Evaluation of apparently healthy Egyptian infants and toddlers on the bayley-III scales according to age and sex.

BACKGROUND: Child development is shaped throughout the first years of life through the interaction of genetics and the environment. Bayley-III is valuably used to determine early developmental delay (DD). The aim of this study was to detect the differences in performance of a sample of apparently healthy Egyptian infants and toddlers on the Bayley-III scales in relation to their age and gender. METHODS: This was a cross-sectional study. Bayley scales were applied to 270 of the 300 recruited children following the inclusion criteria; to avoid potential risk factors affecting development. Assessment included cognitive, language and motor skills. Engaged children aged 18-42 months were divided into 4 age groups with six-month intervals. RESULTS: Approximately 78.4%, 76.2%, and 72% of the participants had average and above average scores in the cognitive, motor, and language domains, respectively. The language domain was characteristically impacted. The oldest age group (36-42 months) scored the highest means composite scores, while the 2nd group aged 24 - <30 months, scored the lowest means in the three evaluated domains. In general, girls had non-significantly higher composite scores than boys, with a small effect size (d = 0.2-0.4). In the language domain, girls aged 30 to < 36 months scored significantly higher composite scores than boys (p < 0.05), with a medium effect size (d = 0.73). CONCLUSION: The study indicates that the performance of apparently healthy Egyptian children on the Bayley III evaluation differs in relation to age and sex. The most vulnerable age group at potential risk of DD was children aged 24-30 months. Efforts must be directed to investigate the nutritional, physical, psychological and safety needs of this group. Attention must be paid to early childhood intervention programs that stimulate development, especially language development, and they must be tailored on the basis of age and gender. Gender-specific norms may be needed in the evaluation of language development.

Screening and determinant of suspected developmental delays among Egyptian preschool-aged children: a cross-sectional national community-based study.

BACKGROUND: Early childhood life is critical for optimal development and is the foundation of future well-being. Genetic, sociocultural, and environmental factors are important determinants of child development. AIM: The objectives were to screen for suspected developmental delays (DDs) among Egyptian preschool children, and to explore the determinants of these delays based on sociodemographic, epidemiological, maternal, and child perinatal risk factors. METHODS: A national Egyptian cross-sectional developmental screening of a representative sample of preschool children (21,316 children) aged 12 to 71 months. The Revised Denver Prescreening Developmental Questionnaire (R-PDQ) followed by the Denver Developmental Screening Test, 2nd edition (DDST) was used. RESULTS: Each screened child manifested at least one of six developmental categories. Either typical development, gross motor delay (GM), fine motor adaptive delay (FMA), Language delay (L), Personal-social delay (PS), or multiple DDs. The prevalence of preschool children with at least one DD was 6.4%, while 4.5% had multiple DDs. Developmental language delay was the most prevalent, affecting 4.2% of children. The least affected domain was GM (1.9% of children). Boys were more likely to have DD than girls. Children in urban communities were more likely to have at least one DD than those in rural areas (OR = 1.28, 95%CI: 1.14-1.42), and children of middle social class than of low or high social class (OR = 1.49, 95%CI: 1.30-1.70 & OR = 1.40, 95%CI: 1.23-1.59 respectively). The strong perinatal predictors for at least one DD were children with a history of postnatal convulsions (OR = 2.68, 95%CI: 1.97-3.64), low birth weight (OR = 2.06, 95%CI: 1.69-2.52), or history of postnatal cyanosis (OR = 1.77, 95%CI: 1.26-2.49) and mothers had any health problem during pregnancy (OR = 1.73, 95%CI: 1.44-2.07). Higher paternal and maternal education decreased the odds of having any DD by 43% (OR = 0.57, 95% CI: 0.47-0.68) and 31% (OR = 0.69, 95%CI: 0.58-0.82) respectively. CONCLUSION: This study demonstrates a considerable attempt to assess the types and the prevalence of DD among preschool children in Egypt. Perinatal factors are among the most common determinants of DD in preschool children and the majority could be preventable risk factors.

Prevalence and risk factors of disabilities among Egyptian preschool children: a community-based population study.

BACKGROUND: Child disability has significant implications on their well-being and healthcare systems. AIM: This survey aimed to assess the magnitude of seven types of disability among Egyptian children aged 1 < 6 years and their socio-demographic, epidemiological, and perinatal predictors. METHODS: A national population-based cross-sectional household survey targeting 21,316 children from eight governorates was conducted. The screening questionnaire was derived from the WHO ten-question survey tool validated for identifying seven disability categories. RESULTS: The percentage of children with at least one disability was 8.1% as follows: speech/communication (4.4%), Mobility/physical (2.5%), Seizures (2.2%), Comprehension (1.7%), Intellectual impairment (1.4%), Visual (0.3%) and Hearing (0.2%). Age was not found to affect the odds of disability except for visual disability (significantly increased with age (AOR = 1.4, 95% CI:1.1-1.7). Male sex also increased the odds of all disabilities except visual, hearing, and seizures. Convulsions after birth significantly increased the odds of disability as follows: hearing (AOR = 8.1, 95% CI: 2.2-30.5), intellectual impairment (AOR = 4.2, 95% CI: 2.5-6.9), and mobility/physical (AOR = 3.4, 95% CI: 2.3-5.0). Preterm delivery and being kept in an incubator for more than two days after birth increased the odds for visual disability (AOR = 3.7, 95% CI: 1.1-12.1 & AOR = 3.7, 95% CI: 1.7-7.9 respectively). Cyanosis increased the odds of seizures (AOR = 4.7, 95% CI: 2.2-10.3). Low birth weight also increased the odds for all disability domains except for visual and hearing. Maternal health problems during pregnancy increased the odds for all types of disability except hearing and seizures. Higher paternal education decreased the odds for all disabilities by at least 30% except for vision and hearing. CONCLUSION: The study found a high prevalence of disability among Egyptian children aged 1-6 years. It identified a number of modifiable risk factors for disability. The practice of early screening for disability is encouraged to provide early interventions when needed.

The Interaction of Social, Physical and Nutritive Factors in Triggering Early Developmental Language Delay in a Sample of Egyptian Children.

BACKGROUND: Language acquisition and child development during the early years of life depend on multiple interacting factors. AIM: To explore potential factors that can impact language development in 2 groups of Egyptian children, one with normal language development and the second with delayed development. Also, to explore to what extent can the involvement of impaired motor development potentiate the risk of developmental language delay. METHODS: This cross-sectional case-control study involved Egyptian children belonging to the middle socioeconomic class between 18 and 36 months of age. Children were classified according to their performance on language domain of Bayley Scales of Infant and Toddler Development (Bayley-III) into two groups, infants with the average or above score (control group) and those having below-average scores (cases). Motor development was assessed on the same scale. Factors affecting language development were tested, including socio-demographic, obstetric, and maternal medical factors in addition to Infant Feeding Practices. RESULTS: The independent factors lowering the language scores were early introduction of complementary food, low family income, history of delivery problems, pregnancy-related diseases of the mother, and maternal education. Impaired motor development appears as a further highly significant risk factor to the previously mentioned factors. CONCLUSION: In Egyptian children, delayed language development is severely affected by the interaction of medical, social and nutritional factors. Providing adequate maternal health care during pregnancy and childbirth, regular developmental monitoring at each child visit, and screening for such risk factors, can reduce size of the problem and promote child's social and psychological development.

Potential Risk Factors of Developmental Cognitive Delay in the First Two Years of Life.

BACKGROUND: The first two years of life constitute a critical period of rapid change. The events during this phase prepare the child for subsequent developmental competency. AIM: To determine the potential risk factors that affect an infant's cognitive development in the first two years of life in a sample of Egyptian infants. SUBJECTS AND METHODS: A cross-sectional comparative study included 655 male and female infants. Their age ranged from 3 - 24 months. Bayley Scales of Infant and Toddler Development (Bayley III) were used for cognitive assessment. Perinatal and nutritional data were recorded. Levels of serum Zinc, Copper, Iron, vitamin B12 and complete blood count (CBC) were assessed in a subsample of 193 infants. RESULTS: Infants having below the average cognitive composite score (CCS) represented 38.47% of the whole sample. The risk of having a low average (CCS) was determined by multiple factors. Poor maternal education and low family income were the most significant social risk factors (OR = 2.19, p = 0.0003; OR = 1.64, p = 0.002 respectively). Prematurity and complicated labor represented significant perinatal risks (OR = 1.22, p = 0.005; OR = 2.39, p =0.001respectively). Bottle feeding versus breastfeeding in the first six months of life was the most significant nutritional predictor of low average (CCS) (OR = 1.79, p = 0.001). Infants with low average (CCS) had significantly lower levels of serum zinc and vitamin B12 than those with average scores. CONCLUSION: Multiple factors appear to interact affecting the early cognitive development of Egyptian infants. Prematurity, complicated labour, poor maternal education, low family income and micronutrient deficiency are the main risk factors. Studying these factors is of great value in directing governmental intervention efforts.

Determinants of Exclusive Breastfeeding in a Sample of Egyptian Infants.

BACKGROUND: Breastfeeding is an optimum, healthy, and economical mode of feeding an infant. However, many preventable obstacles hinder exclusive breastfeeding in the first six months of life. AIM: We aimed to assess the social-, maternal- and infant-related factors disturbing exclusive breastfeeding in the first six months of life. METHODS: It is a retrospective study included 827 dyads of mothers and infants older than 6 months (411 exclusively breastfed, 311 artificially-fed and 105 mixed feds). Mothers were interviewed to obtain sociodemographic information, maternal medical history and perinatal history and a detailed history of infant feeding. RSULTS: Many factors were found to support the decision for artificial feeding rather than exclusive breastfeeding, including maternal age < 25 years (OR = 2.252), child birth order > 3rd (OR = 2.436), being a primi-para (OR = 1.878), single marital status (OR = 2.762), preterm infant (OR = 3.287) and complicated labor (OR = 1.841). Factors in favor of mixed feeding included cesarean section (OR = 2.004) and admission to the Neonatal Intensive Care Unit (OR = 1.925). CONCLUSIONS: Although it isn't a community-based study and its results can't be generalised, plans to improve health and development of children are preferable to include the following: health education and awareness programs about the importance of exclusive breastfeeding should be directed for young and first-time mothers. Improved antenatal care to reduce perinatal and neonatal problems; and training, monitoring, and supervising community health care workers to recognise labour complications and provide support and knowledge to lactating mothers.

Academic Achievement and Psychosocial Profile of Egyptian Primary School Children in South Sinai.

BACKGROUND: Population of South Sinai has suffered from negligence for many years. Solving educational problems of this population is the main concern nowadays. AIM: To assess academic achievement in primary school children in South Sinai in relation to intelligence and psychosocial profile. SUBJECTS AND METHODS: A descriptive cross-sectional survey was conducted on 407 Bedouin and urban students randomly selected from twelve public primary schools in six cities in South Sinai. Intelligence was assessed using Goodenough-Harris test. The midyear Arabic language and Arithmetic scores were used to assess academic achievement. The teachers completed a Pediatric-Symptom Checklist for evaluation of children behaviour. RESULTS: A statistically significant difference in academic achievement (P < 0.001), total psychosocial scores, (P < 0.05), and externalization (P < 0.05) was found between urban and Bedouin students with significant gender differences (P < 0.05). Highly significant positive correlations were observed between IQ percentile and mid-year Arabic language scores and Arithmetic scores (P < 0.001), and significant negative correlations with the total score of PSCL and its subscale scores (externalising, inattention, and internalising behaviour) (P < 0.001) among the students. CONCLUSION: Comorbid academic and psychosocial dysfunction in primary school children were observed in South Sinai. A national strategy to minimise the educational gap between Bedouin and urban areas should be implemented.

Association of Serum 25-Hydroxyvitamin D with Life Style and Dietary Factors in Egyptian Prepubescent Children.

BACKGROUND: There had been a growing evidence of high prevalence of vitamin D deficiency especially among children which may increase the risk of many chronic diseases in adulthood. AIM: Assessment of different lifestyles and dietary behaviour influencing the level of serum 25-OHD in a group of Egyptian prepubescent children. SUBJECTS AND METHODS: Two hundred boys and girls aged from 9 to 11 years were recruited from two primary public schools situated in Giza governorate in Egypt. A questionnaire was developed to obtain relevant information related to age, dietary habits, and physical activity. Thorough clinical examination and measurement of weight and height were performed. Body mass index was calculated. Serum samples were assayed for 25-hydroxy vitamin D (25-OHD). RESULTS: Low serum 25-OHD (< 20 ng/ml) was found in 11.5% of the whole sample. Mean serum 25-OHD was significantly lower in obese subjects and in those with low physical activity (p < 0.05). Multiple stepwise linear regression analysis showed that BMI and physical activity were the main predictors of serum 25-OHD (P < 0.05). CONCLUSIONS: Lifestyle factors in terms of physical activity and BMI may contribute significantly to the optimal vitamin D status of apparently healthy children.
