Growth reference for Saudi preschool children: LMS parameters and percentiles

Abstract

BACKGROUND

Previous growth charts for Saudi children have not included detailed tables and parameters needed for research and incorporation in electronic records.

OBJECTIVES

The objective of this report is to publish the L, M, and S parameters and percentiles as well as the corresponding growth charts for Saudi preschool children.

DESIGN

Community-based survey and measurement of growth parameters in a sample selected by a multistage probability procedure.

SETTING

A stratified listing of the Saudi population.

SUBJECTS AND METHODS

Raw data from the previous nationally-representative sample were reanalyzed using the Lambda-Mu-Sigma (LMS) methodology to calculate the L, M, and S parameters of percentiles (from 3rd to 97th) for weight, length/height, head circumference, and body mass index-for-age, and weight-for-length/height for boys and girls from birth to 60 months.

MAIN OUTCOME MEASURES

Length or height and weight of Saudi preschool children.

RESULTS

There were 15 601 Saudi children younger than 60 months of age, 7896 (50.6 %) were boys. The LMS parameters for weight for age from birth to 60 months (5 years) are reported for the 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th, and 97th percentiles as well as the corresponding graphs. Similarly, the LMS parameters for length/height-for-age, head circumference-for-age, weight-for-length/height and body mass index-for-age (BMI) are shown with the corresponding graphs for boys and girls.

CONCLUSION

Using the data in this report, clinicians and researchers can assess the growth of Saudi preschool children.

LIMITATIONS

The report does not reflect interregional variations in growth.

The use of growth charts is one of the ways to assess nutrition and growth in children and adolescents.¹ Although the CDC 2000 reference growth charts for children in the United States are commonly used, the recently developed World Health Organization (WHO) Child Growth Standards and Reference have been developed and recommended as international growth charts.^2,3 However, many countries continue to use their own local charts.^4,5 In Saudi Arabia, following a few attempts to develop national growth charts,^6–8 nationally representative growth charts have been recommended for use in hospitals and clinics in Saudi Arabia.⁹ The current trend of using electronic medical records in Saudi Arabia requires calculation of additional variables, not available in previous analyses. These include the L, M, and S parameters percentiles and tables, which are useful to calculate other parameters including z-scores. We report the percentile tables for the L, M, and S parameters and the corresponding growth charts for preschool Saudi children. A similar analysis for older children from 5 to 18 years will be reported later.

SUBJECTS AND METHODS

The methodology of sampling, data collection and analysis have been reported.⁹ Briefly, the study sample was selected by multistage probability sampling procedure from a stratified listing based on the population census. Accordingly, the sample was representative of all the socioeconomic strata of each of the 13 regions of Saudi Arabia. Data collection was made by house-to-house visits where a survey questionnaire, clinical examination and body measurements were completed by primary care physicians and nurses. Data were analyzed after “cleaning” using new statistical methods.^10–12 The length of children younger than 3 years of age was measured in a supine position and the height was taken for children older than 3 years of age. Therefore, The terminology length/height is used to cover the age range from birth to 60 months. The weight is expressed in kilograms (kg) and length/height in centimeter (cm). As in previous analyses, the age was converted to Gregorian to facilitate comparison with growth charts of other populations.

Statistical methods

To calculate the percentiles of weight, height, body mass index and head circumference in boys and girls from birth to 60 months, the Lambda-Mu-Sigma (LMS) method was applied to synthesize the changing distribution of these anthropometric measurements during growth as a function of age. The LMS parameters are the median (M), the generalized coefficient of variation (S), and the power in the Box-Cox transformation (L). The LMS method corrects for skewness, represented by the Box-Cox transformation (lambda), to adjust the distribution of anthropometric data to a normal distribution by minimizing the effects of asymmetry.¹⁰ The LMS method is used to model the data, smooth the model parameters, and then estimate smoothed percentiles from the model parameters. The LMS method models the entire distribution taking into account degree of skewness (L), central tendency (M), and dispersion (S). The L M and S parameters are estimated and then smoothed. The parameters L, M and S were calculated according to the method of maximum penalized likelihood.¹⁰ Percentiles for all the anthropometric measures were estimated from those values applying the following formula:¹³

$$\text{P}=\text{M\hspace{0.17em}}[1+\text{LSZ}]\hspace{0.17em}1/\text{L},\hspace{0.17em}\text{L}\ne 0$$

Where the L, M, and S are the values from the appropriate table corresponding to the age in months of the child. Z is the z-score that corresponds to the percentile. Z-scores correspond exactly to percentiles, e.g., z-scores of −1.881, −1.645, −1.282, −0.674, 0, 0.674, 1.036, 1.282, 1.645, and 1.881 correspond to the 3rd, 5th, 10th, 25th, 50th, 75th, 85th, 90th, 95th, and 97th percentiles, respectively. Any desired percentile or z-score can be calculated from the smoothed L, M and S parameters.

For our data, we have calculated the 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th and the 97th percentiles for weight for age, height for age, head circumference-forage, weight for length/height, and added the 85th percentile for body mass index-for-age, commonly used to define overweight. Data processing was performed using the LMS Chart Maker Light 2.1 (Medical Research Council, London, UK). The goodness of fit of our all LMS models was assessed using the Q-test.

RESULTS

There were 15 601 Saudi children younger than 60 months (5 years) of age and 7896 (50.6%) were boys. The exact age at the time of growth measurement was calculated based on the date of birth in the birth certificate or family card subsequently converted to Gregorian dates. Only healthy children as determined by history and clinical examination performed by physicians were included.

Figure 1, 2, 3, 4, and 5 show the growth curves by for percentile (3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th, and 97th percentiles) for weight-for-age, length/height-for-age, head circumference-for-age, weight-for-length/height, and body mass index (BMI) for age for boys. Tables 1, 2, 3, 4, and 5 show the corresponding L M S parameters by percentile for weight-for-age, length/height-for-age, head circumference-for-age, weight-for-length/height, and BMI for age for boys. The same data for girls are shown in Figures 6, 7, 8, 9, and 10 with the corresponding tabular data in Tables 6, 7, 8, 9, and 10.

DISCUSSION

The development of a growth reference for children and adolescents is essential to monitor growth. Growth references have been developed for almost all developed countries,^2,4,5 and some developing countries.^14–17 For many years, many countries used the US national Center for Health Statistics (NCHS) growth charts adopted by the WHO, not because of accuracy, but because of the unavailability of alternatives as evidenced by the recent revised growth charts that are more representative of US children (the CDC 2000 growth charts for USA children).² Probably the most important milestone in the development of growth charts was the creation of the WHO Child Growth Standard as a result of a multicenter, multinational survey.³ Many physicians in Saudi Arabia use the US reference and some use the WHO Standards. This practice was acceptable when no nationally representative growth charts for Saudi children and adolescents were available. However, previous studies have shown clear differences in growth between Saudi and American children.^6–8 More recently, we have reported a nationally-representative growth reference for Saudi children that was recommended both by the Saudi Pediatric Association and the Saudi Council for Health Services, to be used instead of charts of other populations.⁹ As a result, we demonstrated that the use of CDC 2000 and the WHO standards to assess and follow the growth of Saudi children in clinics is not appropriate because of overdiagnosis of under-nutrition, stunting and short stature potentially resulting in unnecessary referral and investigation.^18,19 Therefore, there is little or no justification for the continued use of growth charts of other populations to assess the growth of Saudi children. Nevertheless, the WHO Child Growth Standards are probably the best reference to assess the nutritional status not in clinics and hospitals, but at the population level. A limitation of our study is that The report does not reflect interregional variations in growth.

Data on L, M, and S parameters, percentile tables, and corresponding growth charts for Saudi children have not been previously reported. This information is essential to health authorities and researchers in this era of conversion from traditional to electronic medical records. The availability of the L, M, and S parameters is essential to incorporate the Saudi growth charts in electronic medical records and enable researchers to calculate the z-scores of growth parameters. In addition, body mass index tables and graphs for Saudi preschool children have not been reported before. The BMI can now be used to screen Saudi children from birth to 60 months of age for overweight and obesity as well as thinness. This report provides clinicians and researchers with the L, M, and S parameters by percentiles that are needed for assessing the growth of Saudi preschool children.
