against considerably more, from 32% to 57%, among controls. The prevalence of central adiposity was 31% in women receiving dietary counselling, 64% in controls. Likewise, both the risk of overweight (odds ratio: 0.23, 0.08-0.63, P = 0.005) and central adiposity (odds ratio: 0.18, 0.06-0.52, P = 0.002) were lower in women receiving dietary counselling compared with controls. Repeated dietary counselling initiated in early pregnancy can be beneficial in long-term weight control after delivery.

Childhood exposure to parental smoking and life-course overweight and central obesity.

OBJECTIVE: To evaluate the association between childhood parental smoking exposure and the risk of overweight/obesity from childhood to adulthood. METHODS: This study leverages the data from two longitudinal population based cohort studies, the Cardiovascular Risk in Young Finns Study between years 1980-2011/2012 (YFS; N = 2,303; baseline age 3-18 years) and the Special Turku Coronary Risk Factor Intervention Project between years 1989-2009/2010 (STRIP; N = 632; baseline age 7 months). Weight, height and waist circumference were measured from childhood to adulthood. Overweight/obesity was defined as body mass index ≥25 kg/m2 in adults and using the Cole criteria in children. Central obesity was defined as waist circumference > 100/90 cm in men/women and as a waist-to-height ratio > 0.50 in children. Statistical analyses were adjusted for age, sex, socioeconomic status, smoking, birth weight, parental ages, diet and physical activity. RESULTS: Childhood parental smoking exposure was associated with increased risk for life-course overweight/obesity (YFS: RR1.13, 95%CI 1.02-1.24; STRIP: RR1.57, 95%CI 1.10-2.26) and central obesity (YFS: RR1.18, 95%CI 1.01-1.38; STRIP: RR1.45, 95%CI 0.98-2.15). CONCLUSIONS: Childhood exposure to parental smoking is associated with increased risk of overweight/obesity over the life-course. KEY MESSAGES Exposure to parental smoking in childhood was associated with increased risk of overweight/obesity, central obesity and adiposity measured by skinfold thickness from childhood to adulthood.

Longitudinal effect of 20-year infancy-onset dietary intervention on food consumption and nutrient intake: the randomized controlled STRIP study.

BACKGROUND/OBJECTIVES: Coronary heart disease begins in childhood and warrants prevention strategies such as dietary modification. The objective was to determine the effect of the Special Turku Coronary Risk Factor Intervention Project (STRIP) dietary intervention on food consumption and nutrient intake over 20-year intervention period. SUBJECTS/METHODS: The STRIP is a prospective, randomized trial conducted between 1990 and 2011. Enrolled 6-month-old infants (n = 1062) were randomized to an intervention group (n = 540) receiving dietary counseling biannually from age 7 months to 20 years or control group (n = 522) not receiving any intervention. Food and nutrient intake was assessed annually using 4-day food records. A food-based diet score was calculated. RESULTS: The intervention led to (1) higher consumption of low-fat unsweetened dairy (ß = 177.76, 95% CI 157.36-198.16 g/day), vegetable-oil based fats (ß = 6.00, 5.37-6.63 g/day), fish (ß = 2.45, 1.44-3.45 g/day), fiber-rich grain products (ß = 5.53, 3.17-7.89 g/day), fruits/berries (ß = 9.93, 4.44-15.43 g/day), vegetables (ß = 11.95, 7.74-16.16 g/day); (2) lower consumption of desserts (ß = - 4.10, 95% CI - 6.50 to - 1.70 g/day); (3) lower intake of sucrose (ß = - 1.61, 95% CI - 2.88 to - 0.35 g/day), and higher intake of fiber (ß = 0.83, 0.55-1.11 g/day), folate (ß = 11.14, 95% CI 8.23-14.05 µg/day), vitamin D (ß = 0.52, 0.39-0.64 µg/day), C (ß = 8.08, 4.79-11.38 mg/day), E (ß = 0.93, 0.81-1.05 mg/day), iron (ß = 0.31, 0.18-0.44 mg/day), zinc (ß = 0.29, 0.17-0.40 mg/day), magnesium (ß = 12.17, 9.02-15.33 mg/day), sodium (ß = 55.00, 24.40-85.60 mg/day), potassium (ß = 157.11, 107.24-206.98 mg/day). No effect was found on nut/seed, red/processed meat, sugar-sweetened beverage, salty snack consumption, or vitamin A and calcium intake. Intervention effect was more pronounced in boys. CONCLUSIONS: The STRIP intervention improved children's diet quality over 20 years, indicating that beneficial dietary changes can be introduced and sustained in youth.

Longitudinal child-oriented dietary intervention: Association with parental diet and cardio-metabolic risk factors. The Special Turku Coronary Risk Factor Intervention Project.

Background The child-oriented dietary intervention given in the prospective Special Turku Coronary Risk Factor Intervention Project (STRIP) has decreased the intake of saturated fat and lowered serum cholesterol concentration in children from infancy until early adulthood. In this study, we investigated whether the uniquely long-term child-oriented intervention has affected also secondarily parental diet and cardio-metabolic risk factors. Methods The STRIP study is a longitudinal, randomized infancy-onset atherosclerosis prevention trial continued from the child's age of 8 months to 20 years. The main aim was to modify the child's diet towards reduced intake of saturated fat. Parental dietary intake assessed by a one-day food record and cardio-metabolic risk factors were analysed between the child's ages of 9-19 years. Results Saturated fat intake of parents in the intervention group was lower [mothers: 12.0 versus 13.9 daily energy (E%), p < 0.0001; fathers: 12.5 versus 13.9 E%, p < 0.0001] and polyunsaturated fat intake was higher (mothers: 6.1 versus 5.4 E%, p < 0.0001; fathers: 6.3 versus 5.9 E%, p = 0.0003) compared with the control parents. Maternal total and low-density lipoprotein cholesterol concentrations were lower in the intervention compared with the control group (mean ± SE 5.02 ± 0.04 versus 5.14 ± 0.04 mmol/l, p = 0.04 and 3.19 ± 0.04 versus 3.30 ± 0.03 mmol/l, p = 0.03, respectively). Paternal cholesterol values did not differ between the intervention and control groups. Other cardio-metabolic risk factors were similar in the study groups. Conclusions Child-oriented dietary intervention shifted the dietary fat intakes of parents closer to the recommendations and tended to decrease total and low-density lipoprotein cholesterol in the intervention mothers. Dietary intervention directed to children benefits also parents.

Eating behavior influences diet, weight, and central obesity in women after pregnancy.

OBJECTIVE: The aim of this study was to explore whether type of eating behavior is related to diet and overweight in women after childbirth. METHODS: In a prospective mother-infant study, women's (N = 189) eating behavior, dietary intake from food diaries, weight, and waist circumference (WC) were measured at 6, 12, 24, and 48 mo after giving birth. Three aspects of eating behavior were measured by the validated Three Factor Eating Questionnaire-18: cognitive restraint (CR; restricting of eating without associated hunger or fullness), emotional eating (EE; overeating due to negative feelings), and uncontrolled eating (UE; overeating irrespective of physiologic need). RESULTS: High scores in CR associated with the lowest tertile of fat intake (% of energy [E%], P = 0.045). High UE scores associated with the highest tertiles of intakes of energy (kcal; P < 0.001), fiber (g; P < 0.001) and sucrose (E%; P < 0.001). High EE scores (P = 0.003) linked with overweight (body mass index ≥ 25 kg/m(2)), whereas UE (P < 0.001) linked with central obesity (WC ≥ 80 cm). CONCLUSIONS: We demonstrated that certain types of eating behavior related to both energy-dense diet and weight and central adiposity. We propose that measuring eating behavior by the simple questionnaire could be a helpful tool in dietary counseling that aids in identifying women who are likely at risk for unhealthy dietary patterns and for developing overweight.
