Relationship between periodontal status and intellectual function among community‐dwelling elderly persons

The aim of this study was to indicate the relationship between periodontal status and intellectual function in the elderly. Periodontal status has been shown to be related to demographic, socioeconomic, and psychological status. Intellectual function is a significant indicator of health status. Nevertheless, the relationship between periodontal status and intellectual function has not been elucidated in detail among the elderly. A total of 152 community-dwelling elderly persons, aged 70-74 years, were enrolled in the study. Periodontal status was evaluated using the WHO Community Periodontal Index of Treatment Needs (CPITN). Intellectual function was assessed by four neuropsychological tests: Raven's Coloured Progressive Matrices (RCPM) test, the Verbal Paired Associates 1 (VerPA) task and the Visual Paired Associates 1 (VirPA) task, extracted from the Wechsler Memory Scale Revised Edition, and the Block Design subtest, extracted from the Wechsler Adult Intelligence Scales, Third Edition. Correlations between CPITN and each test were examined using Spearman rank correlation coefficients. The ordinal regression model was constructed with CPITN as the dependent variable and neuropsychological test as the principal independent variable to adjust for demographic factors, general health, lifestyle and oral health behaviour. Significant correlations were found between the RCPM test, the VerPA task, the Visual Paired Associates 1 and CPITN. In the ordinal regression model, CPITN was significantly related to measures of RCPM after adjusting for demographic factors, general health status, lifestyle and oral health behaviour. Intellectual function is considered a significant indicator of periodontal status among community-dwelling elderly persons.

Development of non‐verbal intellectual capacity in school‐age children with cerebral palsy

Children with cerebral palsy (CP) are at greater risk for a limited intellectual development than typically developing children. Little information is available which children with CP are most at risk. This study aimed to describe the development of non-verbal intellectual capacity of school-age children with CP and to examine the association between the development of non-verbal intellectual capacity and the severity of CP. A longitudinal analysis in a cohort study was performed with a clinic-based sample of children with CP. Forty-two children were assessed at 5, 6 and 7 years of age, and 49 children were assessed at 7, 8 and 9 years of age. Non-verbal intellectual capacity was assessed by Raven's Coloured Progressive Matrices (RCPM). Severity of CP was classified by the Gross Motor Function Classification System, type of motor impairment and limb distribution. manova for repeated measurements was used to analyse time effects and time × group effects on both RCPM raw scores and RCPM intelligence quotient scores. The development of non-verbal intellectual capacity was characterised by a statistically significant increase in RCPM raw scores but no significant change in RCPM intelligence quotient scores. The development of RCPM raw scores was significantly associated with the severity of CP. Children with higher levels of gross motor functioning and children with spastic CP showed greater increase in raw scores than children with lower levels of gross motor functioning and children with dyskinetic CP. Children with CP aged between 5 and 9 years show different developmental trajectories for non-verbal intellectual capacity, which are associated with the severity of CP. The development of non-verbal intellectual capacity in children with less severe CP seems to resemble that of typically developing children, while children with more severe CP show a limited intellectual development compared to typically developing children.

The impact of emotional intelligence and intelligence quotient (IQ) on child anxiety and behavior in the dental setting

Objective. The aim of this study was to evaluate the impact of IQ and EQ on child's anxiety and behavior in the dental setting. Materials and methods. One hundred and seven children (age range 7–12 years) were selected. BarOn Emotional Quotient Inventory: Youth Version (Baron EQ-I: YV) and the Raven's Colored Progressive Matrices (RCPM) tests were administered on the first examination session. Children's anxiety and behavior were evaluated using the modified child dental anxiety scale (MCDAS) and the sound, eye and motor (SEM) scales, respectively, during the second session. Results. The mean (SD) age of subjects was 8.48 (1.41) years old. The result revealed a significant negative correlation between children's behavior and total EQ score (p < 0.01) but there was no relationship found between children's behavior and IQ score. A significant positive correlation was found between anxiety scores on MCDAS and SEM (p < 0.01), but no relationship was found between EQ and MCDAS scores. Both anxiety (p < 0.01) and EQ score (p < 0.01) were effective variables in predicting the child's SEM score. Conclusion. The major finding of this research suggested that a high EQ may be more effective than a low EQ in moderating the level of cooperation during dental treatment of children. IQ scores, on the other hand, were related to the child's EQ score (r = 0.20) and age (r = – 0.29).

Associations between self-assessed masticatory ability and higher brain function among the elderly

Among the elderly, the quality of higher brain function is a contributing factor in performing activities of daily living. The aim of the study is to elucidate, epidemiologically, associations between mastication and higher brain function. A total of 208 community-dwelling elderly persons, aged 70-74 years, were enrolled. Self-assessed masticatory ability (masticatory ability) was classified into one of three categories: ability to chew all kinds of food, ability to chew only slightly hard food, or ability to chew only soft or pureed food. Brain function was assessed by four neuropsychological tests: Raven's Colored Progressive Matrices (RCPM) test, the Verbal Paired Associates 1 (VerPA) task and the Visual Paired Associates 1 task (from the Wechsler Memory Scale Revised Edition), and the Block Design subtest (from the Wechsler Adult Intelligence Scales-Third Edition). Correlations between masticatory ability and each test were examined using Spearman rank correlation coefficients. Multinominal logistic regression models were conducted with the neuropsychological tests as the dependent variables and masticatory ability as the principal independent variable to adjust for age, gender, educational background, social activity, drinking/smoking habits, chronic medical conditions and dental status. Significant correlations were found between the RCPM test, the VerPA task, the Block Design test and masticatory ability. In multinominal logistic regression models, poor masticatory ability was significantly and independently related to the categories under the mean-s.d. points compared with those of the mean ± s.d. ranges for RCPM test and the VerPA task. Significant associations may exist between mastication and higher brain function among the elderly.

Long-term effects of iron and zinc supplementation during infancy on cognitive function at 9 y of age in northeast Thai children: a follow-up study

Iron and zinc are important micronutrients for child growth and development. One would expect that iron and zinc supplementation in infancy would affect long-term cognitive development and school achievement, but this has not been evaluated. We investigated the effect of iron or zinc supplementation or both during infancy on cognitive performance 8 y later. A follow-up study was performed in 560 children aged 9 y or 92% of those who had participated in a randomized controlled trial involving 4 groups who received daily iron, zinc, iron plus zinc, or a placebo at 4-6 mo of age for 6 mo. Cognitive performance was assessed by using the Wechsler Intelligence Scale for Children-Third Edition (Thai version), the Raven's Colored Progressive Matrices (CPM), and school performance tests. General linear mixed models were used to assess long-term effects. No significant differences in any of the outcomes at 9 y of age were observed at follow-up between the 4 groups. Mean intelligence quotients ranged across groups from 92.9 to 93.7 for full scale, 93.9-95.4 for verbal, and 93.1-94.0 for performance. The Raven's CPM score ranged from 21.4 to 22.4. Supplementation with iron or zinc or both during infancy does not lead to long-term cognitive improvement in 9-y-old children. This trial was registered at clinicaltrials.gov as NCT00824304.

Clinical profiles of late‐onset semantic dementia, compared with early‐onset semantic dementia and late‐onset Alzheimer's disease

Semantic dementia (SD) has been recognized as a representative of dementia with presenile onset; however, recent epidemiological studies have shown that SD also occurs in the elderly. There have been few studies about the differences of clinical profiles between early-onset SD (EO-SD) and late-onset SD (LO-SD). Age-associated changes in the brain might cause some additional cognitive and behavioural profiles of LO-SD in contrast to the typical EO-SD cases. The aim of the present study was to clarify the characteristics of neuropsychological, and behavioural and psychological symptoms of dementia (BPSD) profiles of LO-SD patients observed in screening tests in comparison with EO-SD patients and late-onset Alzheimer's disease (LO-AD) patients as controls. Study participants were LO-SD (n = 10), EO-SD (n = 15) and LO-AD (n = 47). We examined the Mini-Mental State Examination (MMSE), the Raven's Coloured Progressive Matrices (RCPM), the Short-Memory Questionnaire (SMQ), the Neuropsychiatric Inventory (NPI) and the Stereotypy Rating Inventory (SRI). Both SD groups scored significantly lower than the LO-AD patients in 'naming' of the MMSE. In the 'construction' score of the MMSE and the RCPM score, however, the LO-SD patients as well as the LO-AD patients were significantly lower than the EO-SD patients. In the SMQ score, 'euphoria' and 'disinhibition' scores of the NPI, the SRI total and subscale scores, both SD groups were significantly higher, whereas in the 'delusion' score of the NPI, both SD groups were significantly lower than the LO-AD patients. Visuospatial and constructive skills of LO-SD patients might be mildly deteriorated compared with EO-SD patients, whereas other cognitive and behavioural profiles of LO-SD are similar to EO-SD. Age-associated changes in the brain should be considered when we diagnose SD in elderly patients.

P01-353 - A comparative efficacy of holistic multidimensional treatment model (HMTM) and applied behavioral analysis (ABA) in the treatment of children with autism spectrum disorder (ASD)

IntroductionSeveral approaches have been presented for treatment of children with ASD. The aim of the present study was to compare the efficacy of Holistic Multidimensional Treatment Model (HMTM) with Applied Behavioral Analysis (ABA) in the improvement of clinical symptoms of children with ASD.MethodThe present study was an experimental pre and post test research. The statistical population included the 3 to 8 year old children with ASD who were referred to the child psychiatry clinics in two academic Hospitals- Mashhad,Iran. The sample included 20 children who were selected with convenience sampling and randomly divided to 2 groups of ABA (8 boys and 2 girls) and HMTM (7 boys and 3 girls).The diagnosis was made by a child psychiatrist based on DSM-IV-TR criteria and using Autism Diagnostic Interview-Revised (ADIR) and Autism Diagnostic Observation Schedule (ADOS).Then the children were referred to Noore Hedayat center for the treatment. Childhood Autism Rating Scale (CARS), Bender Gestalt Test, Draw-A-Man Test Good enough, Raven's Colored Progressive Matrices Test for children, Vineland Social Maturity Scale (VSMS) and performance charts of children based on their videotaped behaviors. Data analysis was done using ANCOVA test.ResultsFindings showed that in spite of more efficacy of HMTM compared to ABA, the differences of standard tests except Bender Gestalt Test and performance charts did not reach to the significant level(p &gt; 0.05).ConclusionIn conclusion, HMTM at least had the equal efficacy to ABA in the treatment of children with Autism Spectrum Disorder. Further researches are needed to compare the efficacy of these 2 methods.

Drawing from memory in focal epilepsy: A cognitive and neural perspective

This study provides evidence of non-verbal cognitive functioning in temporal (TLE) and frontal lobe epilepsy (FLE) patients by exploring the mechanisms and neural correlates of drawing abilities. Sixty-six patients with left (n=32) or right TLE (n=34), 30 patients with left (n=18) or right FLE (n=12), and 30 healthy subjects were compared. The Drawing from Memory (DfM) test required participants to design 16 living or non-living items; the total score was the sum of all scores blindly provided by three judges who had to identify the drawings. The verbal and visual Pyramid and Palm Trees Test (PPTT), Raven Colored Progressive Matrices (Raven CPM), Cube Analysis, Token Test, Word Fluency, Card Classification, and Rey Complex Figure Test Copy trial (Rey CFC) assessed different verbal and non-verbal functions. Non-parametric statistics indicated that, with respect to controls, both TLE groups and the left FLE patients had significantly lower DfM scores. In the TLE group, hierarchical regression analyses revealed that the DfM score was predicted by the Raven CPM and PPTT scores, while, in the FLE group, it was predicted by the Rey CFC. Thus, drawing abilities may be impaired by TLE or FLE owing to different mechanisms that involve semantic or executive abilities. Implying cooperation between temporal and frontal areas that support these functions, DfM may be a sensitive index of integrity of cortical areas or neural pathways damaged by focal epilepsy.

Genetic and Environmental Influences on Chinese Language and Reading Abilities

This study investigated the etiology of individual differences in Chinese language and reading skills in 312 typically developing Chinese twin pairs aged from 3 to 11 years (228 pairs of monozygotic twins and 84 pairs of dizygotic twins; 166 male pairs and 146 female pairs). Children were individually given tasks of Chinese word reading, receptive vocabulary, phonological memory, tone awareness, syllable and rhyme awareness, rapid automatized naming, morphological awareness and orthographic skills, and Raven's Coloured Progressive Matrices. All analyses controlled for the effects of age. There were moderate to substantial genetic influences on word reading, tone awareness, phonological memory, morphological awareness and rapid automatized naming (estimates ranged from .42 to .73), while shared environment exerted moderate to strong effects on receptive vocabulary, syllable and rhyme awareness and orthographic skills (estimates ranged from .35 to .63). Results were largely unchanged when scores were adjusted for nonverbal reasoning as well as age. Findings of this study are mostly similar to those found for English, a language with very different characteristics, and suggest the universality of genetic and environmental influences across languages.

Consciência sintática: prováveis correlações com a coerência central e a inteligência não-verbal no autismo

To evaluate syntactic awareness, central coherence, non-verbal intelligence, social and communication development, interests and behavior of children with autistic spectrum disorders and to examine their probable correlations. Participants were ten subjects diagnosed with autistic spectrum disorder, eight male and two female, with ages between 4 years e 9 months and 13 years and 4 months (mean age 9 years), who used oral language for communication. The following tests were used: Syntactic Awareness Test - Adapted (Prova de Consciência Sintática - Adaptada), Computerized jigsaw puzzles with picture and background and only with background; and Raven's Coloured Progressive Matrices - Special Scale. Subjects' parents answered the protocol Autism Diagnostic Interview - Revised (ADI-R). The children with autism presented syntactic awareness performance similar to that of 6-year-old children with typical development. Sixty percent of the subjects showed non-verbal intelligence at a superior or average level. There were no correlations between the performances in syntactic awareness and the other tested variables. There was no relationship between the performance in syntactic awareness and the results related to central coherence, non-verbal intelligence and social interaction deficits, difficulties in communication and restrict patterns interests of subjects with autism. The results suggest that these children seem to follow the development pattern of typically developing 6-year-old children in syntactic awareness abilities, only delayed.

Relation between dental fluorosis and intelligence quotient in school children of Bagalkot district

This study was conducted on 160 children, in the Bagalkot district of Karnataka state between August and October 2010, with the aim of finding out if there is a relation between dental fluorosis status and Intelligence Quotient (IQ). Children were categorized as, those suffering from dental fluorosis and those not suffering from dental fluorosis and for all children in both categories, Intelligence testing was done using the Raven's Coloured Progressive Matrices. The following observations were made from the data gathered: The mean IQ score of children without dental fluorosis was significantly higher than those children who had dental fluorosis. The mean IQ scores did not vary with the severity of dental fluorosis as classified by Dean's fluorosis index. Also it was noticed that the percentage of children with dental fluorosis was more in Extremely Low and Low IQ categories whereas the percentage of children without dental fluorosis was more in Average and High Average IQ categories. Previous studies had indicated toward decreased Intelligence in children exposed to high levels of fluoride and our study also confirmed such an effect.

The role of working memory and updating in Coloured Raven Matrices performance in typically developing children

A large body of evidence indicates that working memory correlates with performance on fluid intelligence tasks such as Raven's tests. However, light still needs to be shed on which particular aspects of working memory might be most critically related to fluid intelligence, and whether working memory updating—which appears crucial to intellectual functioning—has a prominent role. To address these issues more closely, our study presented participants (aged 5–11 years) with the Raven's Coloured Progressive Matrices, an updating task, and a battery of working memory tasks. Our findings confirm that working memory indeed plays an important part in explaining fluid intelligence, in particular that updating information in working memory is critical to fluid intelligence in the context of development.

Development of daily activities in school-age children with cerebral palsy

The purpose of this study was to describe the course of capabilities in self-care, mobility, and social function in school-age children with cerebral palsy (CP) and to investigate associations with CP-, child-, and family-characteristics. A clinic-based sample of children with CP ( n = 116; 76 males, 40 females; mean age 6 y 3 mo, SD 12 mo) was followed longitudinally in three yearly measurements. Children's capabilities were assessed with the Pediatric Evaluation of Disability Inventory Functional Skills Scale (PEDI-FSS). Averaged for the total group, significant increases over time were shown in PEDI-FSS scores in all three domains. For self-care, the course was best predicted by a model including level of gross motor function (measured by the Gross Motor Function Classification System) and intellectual capacity (measured by Raven's Coloured Progressive Matrices). For mobility, the course was best predicted by a model containing only level of gross motor function. For social function, the course was best predicted by a model comprising level of bimanual function (measured by the Manual Ability Classification System) and paternal educational level. Generally, the increase in capabilities was greater if level of functioning was higher, except for level of paternal education. The findings indicate that there are different sets of determinants for the course of different domains of daily activities. Such different sets of determinants may help to set realistic expectations and to create appropriate treatment plans for different domains of daily activities in school-age children with CP.

Item and error analysis on Raven's Coloured Progressive Matrices in Williams Syndrome

Raven's Coloured Progressive Matrices (RCPM) is a standardised test that is commonly used to obtain a non-verbal reasoning score for children. As the RCPM involves the matching of a target to a pattern it is also considered to be a visuo-spatial perception task. RCPM is therefore frequently used in studies in Williams Syndrome (WS), in order to match WS participants to a control group or as a single measure to predict performance on a test-condition in developmental trajectory analyses. However, little is known about the performance of participants with WS on the RCPM. The current study compared the type of errors and the difficulty of each item for 53 participants with WS to 53 typically developing children who were individually matched on the total raw score for RCPM. Results showed that the participants with WS made the same proportion of error types and that the proportion of error types changed similarly to those of typically developing controls over development. Furthermore, the differential item difficulty between the two groups was highly similar. It is therefore argued that, although participants with WS are delayed on RCPM, their performance is not atypical which suggests that RCPM performance is supported by typical mechanisms. The RCPM is therefore a useful tool to match WS to control groups or to construct developmental trajectories.

Nutritional and socioeconomic status in cognitive development of Santal children of Purulia district, India

Background: Cognitive development of children depends on nutritional and socioeconomic factors.Objectives: The objectives of the present study were to assess the cognitive development and to investigate the relationship of nutritional and socioeconomic status (SES) to cognitive development in 5–12 year old Santal children of Purulia district of West Bengal, India.Methods: The nutritional status of each child was assessed by z-score of height-for-age, weight-for-height and weight-for-age parameters. SES was measured using the updated Kuppusswami scale. Cognitive development was measured by Raven's Coloured Progressive Matrices (RCPM).Results: The growth curve of RCPM scores of Santal children remained around the 5th percentile values of British children. The RCPM scores of the adequately nourished children and upper-lower SES were significantly higher (p < 0.05) than the children with lower SES and nutritional status. About 42.96% and 27.69% of Santal children were found to be in the intellectually deficient and below average groups, respectively. RCPM scores of Santal children were significantly correlated with nutritional status and socioeconomic factors (p < 0.01).Conclusion: The surveyed children showed poor cognitive functions. The vulnerable nutritional and socioeconomic statuses of Santal children are the major causes for their poor cognitive development.

Performance of Greek Demented and Nondemented Subjects on the Greek Version of the Mattis Dementia Rating Scale. A Validation Study

ABSTRACTA translated version of the Mattis Dementia Rating Scale (DRS) into Greek ((DRS-GR) was applied to a sample of Greek population (N = 356) comprising normal middle-aged and elderly subjects (controls), as well as patients suffering from Parkinson's (PD) and Alzheimer's disease (AD) to test its reliability and validity. A well-known dementia screening instrument, the Mini Mental State Examination test (MMSE), and a nonverbal measure of abstract reasoning, the Raven Coloured Progressive Matrices, were employed as measures of DRS-GR concurrent validity. Reliability analysis was satisfactory with Cronbach's alpha reaching 0.82 and item to total correlations yielding high coefficients for most items. DRS-GR scores were influenced by age and education, but not by gender. Correlation between MMSE and the total DRS-GR score was significant in patients and normal controls, but correlation between DRS-GR and RCPM was significant in AD and nondemented PD only. Specificity and sensitivity for dementia screening, calculated on a Receiver Operating Characteristic curve, with a cut-off score the mean value minus two standard deviations, corrected for age and education, was 96% and 80%, respectively. Our preliminary findings show that DRS-GR is a reliable and well-adapted instrument for clinical application in the Greek population.

Deterioration of abstract reasoning ability in mild cognitive impairment and Alzheimer’s disease: correlation with regional grey matter volume loss revealed by diffeomorphic anatomical registration through exponentiated lie algebra analysis

To determine which brain regions are relevant to deterioration in abstract reasoning as measured by Raven's Colored Progressive Matrices (CPM) in the context of dementia. MR images of 37 consecutive patients including 19 with Alzheimer's disease (AD) and 18 with amnestic mild cognitive impairment (aMCI) were retrospectively analyzed. All patients were administered the CPM. Regional grey matter (GM) volume was evaluated according to the regimens of voxel-based morphometry, during which a non-linear registration algorithm called Diffeomorphic Anatomical Registration Through Exponentiated Lie algebra was employed. Multiple regression analyses were used to map the regions where GM volumes were correlated with CPM scores. The strongest correlation with CPM scores was seen in the left middle frontal gyrus while a region with the largest volume was identified in the left superior temporal gyrus. Significant correlations were seen in 14 additional regions in the bilateral cerebral hemispheres and right cerebellum. Deterioration of abstract reasoning ability in AD and aMCI measured by CPM is related to GM loss in multiple regions, which is in close agreement with the results of previous activation studies.

Prenatal Exposure to Airborne Polycyclic Aromatic Hydrocarbons and Children’s Intelligence at 5 Years of Age in a Prospective Cohort Study in Poland

BackgroundIn this prospective cohort study of Caucasian mothers and children in Krakow, Poland, we evaluated the role of prenatal exposure to urban air pollutants in the pathogenesis of neurobehavioral disorders.ObjectivesThe objective of this study was to investigate the relationship between prenatal polycyclic aromatic hydrocarbon (PAH) exposure and child intelligence at 5 years of age, controlling for potential confounders suspected to play a role in neurodevelopment.MethodsA cohort of pregnant, healthy, nonsmoking women was enrolled in Krakow, Poland, between 2001 and 2006. During pregnancy, participants were invited to complete a questionnaire and undergo 48-hr personal air monitoring to estimate their babies’ exposure, and to provide a blood sample and/or a cord blood sample at the time of delivery. Two hundred fourteen children were followed through 5 years of age, when their nonverbal reasoning ability was assessed using the Raven Coloured Progressive Matrices (RCPM).ResultsWe found that higher (above the median of 17.96 ng/m3) prenatal exposure to airborne PAHs (range, 1.8–272.2 ng/m3) was associated with decreased RCPM scores at 5 years of age, after adjusting for potential confounding variables (n = 214). Further adjusting for maternal intelligence, lead, or dietary PAHs did not alter this association. The reduction in RCPM score associated with high airborne PAH exposure corresponded to an estimated average decrease of 3.8 IQ points.ConclusionsThese results suggest that prenatal exposure to airborne PAHs adversely affects children’s cognitive development by 5 years of age, with potential implications for school performance. They are consistent with a recent finding in a parallel cohort in New York City.

Assessment of the Capacity to Express Informed Consent for Organ Donation in Patients with Schizophrenia

In Italy, the "silent-consent" principle of donor's willingness regulates organ donation for postmortem transplantation, but civil incompetence excludes it. We investigated decisional capacity for organ donation for transplantation of 30 controls and 30 nonincompetent patients with schizophrenia as related to clinical symptoms, cognition, and functioning. Assessments were carried out through the Competence for Donation Assessment Scale (CDAS), Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Positive Symptoms (SAPS), Scale for the Assessment of Negative Symptoms, Life Skills Profile (LSP), Raven's Colored Progressive Matrices (RCPM), Wisconsin Card Sorting Test, Rey RI, Rey RD, and Visual Search. Patients and controls differed on the CDAS Understanding and Choice Expression areas. Patients showed significant inverse bivariate correlations between CDAS Understanding and scores on total BPRS, LSP self-care scale, and RCPM cognitive test. Our results show that decisional capacity for participating in research does not predict decisional capacity for postmortem organ donation in patients with schizophrenic or schizoaffective psychosis; hence, before judging consent for donation, patients must be provided with enhanced information to better understand this delicate issue.

Anthropometric measures and cognitive performance of mother‐child pairs from Sidama, Southern Ethiopia

Cognitive performance of 100 mothers and their 5 year old children was assessed using Raven's Colored Progressive Matrices (CPM) and tests from the Kaufman ABC‐II. Anthropometric measurements revealed that maternal BMI ranged from 15.3 to 29.0 with 14% having BMI &lt;18.5. Stunting in children was 29% and 12% were underweight. If mothers had ≥ 5y of education, both mothers and children had significantly higher test results. Scores for mothers and children correlated for both short term memory (r=0.21, p= 0.03) and visual processing indices (r=0.29, p=0.004). Stunted and underweight children had lower short term memory scores than non‐stunted (p=0.0005) and underweight children (p=0.009). Visual processing scores were also lower in stunted (p=0.0001) and under‐weight (p=0.001) children. Child height, weight and age and maternal age and education predicted child visual processing index (R2 = 0.38, p&lt;0.0001). Child height and age, family size and roof type predicted child short term memory index (R2=0.31, p &lt;0.0001). Malnutrition in the community appeared to contribute to low cognitive performance of the subjects. Sustainable methods to alleviate malnutrition are urgently needed.
