![]() Citation10 At present the focus is on the first 1 000 days, which is the crucial period for childhood development, Citation11 and therefore the appropriate window of opportunity for nutritional interventions for improved growth and development of children. Citation10 If nutrition intervention is not undertaken during the first 1 000 days, a child can be at risk of impaired development and increased risk of mortality. Citation9 However, intervention strategies should target the first 1 000 days of life (from conception to age two years), Citation9, Citation10 during which a child has an increased metabolic demand, increased nutrient needs, major tissue deposition, and rapid growth and development. Prevention of stunting can bring multiple benefits that include cognitive development, school achievement and better wages earned in adulthood. Citation5, Citation8 In addition, Casale and Desmond indicated that early intervention (before two years of age) is the best way to improve a child’s cognitive development. Citation5–7 Although cognitive gains are not assured as children grow older, there is a possibility for a child to catch up in height-for-age after the age of 24 months. Citation4 Stunting and underweight in young children are associated with poor cognitive development, which leads to poor school performance later in life. Poor nutrition leads to growth retardation, which both lead to serious public health implications and contribute to early-age morbidity and mortality. Citation3 This increase in the prevalence of stunting is a concern. In 2016, 27% of children under five years were stunted, Citation2 compared with 21.6% in 2012. In South Africa, however, an increase in the prevalence of stunting has been reported. Although the prevalence of stunting in the African region declined from 37.9% to 29.1%, it is the only region where the number of stunted children has increased over this time period, from 49.7 million in 2000 to 57.5 million in 2019, Citation1 due to population growth. Citation1 From 2000 to 2019 the global prevalence of stunting showed a steady decline, from 32.4% to 21.3%. Ever since then, it has evolved enormously together with the evolution of computers that have improved its calculation and data processing capacity.Globally in 2019, 144 million children aged under 5 years were stunted and 47 million were wasted, of whom 14.3 million were severely wasted. This is the latest stable version of a program that was first released back in the 1960s. The latter register all the instructions that can be carried out by means of SPSS commands. ![]() In the first place, data files with SAV extension, but it also operates with SPO output files containing all the information due to the manipulation of data (which can be exported in HTML or XLS format) and SPS syntax files. ![]() Preparation of data for fast and simple analyses.Wide range of statistical procedures for the precise analysis of information.These are the main features and functions of this software: Advanced data reduction, classification, and non-parametric test models.It comes along with a modular system similar to certain development languages, that expand the capacities fo the base system. It incorporate a system to install modules to expand some of the specific features of this software. You have a good amount of regression and advanced statistics procedures, which are perfect to create generalized linear models (GLM), generalized linear mixed models (GLMM), hierarchical linear models (HLM) and generalized estimation equations (GEE). It comes along with the functions necessary to carry out an in-depth analysis of linear models and obtain effective conclusions. Well, whether you're working with Big Data or in any other statistical data analyses, IBM SPSS Statistics can be the appropriate option as it's a piece of software recommended for statistics professional and students, equipped with powerful calculation tools. It can be used to isolate and identify patterns and trends in investigations applied to all sorts of fields. At this point of the story, you've probably already heard about Big Data and all the information that it can offer, processing huge amounts of data stemming from our activity on our electronic devices.
