Most IDDM patients temporarily restore some of their beta-cell function following the initiation of insulin therapy. The aim of this study was to analyse the influence of age, gender, metabolic state at diagnosis and presence of autoantibodies (GAD65 antibodies and IC A) on the duration of the clinical partial remission. In total, 149 consecutively diagnosed IDDM children, 0–16 y old (70F, 79M, mean age 9. 5 y) were studied. Partial remission was arbitrarily defined as the period when the insulin dose was below 0. 5 U/BW 24h-1 and HbA1c below 7. 5%, and occurred in 119/149 patients with a duration between 1 and 38 months. Cox's regression analysis showed that the factors significantly associated with the duration of remission were age, gender, interaction between age and gender, ICA and a high initial HbAlc, whereas GAD65Ab had no influence. Young boys had the shortest remission period, while adolescent boys had the longest, as compared to young and adolescent girls. The IC A-negative patients ( n = 42) had a longer remission period (median 9. 7 months) than the ICA-positive children ( n = 107; 5. 0 months; p = 0. 0001), regardless of GAD65Ab status. We speculate that the relative insulin resistance, which is more pronounced in pubertal girls than in boys, may be associated with a more rapid increase of exogenous insulin requirement. These findings are important when evaluating the effect of islet cell autoreactivity on the clinical course of IDDM in children.  相似文献

The initial psychological reactions at the onset of insulin-dependent diabetes mellitus (IDDM) in a population-based sample of 76 children were studied with staff observations and a self-report questionnaire for children 12 years of age and more. Younger children reacted with more anger and less distress than the older children. High initial self-reported distress was associated with poorer subjective psychological IDDM adjustment at a follow-up 10 months later for the older children. The children's initial reactions as well as later adjustment were intimately associated with maternal initial reactions in the total group. The metabolic control, estimated as the mean level of the major fraction of glycosylated haemoglobin (Hb AIc) during the first 2 years, was poorer in the adolescent group. Initial anxiety over injections and protest but low general distress in mothers and children were associated with better metabolic control.  相似文献

Objective: To evaluate self and parent reports on quality of life (QoL) and psychological adjustment of youths with type 1 diabetes, in comparison to a general paediatric population, and identify relationships between disease duration, metabolic control and psychological parameters. Research design and methods: Participants included 70 youths with type 1 diabetes and their parents. They were compared with 70 non‐diabetic subjects. Data were analyzed in the whole group and in subgroups aged 6–10, 11–13 and 14–18 yr. All cases performed pediatric QoL, Child Behaviour Checklist, filled in by parents, and Youth Self‐Report, filled in by youths. Data were compared with haemoglobin A1c (HbA1c) values and disease duration. Results: Self‐reports showed a psychological adjustment of youths with type 1 diabetes similar to that of controls. Parent reports showed that parents of children with type 1 diabetes were more worried than those of controls (p < 0.01). Adolescents showed a worse QoL and more frequent psychological disturbances. In this group, for youth and parent reports, HbA1c levels correlated positively with psychological problems (p < 0.05) and negatively with QoL (p < 0.05). Only for parent reports, in the whole group and in subgroups aged 6–10 and 11–13 yr, disease duration correlated positively with psychological adjustment (p < 0.05). Conclusions: Before adolescence, youths with type 1 diabetes showed only slight problems in psychological adjustment and QoL, with an association with disease duration reported by parents. In adolescence, both youths and their parents reported more emotional and behavioural problems, independent of disease duration. Better metabolic control and psychological well‐being seemed directly related.  相似文献

AIM: To study the prevalence of behavioural and emotional problems among children from different family types, sibship size and birth order. METHODS: A prospective birth cohort (n = 9357) study where parents filled in two questionnaires and teachers assessed children's behaviour using the Rutter scale (RB2). RESULTS: 14.3% scored above the cut-off point (RB2 > or = 9) indicating probable psychiatric disturbance, boys more often than girls (OR 2.6, 95% CI 2.3-3.0). Behavioural problems (9.2%) were more common than emotional ones (4.1%). Boys living in families other than two-parent families were at risk for probable psychiatric disturbance, and a corresponding risk was observed for girls living in single-parent or always one-parent families. Other than two-parent family was also a risk for behavioural problems; for boys adjusted odds ratios ranged significantly from 1.8 to 2.4 and for girls from 2.0 to 3.7. "Only children" had the highest prevalence of behavioural problems, while children in very large families had the lowest. Living in a very large family was a protective factor against behavioural problems among boys but not among girls. Eldest children were at lower risk of behavioural problems than the other children. The single-parent and always one-parent family was associated with higher risk of emotional problems among girls. CONCLUSION: Children's psychiatric problems are manifested at school mostly as behavioural problems. A two-parent family and being the oldest in the sibling series seem to be protective factors. Very large family size, if not connected to social disadvantages, does not seem to be a risk factor for children's behaviour.  相似文献

Aim: In this population‐based study, we aimed to determine the total sleep duration (TSD), its association with socio‐economic status (SES) and behavioural symptoms among schoolchildren. Methods: A cross‐sectional study was performed among schoolchildren in Istanbul. A structured questionnaire evaluating the sleep schedule variables was filled out by their parents. SES was determined according to the Turkish SES scale. Results:  The mean age of 2669 children was 8.2 ± 2.4 years, and 51% of the students were girls. The mean TSD was 10.20 ± 1.04, and the mean bedtime was 21.57 ± 0.56 (both in hours, minutes ± SD). Boys tended to go bed later (p = 0.004) and slept less than girls (p = 0.02). The duration of sleep disruptions increased (p < 0.001), whereas TSD decreased with age (p < 0.001). Multiple linear regression revealed that waking time and TSD decreased significantly (p < 0.05) with higher SES among both girls and boys. Sleep fragmentation was associated with habitual snoring, parasomnias, daytime sleepiness and conduct symptoms. Conclusion: Decreased total sleep duration is more prominent in boys, older children and children among higher socio‐economic status. Insufficient sleep attributed to shortened total sleep duration by age and higher socio‐economic status might have a negative effect on both sleep hygiene and psychological well‐being in schoolchildren.  相似文献

ABSTRACT. We studied 178 diabetic children and adolescents diagnosed during the period 1962-79 to find out the occurrence and duration of the postinitial remission, factors favoring a remission and the prognostic value of the remission. A postinitial remission occurred in 113 children (64 %) being complete in only three boys (2 %). The duration ranged from one month to 4.8 years, the mean being 8.4 months. The boys had a remission more often and of longer duration than the girls. The duration of diabetes was longer in the children without remission. The children with remission had lower blood glucose, milder hyperketonemia and ketonuria, higher pH and Pco2 at onset than those without remission. Hemoglobin A1 (HbA1) during 1979 were lower in the children with a positive remission history. The children with a remission lasting more than one year had a subsequently higher glucosuria index, lower HbA1 and higher C-peptide when compared to those without remission or to those with a short remission. The remission frequency increased from 1962 to 1979. Male sex and mild metabolic derangement at onset favor a postinitial remission, which results in a persisting residual beta-cell function and better metabolic control beyond the remission.  相似文献

ABSTRACT. Cord blood IgE (CB-IgE) is widely used as a screening parameter for atopy. Therefore it is necessary to define the normal values accurately. In this study influence of sex and gestational age on CB-IgE is evaluated. 5305 cord blood samples were analysed. Boys had a higher CB-IgE than girls ( p <0.001). Using a cut-off value for normal of 2.4 μg/11, boys had significantly more abnormal values than girls ( p =0.0475). Using a lower cut-off value (2.16, 1.92, 1.68 μg/ l) the difference became more significant ( p =0.0029, p =0.0036 and p =0.0019 respectively). Gestational age (in the range from 34–42 weeks of gestation) had no influence on the absolute CB-IgE concentration nor on the number of abnormal values. From this study we may conclude that, when CB-IgE is used in prediction and prevention programs for atopic disease, the sex of the newborn should be taken into consideration when evaluating the results, in particular when the cut-off limit is lowered. No correction needs to be made for gestational age if the baby is bom after the 34th week of gestation.  相似文献

The aim of this study was to evaluate the dietary iron intake of 15-year-old adolescents from two different regions of Sweden, in relation to their iron status. The study comprised 185 boys and 209 girls, randomly selected from the official population register. The iron intake was calculated from a 7-day record, and varied between 7 and 35 and 6 and 27 mg per day for boys and girls, respectively. The daily median intakes in boys and girls were 18.7 and 14.2 mg, respectively. S-ferritin, s-iron, and s-transferrin saturation, measured in all the subjects, did not differ significantly between the two regions. However, the mean serum ferritin concentration was significantly higher in the boys (36.4μgl-1) than in the girls (29.4μgl-1)( p < 0.001). Low s-ferritin levels, defined as s-ferritin < 12 μgl-1 were found in seven boys (3.7%) and in 29 girls (13.9%). None of the adolescents had iron deficiency anaemia, defined as Hb< 110gl-1 in combination with s-ferritin < 12μgl-1. Regression and correlation analyses did not show any significant correlation between dietary iron intake and s-ferritin, or between s-ferritin and haemoglobin (Hb), MCH and MCHC. A significant correlation was found, however, between s-ferritin and transferrin saturation ( p < 0.005) in both sexes. When the adolescents who still had s-ferritin < 12μgl-1 at a second blood examination were given a 6 weeks trial with oral iron therapy, all of them showed an increase both in s-ferritin and in blood Hb. The 95% confidence intervals of s-ferritin for 15-year-old Swedish boys and girls were defined as 11-90 and 7 85 μ.gl-1, respectively.  相似文献

OBJECTIVES: To determine the extent to which childhood short stature is associated with cognitive, behavioural and chronic health problems, and whether these problems could be attributed to recognized adverse biological, psychosocial or psychological factors. METHODOLOGY: At their first antenatal session, 8556 women were enrolled in a prospective study of pregnancy. When their children were 4 and 6 years of age, mothers completed a detailed questionnaire concerning their child's health and behaviour. A Peabody Picture Vocabulary Test-Revised (PPVT-R) was completed by the child at 5 years of age. Z scores were used to categorize height measurements in 3986 children. The relationship of these height categories with the child's health, and behavioural and cognitive problems was then examined. RESULTS: No association was found between height and symptoms of chronic disease or behaviour problems in boys or girls. On the unadjusted analysis, mean PPVT-R scores were significantly lower in boys with heights < 3 percentile and 3-< 10 percentile compared with study children between 10 to 90 percentile (P < 0.01). Scores were similarly significantly lower in girls with heights < 3 percentile and 3-10 percentile (P = 0.01). Even after adjusting for psychosocial and biological confounders, short stature remained a significant predictor for lower PPVT-R scores in both boys and girls, although height only accounted for 1.1% of the variance in scores in boys and 0.5% of the variance in PPVT-R scores in girls. Psychosocial factors had a greater role than height in determining PPVT-R scores at 5 years of age. CONCLUSIONS: These findings suggest a significant, though small, association between height and PPVT-R scores at 5 years of age, independent of psychosocial disadvantage and known biological risk factors.  相似文献

We analysed the body growth of 121 prepubertal children with polycystic kidney disease participating in a longitudinal multicentre study. The patients were followed from an age of 1 to 9 years in girls and 1 to 10 years in boys over a mean period of 3.6 years. Children with end-stage renal disease were excluded. Fifty-four patients had the autosomal dominant form of the disease and 67 the autosomal recessive form. At last observation, 2% of patients with the dominant form and 28% of those with the recessive form had an estimated glomerular filtration rate of < 60 ml/(min 1.73 m2). At first observation, the mean height SD score (SDS) in patients with the dominant form was almost the same as in controls, whilst in those with the recessive form it was significantly decreased (girls –0.82 SDS, boys -0.68 SDS, p < 0.001). During the follow-up the height SDS decreased slightly in both groups (NS). In patients with autosomal recessive kidney disease the degree of growth retardation appeared to be related to renal function: at last observation the height of girls with an estimated glomerular filtration rate of < 60ml/(min 1.73 m2) was more retarded than that of boys (mean -2.1 SDS versus -1.5 SDS, NS). The height SDS and renal function at last observation correlated in girls ( r = 0.83, p < 0.001) but not in boys ( r = 0.55) with the recessive form. No correlation was found between the height SDS and hypertension. The weight-for-height SDS at onset was significantly reduced in patients with the recessive form with decreased renal function. Our data suggest that the autosomal recessive, but not the dominant, form of polycystic kidney disease is associated with early growth retardation, which seems to be more severe in girls, probably due to the more rapid deterioration of renal function.  相似文献

Personality and behavioural characteristics of a population-based cohort of 29 very low-birth-weight (VLBW) infants were compared with those of 29 matched, term controls at eight years of age. The VLBW infants were born to families of lower socioeconomic status (p = 0.04) and had a lower mean IQ (93 versus 104, p = 0.008) and motor abilities (p = 0.028). Based on the questionnaire personality inventory for children, the VLBW children had more learning difficulties and school coping problems, and the VLBW boys had more conduct and emotional problems than the controls. Except for conduct problems, these differences persisted after controlling for socioeconomic status. Generally, there were significant relationships between behaviour, IQ and motor abilities. In conclusion, VLBW may be a risk factor for the development of school coping and behavioural problems independent of socioeconomic status but often coexist with impaired cognitive and neuromotor function.  相似文献

In a population based study, the prescribed insulin dose of 348 prepubertal children with insulin-dependent diabetes mellitus (IDDM) was analysed 2 years after the diagnosis of diabetes. Girls had an insulin dose 13.6% higher than that in boys. When children younger than 5 years of age at diagnosis were analysed separately, the difference in insulin dose between boys and girls remained. The increased insulin dose in girls was not explained by possible differences in endogenous insulin secretion, body mass index, metabolic control or the number of daily insulin injections. Our observations indicate that prepubertal girls with IDDM have a poorer insulin sensitivity than boys. Received: 26 May 1997 / Accepted in revised form: 26 January 1998  相似文献

The social, behavioural, and school adjustment of 41 9-year-old children in long-term residential group care in Greece was compared with that of children of the same sex and age brought up in two-parent families. Observational, interview, and questionnaire measures were employed. Observations in school classrooms showed that compared with their classmates, the group care children were more inattentive, participated less often in the classroom activities, were more likely to be passive, and tended to be involved in alternative and nonproductive activities. In the playground, they rarely interacted with non-institutional children. On both parent and teacher scales the group care children showed significantly more overall disturbance. The boys showed poor task involvement in the classroom and more emotional difficulties, conduct problems, and hyperactivity, whereas the between-group differences for girls were statistically significant only for emotional disturbance and poor task involvement in the classroom. Both boys and girls in long-term residential care showed less harmonious, confiding relationships with peers than those reared in families, and were more affection-seeking with teachers.  相似文献

Influence of sex and gestational age on cord blood IgE   总被引:3,自引:0,他引:3  
Cord blood IgE (CB-IgE) is widely used as a screening parameter for atopy. Therefore it is necessary to define the normal values accurately. In this study influence of sex and gestational age on CB-IgE is evaluated. 5,305 cord blood samples were analysed. Boys had a higher CB-IgE than girls (p less than 0.001). Using a cut-off value for normal of 2.4 micrograms/l, boys had significantly more abnormal values than girls (p = 0.0475). Using a lower cut-off value (2.16, 1.92, 1.68 micrograms/l) the difference became more significant (p = 0.0029, p = 0.0036 and p = 0.0019 respectively). Gestational age (in the range from 34-42 weeks of gestation) had no influence on the absolute CB-IgE concentration nor on the number of abnormal values. From this study we may conclude that, when CB-IgE is used in prediction and prevention programs for atopic disease, the sex of the newborn should be taken into consideration when evaluating the results, in particular when the cut-off limit is lowered. No correction needs to be made for gestational age if the baby is born after the 34th week of gestation.  相似文献

OBJECTIVE: To determine the differences in short term outcome of very low birthweight infants attributable to sex. METHODS: Boys and girls weighing 501-1500 g admitted to the 12 centres of the National Institute of Child Health and Human Development Neonatal Research Network were compared. Maternal information and perinatal data were collected from hospital records. Infant outcome was recorded at discharge, at 120 days of age if the infant was still in hospital, or at death. Best obstetric estimate based on the last menstrual period, standard obstetric factors, and ultrasound were used to assign gestational age in completed weeks. Data were collected on a cohort that included 3356 boys and 3382 girls, representing all inborn births from 1 May 1991 to 31 December 1993. RESULTS: Mortality for boys was 22% and that for girls 15%. The prenatal and perinatal data indicate few differences between the sex groups, except that boys were less likely to have been exposed to antenatal steroids (odds ratio (OR) = 0.80) and were less stable after birth, as reflected in a higher percentage with lower Apgar scores at one and five minutes and the need for physical and pharmacological assistance. In particular, boys were more likely to have been intubated (OR = 1.16) and to have received resuscitation medication (OR = 1.40). Boys had a higher risk (OR > 1.00) for most adverse neonatal outcomes. Although pulmonary morbidity predominated, intracranial haemorrhage and urinary tract infection were also more common. CONCLUSIONS: Relative differences in short term morbidity and mortality persist between the sexes.  相似文献

A better understanding of the remission phase, while residual beta-cell function is still present in recently diagnosed type 1 (insulin dependent) diabetes mellitus (IDDM), is very important because of the potential for pharmacological intervention to preserve this function. To evaluate the natural course and characteristics of the remission phase in children and adolescents with IDDM, a retrospective study was performed on patients diagnosed with IDDM under the age of 18 years during the years 1991-1998. Sixty-two patients whose medical records were available were included in the study. Data were collected by reviewing the hospital records of patients from the time of diagnosis through the first 24 months after diagnosis. The duration of symptoms and history of infection prior to presentation, diabetic ketoacidosis (DKA) at diagnosis, length of hospitalization, initial glucose level, basal C-peptide levels at diagnosis, daily insulin requirements per kg body weight and HbA1c at diagnosis and at each visit were recorded. Thirty-five patients (56.5%) entered partial remission. We observed similar remission rates in those aged <10 and > or =10 years at diagnosis and in boys and girls. History of infection and presentation with DKA were associated with a lower rate of remission (p<0.001, p<0.0001, respectively) and were more commonly observed under the age of 10 years (p<0.0001, p<0.0001, respectively). The average insulin requirements per kg body weight calculated at diagnosis decreased with increasing age (r = -0.31, p = 0.012). The length of time until remission was 1.36+/-1.03 (mean +/- SD) months and positively correlated with insulin requirements at discharge from the hospital (r = 0.63, p<0.0001). Mean duration of remission was 11.67+/-5.82 months and was much longer in boys than girls (p<0.05). Six patients, all boys, entered total remission for 3.80+/-3.73 months. HbA1c concentrations in the first year of the disease were significantly lower in patients who underwent a remission phase (7.31+/-1.24% vs. 8.24+/-1.47%, p <0.05). However, this difference was not observed during the second year of the disease. In conclusion, history of infection prior to presentation and DKA at diagnosis were associated with young age and were the most important factors negatively influencing the remission rate in newly diagnosed IDDM patients.  相似文献

Background: Empathy dysfunction is one of the hallmarks of psychopathy, but it is also sometimes thought to characterise autism spectrum disorders (ASD). Individuals with either condition can appear uncaring towards others. This study set out to compare and contrast directly boys with psychopathic tendencies and boys with ASD on tasks assessing aspects of affective empathy and cognitive perspective taking. The main aim of the study was to assess whether a distinct profile of empathy deficits would emerge for boys with psychopathic tendencies and ASD, and whether empathy deficits would be associated with conduct problems in general, rather than psychopathic tendencies or ASD specifically. Methods: Four groups of boys aged between 9 and 16 years (N = 96) were compared: 1) psychopathic tendencies, 2) ASD, 3) conduct problems and 4) comparison. Tasks were included to probe attribution of emotions to self, empathy for victims of aggression and cognitive perspective‐taking ability. Results: Boys with psychopathic tendencies had a profile consistent with dysfunctional affective empathy. They reported experiencing less fear and less empathy for victims of aggression than comparison boys. Their cognitive perspective‐taking abilities were not statistically significantly different from those of comparison boys. In contrast, boys with ASD had difficulties with tasks requiring cognitive perspective taking, but reported emotional experiences and victim empathy that were in line with comparison boys. Boys with conduct problems did not differ from comparison boys, suggesting that the affective empathy deficit seen in boys with psychopathic tendencies was specific to that group, rather than common to all boys with conduct problems. Conclusions: Although both groups can appear uncaring, our findings suggest that the affective/information processing correlates of psychopathic tendencies and ASD are quite different. Psychopathic tendencies are associated with difficulties in resonating with other people’s distress, whereas ASD is characterised by difficulties in knowing what other people think.  相似文献

ABSTRACT. The metabolic control, assessed from the mean daily glucosuria, mean daily glucosuria index based on home tests, and mean haemoglobin A1 (HbA1) concentrations during 1980, and the influence of various factors on the control were analysed in 177 diabetic children and adolescents. The mean daily glucosuria was 21 % of the carbohydrates in the subscribed diet, and the mean glucosuria index 55 %. The mean HbA] was 14.0 %. Boys had better metabolic control than girls. Good motivation towards treatment was associated with better metabolic control. There was a negative correlation between metabolic control and both the age of the child and the duration of diabetes. Prepubertal children were better controlled than those in puberty. Adherence to the dietary regimen was related to better control, as was the patient's endogenous insulin secretion, measured by serum C-peptide concentration. There was also an association between the season and the metabolic control, the control being better in the spring than during the other seasons. On the basis of these results male sex, a good motivation towards treatment, residual beta-cell function and adherence to the prescribed diet favor good metabolic control, while a long duration of the disease, the presence of puberty and relatively high age in childhood are factors impairing the metabolic control.  相似文献

A cross-sectional study of health and adjustment among 18 to 22-year-old patients with insulin-dependent diabetes mellitus (IDDM) is reported. Objectives were to examine coping with IDDM in this age group; to identify predictors of health status, treatment adherence, and health care use; and to provide a retrospective evaluation of the persistence of IDDM-specific adjustment from earlier through later adolescence. Multiple validated measures, interviews of independent informants, and biochemical assays were used to assess psychological, behavioral, and metabolic status. Patients and parents completed a retrospective measure of the patient's adjustment to IDDM during earlier adolescence. Findings (n = 81) indicated: (1) normal rates of general psychopathology but some evidence of poorer adjustment to IDDM relative to other age groups, (2) poor diabetic control and high incidence of microalbuminuria, (3) specific factors associated differentially with treatment compliance, health care use, diabetic control, and microalbuminuria among late adolescents, and (4) evidence that poor adjustment to IDDM in earlier adolescence persists into the transition to adulthood. The findings imply that late adolescents with IDDM are at risk of various unfavorable behavioral and health outcomes and that adjustment to the disease during earlier adolescence may be a predictor of subsequent health-related behavior and health status. A longitudinal study is needed to confirm these findings.  相似文献

This study was conducted to assess the prevalence of anemia among preschool children (3-5 years) and its association with malnutrition in rural Barabanki district of Uttar Pradesh, India. Three out of 18 sub-centers in Nindura block, Barabanki, each with six villages, were randomly selected for this survey and 654 boys and 546 girls were included. Mean hemoglobin level in g/dL among boys and girls was 10.1 (SD: 1.66) and 9.9 (SD: 1.67) (P <0.06) respectively. The proportion of anemic children (Hb <11 g/dL) was 70%. Boys were heavier and taller as compared to girls. Among the 67.3% underweight children the mean hemoglobin level was 9.85 (SD: 1.67) as compared to 10.39 (SD: 1.62) in those without malnutrition (P <0.0001). Likewise, stunted children (87.6%) had statistically significantly lower mean hemoglobin levels than those not stunted. The odds ratio of an underweight and stunted child having moderate to severe anemia was 1.66. While more than half caretakers knew about the term "anemia " and associated physical weakness with it, only very few (2.5%) knew that iron intake will improve it. They relied on "doctors" (86.7%) for anemia prevention.  相似文献
