Abstract
OBJECTIVES Despite the high prevalence of children with sickle cell anaemia (SCA) in West Africa, there is paucity of data on the height velocity and prevalence of growth failure in SCA patients. With advances in clinical care of SCA patients, could there be a spatial and secular trend in the growth pattern of these children? Hence, the compelling needs to embark on this study. The objectives of the study were to determine the prevalence of growth failure among patients with SCA and its correlation with age, gender and age at diagnosis. METHODS A Prospective longitudinal study of a cohort of sickle cell anaemic paediatric patients from Pediatrics SCA Clinic, University of Nigeria Teaching Hospital, Ituku Ozalla. Patients were enrolled over a period of two years using a non-parametric convenient sampling method. Their heights were measured at baseline, three months, six months and at 12 months intervals and subsequently plotted on a standard WHO growth chart. The height velocities at different monthly intervals were calculated and compared with the WHO standard normal linear growth rates) for children (used as control) to identify those with GF. (i.e. <10th percentile). The main outcome measures were the mean height velocities at different months' intervals calculated and compared using the repeated measurement analysis of variance (ANOVA) and the Wilcoxon signed test. RESULTS A cohort of 316 children aged 1-18 years with SCA was evaluated with a male preponderance of 161 (57.4%). The mean age and age at diagnosis were 11.04 ± 5.56 and 4.2 ± 1.7 years, respectively. The prevalence of growth failure and short stature was 84.7%. The burden of GF was highest among post-pubertal participants (94.1%). The most important predictor of growth velocity deficit was age (R2=0.045, standard β coefficient = -0.22, t=-03.51, p=0.001). CONCLUSIONS The study demonstrated high prevalence of growth failure in children and adolescents with SCA which intensified with advancement in age and older age at diagnosis.

Abstract
Growth failure (GF) in children with sickle cell disease (SCD) tends to decline in high-income countries, but data are lacking in sub-Saharan Africa. We performed a cross-sectional study nested in the CADRE (Cœur, Artères et DREpanocytose) cohort in Mali, Senegal, Cameroon, Gabon and the Ivory Coast. SCD patients and healthy controls aged 5-21 years old were recruited (n = 2583). Frequency of GF, defined as a height, weight or body mass index below the 5th percentile on World health Organization growth charts, was calculated. We assessed associations between GF and SCD phenotypic group, clinical and biological characteristics and history of SCD-related complications. GF was diagnosed in 51% of HbSS, 58% of HbSβ0 , 44% of HbSC, 38% of HbSβ+ patients and 32% of controls. GF in patients was positively associated with parents' lower education level, male sex, age 12-14 years, lower blood pressure, HbSS or HbSβ0 phenotypes, icterus, lower haemoglobin level, higher leucocyte count and microalbuminuria. No association was found between GF and clinical SCD-related complications. In sub-Saharan Africa, GF is still frequent in children with SCD, especially in males and during adolescence. GF is associated with haemolysis and microalbuminuria, but not with the history of SCD-related clinical complications.

Abstract
BACKGROUND Children with sickle cell disease (SCD) historically have been underweight and have poor overall growth. Recent studies have demonstrated a trend toward obesity in pediatric SCD populations. MATERIALS AND METHODS Through retrospective chart review of patients with SCD followed at our center, we collected patient's data, including body mass index (BMI), weight percentiles, sickle cell genotype, baseline hemoglobin, medical and psychiatric comorbidities, 25-hydroxy vitamin D level, treatment with hydroxyurea, and chronic transfusions. We identified hospitalizations to St. Christopher's Hospital for vaso-occlusive crisis (VOC) and duration of hospitalization and intravenous opioid use were recorded. Student t test, Mann-Whitney U test, and analysis of variance were used to examine associations between variables and frequency and duration of hospitalizations for VOC. RESULTS Among 328 patients with SCD, overweight and obese children constituted 19% of hospitalized and nonhospitalized patients. BMI status did not influence frequency (P=0.90) or duration of hospitalization (P=0.65) for VOC. Obesity was more associated with HbSC than HbSS (P=0.025) genotype. CONCLUSIONS Our study did not demonstrate an association between extremes of BMI of patients and hospitalization for VOC. Considering current trend toward obesity, further prospective and interventional research are required to define the effects of extremes of BMI on pain crises in SCD.

Abstract
Background. The aim of this study was to investigate and determine the risk factors associated with poor growth among SCA children. Methods. A cross-sectional study was conducted in Kinshasa, the capital's country. The nutritional status was assessed using the Z scores of the anthropometric indices. Results. We gathered data on the 256 patients, 138 females (53.9%), who entered the study. The mean age at presentation was 8.4 ± 4.9 years of age. Underweight, stunting, and wasting were found, respectively, in 47.7%, 10.5%, and 50.3% of SCA children. A history of hand-foot syndrome, more than 3 blood transfusions, being less than 12 months of age when receiving the first transfusion, more than two severe sickle crises per year, a medical history of severe infections, and the presence of hepatomegaly were associated with poor growth. When comparing sickle cell patients under 12 years of age (n = 159) to a group of 296 age-matched children with normal Hb-AA, a significantly higher proportion of subjects with stunting and underweight were found among SCA. Conclusion. Nutritional status encountered in Congolese sickle cell children has been described for the first time in this study. A high prevalence of poor growth in SCA children was found in our study.

Abstract
Objectives: The objectives of this study were to determine the anthropometric variables of children with sickle cell anaemia and comparing it with those with normal haemoglobin genotype. Methods: A cross sectional study of anthropometric measurements was conducted over a period of six months. Children with sickle cell anaemia in steady state aged between 6-20 years were recruited. Nutritional assessment was done using anthropometrical variables. Data were analyzed using the Statistical Package for Social Sciences program (SPSS), version 20. Results: The sickle cell patients comprised of 20 males and 20 females. There were an equal number of controls with an equal male to female ratio of 1:1. Forty eight percent (19) of the children with sickle cell anemia were underweight (< 5th %ile) and this is statistically significant. χ2=18.02 and p=0.000. When compared with subjects with normal haemoglobin genotype only five of them (13%) were underweight. χ2=10.286 and p=0.001. The controls weighed significantly more than the HbSS patients and also had significantly larger body surface compared to the HbSS population (P<0.05). Conclusion: BMI and other anthropometric variables among children with sickle cell anemia were low when compared with children with normal Haemoglobin genotype.

Abstract
Introduction La drépanocytose est une maladie génétique très polymorphe et la moitié des drépanocytaires homozygotes SS en Afrique meurt avant l’âge de 5 ans. Le but de cette étude est de déterminer les paramètres nutritionnels et hématologiques des jeunes drépanocytaires homozygotes (SS) congolais au cours de la phase stationnaire. Méthodes Nous avons fait à une étude descriptive comparative de deux groupes de patients dont l'un avec 41 sujets drépanocytaires (SS) d’âge moyen de 39,1mois et l'autre, groupe contrôle, avec 82 patients avec hémoglobine AA et d’âge moyen de 35,0 mois. Nous avons eu recours à un automate ABX Micros 60 pour l’évaluation hématologique. Pour l’évaluation nutritionnel nous avons étudiés le poids, la taille, l’âge ainsi que le sexe. Résultats Nous n'avons pas observé de différence significative entre les deux groupes par rapport à l’état nutritionnel (p > 0,05). L'hémogramme des homozygotes SS révèle une anémie chronique avec un taux moyen d'Hémoglobine à 8,33 ± 1,35g/dL. Cette anémie est normocytaire (VGM = 83,86 µm3), et régénérative (réticulocytes = 4,23±4,26%). Conclusion Nos résultats rencontrent ce qui est souvent décrit dans le syndrome drépanocytaire majeur sur les homozygotes SS avec haplotype bantu.

Abstract
BACKGROUND Body composition indices are widely used to evaluate growth and nutrition in children, particularly those with sickle cell anemia (SCA), who are known to have impaired growth, impaired skeletal maturation, and delayed puberty. The current study is aimed at determining the body composition of children with SCA. METHODS Consecutive selection of SCA children aged 6 to 18 years, who served as subjects and their age and gender matched children with HbAA (controls), selected using multi-stage systematic sampling. It was a cross-sectional descriptive study conducted at the pediatric hematology and oncology clinic. Bioelectric impedance analysis was used to determine the body composition parameters, including weight, body fat percentage (BFP), visceral fat percentage, body mass index (BMI), skeletal muscle percentage, and resting metabolic rate. Data were analyzed using SPSS 16.0 at P < 0.05. RESULTS One hundred and thirty-two subjects and controls respectively were studied. Subjects had lower body composition parameters compared with controls, with the older male subjects aged 10 to 18 years, having lower body composition indices (weight, height, BMI, and BFP) compared with controls. Visceral fat percentage was low in both subjects and controls. CONCLUSIONS Children with SCA, particularly the older males, have impaired body composition indices. There is a need to conduct further studies to determine the longitudinal aspects of growth as well as quantitative and qualitative assessment of nutritional intake in children with SCA, which will inform higher alimentation requirements for HbSS children as compared with HbAA individuals.

Abstract
Somatic growth is a key indicator of overall health and well-being with important prognostic implications in the management of chronic disease. Worldwide studies of growth in children and adults with SCD have predominantly shown delayed growth (especially in terms of body weight) that is gradual and progressive in nature. However, more recent studies have shown that a substantial number of patients with SCD have normal weight gain whereas some are even obese. Height in patients with SCD is not universally affected even among those with suboptimal weight gain, whereas some achieve the same or greater height than healthy controls. The relationship between somatic growth and lung function in SCD is not yet clearly defined. As a group, patients with SCD tend to have lower lung volumes compared with healthy controls. These findings are similar across the age spectrum and across ethnic/racial lines regardless of the differences in body weight. Several mechanisms and risk factors have been proposed to explain these findings. These include malnutrition, racial differences and socioeconomic status. In addition, there are structural changes of the thorax (specifically the anterio-posterior chest diameter and anterio-posterior to lateral chest ratio) specific to sickle cell disease, that potentially interfere with normal lung growth. Although, caloric and protein intake have been shown to improve both height and weight, the composition of an optimal diet remains unclear. The following article reviews the current knowledge and controversies regarding somatic growth and its relationship with lung function in sickle cell disease (SCD) as well as the role of specific deficiencies of certain micronutrients.

Abstract
BACKGROUND Reduced growth is common in children with sickle cell anemia, but few data exist on associations with long-term clinical course. Our objective was to determine the prevalence of malnutrition at enrollment into a hospital-based cohort and whether poor nutritional status predicted morbidity and mortality within an urban cohort of Tanzanian sickle cell anemia patients. DESIGN AND METHODS Anthropometry was conducted at enrollment into the sickle cell anemia cohort (n=1,618; ages 0.5-48 years) and in controls who attended screening (siblings, walk-ins and referrals) but who were found not to have sickle cell anemia (n=717; ages 0.5-64 years). Prospective surveillance recorded hospitalization at Muhimbili National Hospital and mortality between March 2004 and September 2009. RESULTS Sickle cell anemia was associated with stunting (OR=1.92, P<0.001, 36.2%) and wasting (OR=1.66, P=0.002, 18.4%). The greatest growth deficits were observed in adolescents and in boys. Independent of age and sex, lower hemoglobin concentration was associated with increased odds of malnutrition in sickle cell patients. Of the 1,041 sickle cell anemia patients with a body mass index z-score at enrollment, 92% were followed up until September 2009 (n=908) or death (n=50). Body mass index and weight-for-age z-score predicted hospitalization (hazard ratio [HZR]=0.90, P=0.04 and HZR=0.88, P=0.02) but height-for-age z-score did not (HZR=0.93, NS). The mortality rate of 2.5 per 100 person-years was not associated with any of the anthropometric measures. CONCLUSIONS In this non-birth-cohort of sickle cell anemia with significant associated undernutrition, wasting predicted an increased risk of hospital admission. Targeted nutritional interventions should prioritize treatment and prevention of wasting.

Abstract
BACKGROUND Poor growth and under-nutrition are common in children with sickle cell disease (SCD). This review summarises evidence of nutritional status in children with SCD in relation to anthropometric status, disease severity, body composition, energy metabolism, micronutrient deficiency and endocrine dysfunction. METHODS A literature search was conducted on the Medline/PUBMED, SCOPUS, SciELO and LILACS databases to July 2007 using the keywords sickle cell combined with nutrition, anthropometry, growth, height and weight, body mass index, and specific named micronutrients. RESULTS Forty-six studies (26 cross-sectional and 20 longitudinal) were included in the final anthropometric analysis. Fourteen of the longitudinal studies were conducted in North America, the Caribbean or Europe, representing 78.8% (2086/2645) of patients. Most studies were observational with wide variations in sample size and selection of reference growth data, which limited comparability. There was a paucity of studies from Africa and the Arabian Peninsula, highlighting a large knowledge gap for low-resource settings. There was a consistent pattern of growth failure among affected children from all geographic areas, with good evidence linking growth failure to endocrine dysfunction, metabolic derangement and specific nutrient deficiencies. CONCLUSIONS The monitoring of growth and nutritional status in children with SCD is an essential requirement for comprehensive care, facilitating early diagnosis of growth failure and nutritional intervention. Randomised controlled trials are necessary to assess the potential benefits of nutritional interventions in relation to growth, nutritional status and the pathophysiology of the disease.

Adverse effects of a clinically relevant dose of hydroxyurea used for the treatment of sickle cell disease on male fertility endpoints. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2009; 6:1124-44.

Abstract
Two experiments were conducted to determine: 1) whether the adult male transgenic sickle cell mouse (Tg58 x Tg98; TSCM), exhibits the patterns of reproductive endpoints (hypogonadism) characteristic of men with sickle cell disease (SCD) and 2) whether hydroxyurea (HU) exacerbates this condition. In Experiment 1, blood samples were collected from adult age-matched TSCM and ICR mice (ICRM) (N = 10/group) for plasma testosterone measurements. Subsequently, mice were sacrificed, testes excised and weighed and stored spermatozoa recovered for the determination of sperm density, progressive motility and percentage of spermatozoa with normal morphology. In experiment 2, adult male TSCM were orally treated with 25 mg HU/kg body weight/day for 28 or 56 days. Control mice received the vehicle for HU (saline) as described above. At the end of the treatment periods, blood samples were collected for quantification of circulating testosterone. Subsequently, mice were sacrificed, testes and epididymides were recovered and weighed and one testis per mouse was subjected to histopathology. Stored spermatozoa were recovered for the determination of indices of sperm quality mentioned in Experiment 1. Testis weight, stored sperm density, progressive motility, percentage of spermatozoa with normal morphology and plasma testosterone concentrations of TSCM were significantly lower by 40, 65, 40, 69 and 66%, respectively than those of ICRM. These data indicate that adult TSCM used in this study suffered from hypogonadism, characteristically observed among adult male SCD patients. In Experiment 2, HU treatment significantly decreased testis weight on day 28, (0.09 +/- 0.004 g) that was further decreased on day 56 (0.06 +/- 0.003 g; treatment x time interaction) compared with controls (day 28, 0.15 +/- 0.01 g; day 56, 2, 0.16 +/- 0.01 g). Concomitant with a 52% shrinkage (P<0.001) in area of testes in 56 days of HU treatment, testes from HU-treated TSCM exhibited significant atrophic degeneration in the seminiferous tubules compared with controls. Furthermore, treated TSCM had only Sertoli cells and cell debris remaining in most of the seminiferous tubules in comparison with controls. Leydig cell prominence and hyperplasia were more evident (P<0.05) in the steroidogenic compartments of testes of HU-treated TSCM compared with controls. However, plasma testosterone concentrations were reduced by HU treatment (P<0.05; treatment x time interaction) compared with controls on the two time periods studied. Epididymides from HU-treated TSCM sustained a 25% shrinkage (P<0.05), along with 69 (P<0.005) and 95% reduction (P<0.005), in stored sperm density and sperm progressive motility (treatment x time interaction P<0.05), respectively on day 56 of treatment compared with controls. These data demonstrate that TSCM used in this study exhibited SCD-induced hypogonadism, thus authenticating their use for studying the effect of HU on male reproductive endpoints observed in SCD patients. Secondarily, our data show that HU treatment exacerbated the already SCD-induced hypogonadism to gonadal failure.

Abstract
Previous studies of children with sickle cell disease (SCD) reported poor growth and delayed maturation. However, the prevalence, magnitude, and correlates of suboptimal growth remain poorly understood. A prospective longitudinal study was undertaken to determine the effects of disease severity and nutritional status on growth, an indicator of childhood well-being. Children, birth to 18 y of age, with SCD-SS were evaluated annually for 4 y. Growth, nutritional status, skeletal and sexual maturation, disease severity, dietary intake, and maternal education were assessed. In this sample of 148 children (78 females), growth in height, weight, or body mass index declined in 84% of subjects; 38% fell below the 5th percentile in one or more measures. Puberty was delayed 1 to 2 y, and median age at menarche was 13.2 y. Skeletal age was delayed by 0.7 +/- 1.4 y overall and by 1.3 +/- 1.5 y in children 10 to 15 y old. Height status declined over time and was positively associated with advancing puberty and hematological measures in girls, and nutritional status in girls and boys. Growth failure and maturational delay remain significant chronic problems in children with SCD-SS and are related to potentially modifiable factors such as nutritional status.

Abstract
As part of a larger study that examined pain experience, pain management, and pain outcomes among children with sickle cell disease, functional status (sleep, food intake, and activity levels) was examined during hospitalization for acute painful episodes. Children were asked to rate the amount of pain they experienced as well as the amount of time they slept, the amount of food they ate, and the amount of activity they had everyday. Children reported high levels of pain, which showed only a small decrease throughout hospitalization, and had disrupted sleep and wake patterns, decreased food intake, and decreased activity levels. Nurses need to routinely monitor functional status during acute painful episodes so that strategies to promote adequate sleep, food intake, and activity may be incorporated to minimize long-term negative outcomes in children with sickle cell disease.

Abstract
BACKGROUND Impaired growth, poor nutritional status, and delayed skeletal and sexual maturation are common in children with sickle cell disease (SCD), yet the nature of associated body-composition deficits has not been fully described. OBJECTIVE The objective was to assess growth, nutritional status, and body composition in 36 African American children with type SS SCD (20 females and 16 males) and 30 healthy control children (15 females and 15 males) of similar age (5-18 y) and ethnicity. DESIGN Height, weight, bone age, pubertal status, skinfold thickness, and arm circumference were assessed. Height and weight were converted to z scores by comparison with national reference data and skinfold-thickness measurements were converted to z scores by comparison with African American- specific reference data. Fat-free mass (FFM) and fat mass (FM) were estimated by using 4 methods. Prepubertal children, pubertal males, and pubertal females were analyzed separately. RESULTS Relative to the control subjects and to a national sample, children with SCD had significantly lower z scores for weight, height, arm circumference, and upper arm fat and muscle areas. Relative skeletal maturation was significantly delayed. After adjustment for age, children with SCD had significantly lower FM (prepubertal children and pubertal males only) and FFM (all 3 groups). CONCLUSIONS Children with SCD have impaired growth, delayed puberty, and poor nutritional status. Low z scores for upper arm fat area indicate deficits in fat (energy) stores, and low FFM coupled with low upper arm muscle area indicate muscle wasting and low protein stores. These body-composition abnormalities suggest that the nutritional needs of the African American children with SCD were not being met.

Abstract
BACKGROUND Poor growth and delayed maturation in children with sickle cell disease (SCD) may be due, in part, to mild zinc deficiency. OBJECTIVE The objective was to determine the effects of zinc supplementation on growth and body composition in children with SCD. DESIGN Forty-two prepubertal children (20 girls and 22 boys) aged 4-10 y with SCD-SS were randomly assigned to receive 10 mg elemental Zn/d in cherry syrup (zinc group) or cherry syrup alone (control group). The 2 groups were stratified by sex and initial height status. Dietary intakes were evaluated and anthropometric, high-precision knee-height, and plasma zinc measurements were made at baseline and at 3, 6, and 12 mo. Body composition was determined every 6 mo with dual-energy X-ray absorptiometry, and z scores for anthropometric variables were computed from national reference data. Longitudinal-mixed-effects analysis was used to test for differences between the groups over the 12-mo observation period. RESULTS Thirty-eight children completed the study. No significant differences were observed at baseline. After 12 mo, the zinc group had significantly greater mean (+/- SE) increases in height (0.66 +/- 0.29 cm/y), sitting height (0.97 +/- 0.40 cm/y), knee height (3.8 +/- 1.2 mm/y), and arm circumference z scores (0.27 +/- 0.12 cm/y). Height-for-age and weight-for-age z scores decreased significantly by 0.11 +/- 0.04 and 0.13 +/- 0.05, respectively, in the control group but did not change significantly in the zinc group. CONCLUSIONS Prepubertal children with SCD-SS may have zinc deficiency and may benefit from zinc supplementation to improve linear growth and weight gain.

Abstract
OBJECTIVES Although hydroxyurea is effective in treating adults with sickle-cell anemia (SCA), there is concern that it may adversely affect growth in children. We report the growth characteristics of patients in the Phase I-II pediatric hydroxyurea trial (HUG-KIDS) before and during treatment at the maximum tolerated dose for one year. STUDY DESIGN Children and adolescents with SCA (n = 68), aged 5 to 16 years at baseline, reached the maximum tolerated dose and had serial height, weight, and Tanner stage measurements. Data from the Cooperative Study of Sickle Cell Disease (CSSCD) were used for comparison. Mixed-effects models were used to compare serial measurements as a function of age and group. RESULTS In girls, there were no significant differences in height or weight among the pretreatment, on-treatment, and CSSCD groups. Compared with the CSSCD group, HUG-KIDS boys were heavier starting at age 9 years, and pretreatment HUG-KIDS boys were taller starting at age 7 years. The Tanner stage transitions took place at appropriate ages. CONCLUSIONS Hydroxyurea treatment had no adverse effect on height or weight gain or pubertal development in school-aged children with SCA.

Abstract
BACKGROUND The purpose of this study was to examine the relationships between growth in children with sickle cell anemia and the different beta-globin haplotypes, as well as components of the insulin-like growth factor (IGF)/insulin-like growth factor binding protein (IGFBP) axis. PATIENTS AND METHODS Growth parameters and plasma concentrations of growth hormone (GH), IGF-I, and IGFBP-3 were studied in 41 children with sickle cell anemia whose haplotypes were defined. RESULTS Plasma concentrations of IGF-I (total, free, and free/total fraction) and IGFBP-3 were significantly reduced in all patients with sickle cell anemia compared with the healthy children. Patients with the CAR/CAR haplotype had significantly lower mean growth velocity compared with those with Ben/Ben. When the GH/IGF axis elements were compared in relation with the different haplotypes, total IGF-I levels in CAR/CAR patients were significantly lower compared with levels in patients with Ben/Ben. A positive correlation was found between hematocrit and total IGF-I and between fetal hemoglobin percentages and the z-scores for total IGF-I and IGFBP-3. There was a positive correlation between age, weight, height, bone age, and the various elements of the GH/IGF-I axis when all groups were considered, although the correlation was lost when the auxologic data were expressed as standard deviation score for age. Growth velocity and the z-score for growth velocity were not correlated with any element of the axis. CONCLUSIONS The positive relationship between hematocrit and fetal hemoglobin percentages with total IGF-I, free/total IGF-I, and IGFBP-3 in patients with sickle cell anemia could show that the delayed growth of these patients may be linked to intrinsic factors of the disease, which also determine the low circulating concentrations of the various elements of the GH/IGF-I axis. It is reasonable to assume that decrease of total IGF-I concentrations in patients with CAR/CAR haplotype is secondary to the severity of the disease.

Abstract
The Igbo of Nigeria believe that everyone is ogbanje (reincarnates) but malevolent ogbanje differ from others in being revenge-driven, chronically ill and engaging in repeated cycles of birth, death and reincarnation. This study examined culturally defined symptoms of 100 children classified as malevolent ogbanje; and investigated their family history and child mortality experience. There was concordance between cultural descriptions of malevolent ogbanje and symptoms as manifested in sickle cell patients. Hemoglobin analysis showed that 70 of the 100 children had sickle cell disease (SCD); while 68 families had death-related names. The symptoms associated with Igbo cases of reincarnation, high child mortality rates, and the high prevalence of sickle cell disease among children classified as malevolent ogbanje all support the conclusion that the symptomatology and early mortality experience are related to sickle cell. Names with themes of death were prevalent in families of children described as malevolent ogbanje. The findings are discussed with reference to cultural resistance to SCD as an explanation for malevolent ogbanje and the implications for the health care of children with SCD in Nigeria.

Abstract
OBJECTIVE To investigate energy balance in children with sickle cell disease (SCD) as the possible cause of impaired growth and undernutrition. STUDY DESIGN Growth, resting (REE), total (TEE), and activity-related (AEE) energy expenditure and dietary intake were examined in 36 African American children with SCD (20 girls and 16 boys) and 30 control subjects (15 girls and 15 boys) of similar age (mean, 11.2 years) and ethnicity. TEE was measured by means of the doubly labeled water technique and REE by indirect calorimetry. AEE was calculated as TEE minus REE. Fat free mass (FFM) was calculated from skinfold prediction equations. RESULTS REE was significantly increased (131 kcal/d) in children with SCD (P =.001), after adjusting for sex and FFM. Children with SCD tended to have lower TEE (214 kcal/d) than control subjects, but there was no difference after adjusting for FFM and sex (P =.57). Children with SCD had significantly (P =.025) lower AEE (268 kcal/d) but only marginally (P =.08) lower AEE after adjusting for FFM and sex. CONCLUSIONS The elevated REE and lower AEE, in combination with poor growth status, indicate chronic energy deficiency in children with SCD. Further studies are needed to determine the best approaches to the treatment and prevention of undernutrition in children with SCD.

Abstract
Nutrition therapy is essential to the management of several chronic diseases affecting adolescents. Unfortunately, dietary impositions may evoke pathological eating-related cognitions. This pilot study examined eating- and weight-related cognitions of 55 adolescents attending a summer camp for youngsters with a heterogeneous variety of chronic diseases. Campers completed the Eating Cognitions Questionnaire and the Situational Obstacles to Dietary Adherence questionnaire. Campers whose medical regimens included special dietary recommendations (n = 24) were expected to have more cognitions associated with eating disorders than those without dietary restrictions (n = 31). Girls were significantly more concerned than boys about weight and restrictive dietary rules. Cognitions of youngsters with special dietary recommendations showed greater flexibility, less eating pathology and less weight concern than campers without recommended diets. Contrary to previous reports, dietary restrictions were associated with more appropriate eating cognitions, suggesting that adolescents with chronic illnesses requiring nutrition therapy may not necessarily bear greater risk of eating disorders.

Abstract
OBJECTIVE To investigate the role of haematological indices, socioeconomic status, and morbidity in prepubertal growth in homozygous sickle cell (SS) disease. METHOD Height, weight, and haematology were serially recorded in a cohort study of 315 children with SS disease from birth to 9 years at the sickle cell clinic of the University Hospital of the West Indies, Kingston, Jamaica. RESULTS Height increment between 3 and 9 years correlated positively with total haemoglobin at age 7 years in boys but not girls. Attained height and weight at age 7 years correlated positively with haemoglobin and fetal haemoglobin in boys but not girls. Only the correlation between haemoglobin and weight showed a significant gender difference. Partial correlation analysis suggested that the effect of haemoglobin was accounted for by the effect of fetal haemolglobin and further analysis indicated that height correlated with F reticulocyte count (a measure of fetal haemoglobin production) in both sexes but not with the ratio of F cells to F reticulocytes (a measure of F cell enrichment). Growth was not significantly related to mean red cell volume, proportional reticulocyte count, alpha thalassaemia, socioeconomic status, or morbidity. CONCLUSION A high concentration of fetal haemoglobin in boys with SS disease is associated with greater linear growth. It is postulated that in boys, low concentrations of fetal haemoglobin increase haemolysis and hence metabolic requirements for erythropoiesis, putting them at greater risk of poor growth. Differences in the relationship of haematology and growth between boys and girls with SS disease dictate that future analyses of growth take gender into account.

Abstract
OBJECTIVES To determine the effect of age on testicular function and fertility profile of adult males with homozygous sickle cell disease. DESIGN A comparative cross-sectional study. SETTING A university teaching hospital in Nigeria. PARTICIPANTS Twenty-two adult males with homozygous sickle cell disease and 20 healthy adult males with normal hemoglobin genotype. MAIN OUTCOME MEASURES Seminal indexes, serum concentration of reproductive hormones, body mass index (BMI), testicular volume index, and span-height difference of patients with homozygous sickle cell disease and normal subjects were compared. Also significant differences were sought between two age groups among patients and control subjects: those < or = 25 years old and those > 25 years of age. RESULTS The mean BMI, testicular volume index, serum T concentration, and indexes of semen quality of the patients with homozygous sickle cell disease were significantly lower than the values for the control subjects. In contrast, there was no significant difference in the mean concentration of FSH, LH, PRL, and mean span-height difference between both groups. Also, although no significant age-related effect on serum T concentration, testicular volume index, and sperm density was found in the subjects 18 to 40 years of age with normal hemoglobin genotype, patients > 25 years old with homozygous sickle cell disease had significantly higher mean serum T concentration and mean testicular volume index than those < or = 25 years old; their sperm density was also substantially higher. CONCLUSION Fertility is impaired in adult males with homozygous sickle cell disease probably as a result of abnormal hypothalamic or pituitary function. There is a significant amelioration of the hypogonadism, abnormal sexual function, and poor semen profile with increasing age.
