RESUMEN

BACKGROUND: There is limited research on whether nutritional supplementation in the first 1000 d affects long-term child outcomes. We previously demonstrated that pre- and postnatal small-quantity lipid-based nutrient supplements (SQ-LNS) increased birth weight and child length at 18 mo of age in Ghana. OBJECTIVES: We aimed to investigate the effect of pre- and postnatal SQ-LNS on child growth and blood pressure at 9-11 y. METHODS: In the International Lipid-Based Nutrient Supplements (iLiNS)-DYAD-Ghana trial, 1320 females ≤20 weeks of gestation were randomly assigned to receive daily: iron and folic acid (IFA) during pregnancy and placebo during 6 mo postpartum or multiple micronutrients (MMNs) during pregnancy and 6 mo postpartum, or SQ-LNS during pregnancy and 6 mo postpartum and for their children aged from 6 to 18 mo. We re-enrolled 966 children aged 9-11 y and assessed child blood pressure, height-for-age z-score (HAZ), body mass index (BMI)-for-age z-score, waist-to-height ratio, triceps skinfold, and midupper arm circumference. We compared SQ-LNS with control (IFA + MMN) groups adjusting for child's age. RESULTS: Mean (standard deviation [SD]) HAZ in SQ-LNS and control group was -0.04 (0.96) and -0.16 (0.99); P = 0.060. There were no indications of group differences in the other outcomes (P > 0.10). Effects on HAZ varied by child sex (P-interaction = 0.075) and maternal prepregnancy BMI (kg/m2; P-interaction = 0.007). Among females, HAZ was higher in the SQ-LNS [0.08 (1.04)] than in the control group [-0.16 (1.01)] (P = 0.010); among males, SQ-LNS [-0.16 (0.85)] and control groups [-0.16 (0.96)] did not differ (P = 0.974). Among children of females with BMI of <25, HAZ was higher in the SQ-LNS [-0.04 (1.00)] than in the control group [-0.29 (0.94)] (P = 0.004); among females with BMI of ≥25, SQ-LNS [-0.04 (0.91)] and control groups [0.07 (1.00)] did not differ (P = 0.281). CONCLUSIONS: There is a sustained impact of prenatal and postnatal SQ-LNS on linear growth among female children and children whose mothers were not overweight. This trial was registered at clinicaltrials.gov as NCT00970866 (https://clinicaltrials.gov/ct2/show/record/NCT00970866).

RESUMEN

BACKGROUND: Provision of small-quantity lipid-based nutrient supplements (SQ-LNSs) during early life improves growth and development. In the International Lipid-Based Nutrient Supplements DYAD-Ghana trial, prenatal and postnatal SQ-LNS reduced social-emotional difficulties at age 5 y, with greater effects among children in less-enriched home environments. OBJECTIVES: We aimed to investigate the effect of prenatal and postnatal SQ-LNS on children's social-emotional problems at age 9-11 y. METHODS: In 2009-2011, 1320 pregnant women ≤20 wk gestation were randomly assigned to receive the following daily until 6 mo postpartum: 1) iron and folic acid until delivery, then placebo, 2) multiple micronutrients (MMNs), or 3) SQ-LNS (20 g/d). Children in group 3 received SQ-LNS from 6 to 18 mo. In 2021, we evaluated children's social-emotional outcomes with 6 assessment tools that used caregiver, teacher, and/or self-report to measure socioemotional difficulties, conduct problems, temperament, mood, anxiety, and emotion management. RESULTS: We assessed outcomes in 966 children, comprising 79.4% of 1217 participants eligible for re-enrolment. No significant differences were found between the SQ-LNS and control (non-LNS groups combined) groups. Few children (<2%) experienced high parent-reported social-emotional difficulties at 9-11 y, in contrast to the high prevalence at age 5 in this cohort (25%). Among children in less-enriched early childhood home environments, the SQ-LNS group had 0.37 SD (-0.04 to 0.82) lower self-reported conduct problems than the control group (P-interaction = 0.047). CONCLUSIONS: Overall positive effects of SQ-LNS on social-emotional development previously found at age 5 y are not sustained to age 9-11 y; however, there is some evidence of positive effects among children in less-enriched environments. The lack of effects may be owing to low prevalence of social-emotional problems at preadolescence, resulting in little potential to benefit from early nutritional intervention at this age in this outcome domain. Follow-up during adolescence, when social-emotional problems more typically onset, may yield further insights. This trial was registered at clinicaltrials.gov as NCT00970866. https://clinicaltrials.gov/ct2/show/record/NCT00970866.

RESUMEN

Ageing in sickle cell disease (SCD) is associated with a myriad of end-organ complications, including cerebrovascular damage and cognitive impairment (CI). Although CI is very common in SCD, little is known about cognitive functioning and how it changes with age. This study examines cognitive patterns of 63 adults with SCD and 60 non-SCD, age- and education-matched controls in Ghana. Of those adults with SCD, 34 completed the neuropsychological battery at baseline and again seven years later. In cross-sectional data, adults with SCD performed worse than controls in all cognitive test domains (p < 0.01 for all). The seven-year follow-up data showed that the group exhibited a significant decline in visuospatial abilities (ranging from Cohen's d = 1.40 to 2.38), and to a lesser extent, in processing speed and executive functioning. Exploratory analyses showed a significant time-by-education interaction, indicating that education may be protective from decline in cognitive performance. These findings have implications for clinical practice. Early neuropsychological surveillance coupled with early assessment and remedial programmes will provide avenues for enhancing the quality of life of adults living with SCD in Ghana.

RESUMEN

This study investigated the causes of homelessness in Ghana and associated psychosocial distress. A sample of 86 homeless participants listed perceived causes of their homelessness and completed measures of psychosocial distress, and 97 non-homeless participants completed the same measures psychosocial distress. Causes of homelessness among the participants included poverty (30.1%), migration (10.4%), unemployment (2.2%), parental demise (2.2%), parental neglect (0.5%), and parental divorce (0.5%). Multivariate analysis revealed higher psychosocial distress among the homeless than the non-homeless. Homeless females reported higher levels of stress and suicidality than their male counterparts. The study demonstrates the need for timely and effective implementation of interventions such as provision of affordable housing, financial assistance, job-creation, and skill training for the homeless directly related to known causes of homelessness and accounting for gender differences.

RESUMEN

The study explored the mediating role of resilience in the relationship between spirituality and subjective well-being of 107 Ghanaian biological parents raising children with special needs. Results from mediational analyses revealed that spirituality indirectly influenced life satisfaction, positive affect and negative affect through resilience. Specifically, greater levels of spirituality predicted greater resilience, which successively led to greater life satisfaction, greater positive affect and reduced negative affect. These findings emphasize the necessity of targeting parents' well-being through resilience to help them deal with the burden of providing care for their children with special needs.

RESUMEN

BACKGROUND: While parenting a child with special needs is burdensome, some parents do overcome through protective resources. Social support has been widely linked to this unique ability to overcome the challenges of raising a child with special needs. In spite of this, there is still paucity of research about the influence of the sources of perceived social support on this ability, known as resilience. AIM: This study examined three sources of perceived social support-family, friends and significant other-on the resilience of Ghanaian parents raising children with special needs while adjusting for covariates (parental gender, marital status and educational level). METHODS: One hundred and seven (107) biological parents were recruited from special schools and parents support groups in Accra, Ghana. They completed paper-and-pencil or online questionnaires on resilience and perceived social support. RESULTS: Output from hierarchical multiple regression after adjusting for covariates showed that only support from significant others predicted resilience. Additionally, being married was positively and holding a higher education was inversely associated with resilience. CONCLUSION AND IMPLICATION: These findings indicate the importance of support from significant others in the resiliency of parents but underscore the need to fully integrate and emphasize support from the other sources in resilience enhancing interventions.

RESUMEN

Markus and Kitayama's (1991) theory of independent and interdependent self-construals had a major influence on social, personality, and developmental psychology by highlighting the role of culture in psychological processes. However, research has relied excessively on contrasts between North American and East Asian samples, and commonly used self-report measures of independence and interdependence frequently fail to show predicted cultural differences. We revisited the conceptualization and measurement of independent and interdependent self-construals in 2 large-scale multinational surveys, using improved methods for cross-cultural research. We developed (Study 1: N = 2924 students in 16 nations) and validated across cultures (Study 2: N = 7279 adults from 55 cultural groups in 33 nations) a new 7-dimensional model of self-reported ways of being independent or interdependent. Patterns of global variation support some of Markus and Kitayama's predictions, but a simple contrast between independence and interdependence does not adequately capture the diverse models of selfhood that prevail in different world regions. Cultural groups emphasize different ways of being both independent and interdependent, depending on individualism-collectivism, national socioeconomic development, and religious heritage. Our 7-dimensional model will allow future researchers to test more accurately the implications of cultural models of selfhood for psychological processes in diverse ecocultural contexts.

RESUMEN

Variations in acquiescence and extremity pose substantial threats to the validity of cross-cultural research that relies on survey methods. Individual and cultural correlates of response styles when using 2 contrasting types of response mode were investigated, drawing on data from 55 cultural groups across 33 nations. Using 7 dimensions of self-other relatedness that have often been confounded within the broader distinction between independence and interdependence, our analysis yields more specific understandings of both individual- and culture-level variations in response style. When using a Likert-scale response format, acquiescence is strongest among individuals seeing themselves as similar to others, and where cultural models of selfhood favour harmony, similarity with others and receptiveness to influence. However, when using Schwartz's (2007) portrait-comparison response procedure, acquiescence is strongest among individuals seeing themselves as self-reliant but also connected to others, and where cultural models of selfhood favour self-reliance and self-consistency. Extreme responding varies less between the two types of response modes, and is most prevalent among individuals seeing themselves as self-reliant, and in cultures favouring self-reliance. As both types of response mode elicit distinctive styles of response, it remains important to estimate and control for style effects to ensure valid comparisons.

RESUMEN

The hypothesis of whether day length (photoperiod) is an important zeitgeber (time-giver) for keeping the circadian rhythm entrained to a 24-hour cycle was examined, as was its association with sleep patterns and mood problems. Data were collected prospectively from a site with very large differences in daylight duration across seasons (Tromsø in Norway, 69°39'N) and a site with very small seasonal differences in daylight duration (Ghana in Accra, 5°32'N). Two hundred subjects were recruited from both sites in January. At the follow-up in August, 180 and 150 subjects in Ghana and Norway participated, respectively. Use of a weekly sleep diary indicated low to moderately strong seasonal changes in rise- and bedtime, sleep efficiency and sleep onset latency only in the northern latitude. No seasonal changes in sleep duration or night awakenings were observed. The self-report measures indicated moderate to strong seasonal differences in insomnia and fatigue, and weaker differences in depressed mood in Norway, but small to non-existing seasonal differences in Ghana. Lack of daylight was related to phase-delayed rise- and bedtimes, increased problems falling asleep, daytime fatigue and depressive mood. However, total sleep duration and sleep quality appeared unaffected.
